OAuth2

Spring Security 提供全面的 OAuth 2.0 支持。本节讨论如何将 OAuth 2.0 集成到基于 Servlet 的应用程序中。spring-doc.cadn.net.cn

概述

Spring Security 的 OAuth 2.0 支持由两个主要功能集组成：spring-doc.cadn.net.cn

OAuth2 登录是一个非常强大的 OAuth2 客户端功能，值得在参考文档中单独列出一节。但是，它不作为独立功能存在，需要 OAuth2 客户端才能运行。spring-doc.cadn.net.cn

这些功能集涵盖了 OAuth 2.0 授权框架中定义的资源服务器和客户端角色，而授权服务器角色则由 Spring Authorization Server 覆盖，Spring Authorization Server 是一个基于 Spring Security 构建的单独项目。spring-doc.cadn.net.cn

OAuth2 中的资源服务器和客户端角色通常由一个或多个服务器端应用程序表示。此外，授权服务器角色可以由一个或多个第三方表示（就像在组织内集中身份管理和/或身份验证时一样），或者它可以由应用程序表示（就像 Spring Authorization Server 的情况一样）。spring-doc.cadn.net.cn

例如，典型的基于 OAuth2 的微服务架构可能由单个面向用户的客户端应用程序、多个提供 REST API 的后端资源服务器以及用于管理用户和身份验证问题的第三方授权服务器组成。通常，单个应用程序仅代表这些角色之一，并且需要与提供其他角色的一个或多个第三方集成。spring-doc.cadn.net.cn

Spring Security 处理这些场景以及更多场景。以下部分介绍了 Spring Security 提供的角色，并包含常见场景的示例。spring-doc.cadn.net.cn

OAuth2 资源服务器

本节包含 OAuth2 资源服务器功能及其示例的摘要。有关完整的参考文档，请参阅 OAuth 2.0 资源服务器。spring-doc.cadn.net.cn

要开始使用，请添加spring-security-oauth2-resource-server依赖项目。使用 Spring Boot 时，添加以下Starters：spring-doc.cadn.net.cn

带有 Spring Boot 的 OAuth2 客户端

Gradlespring-doc.cadn.net.cn
Mavenspring-doc.cadn.net.cn

implementation 'org.springframework.boot:spring-boot-starter-oauth2-resource-server'

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-oauth2-resource-server</artifactId>
</dependency>

有关不使用 Spring Boot 时的其他选项，请参阅获取 Spring Security。spring-doc.cadn.net.cn

考虑 OAuth2 资源服务器的以下用例：spring-doc.cadn.net.cn

我想使用 OAuth2 保护对 API 的访问（授权服务器提供 JWT 或不透明访问Tokens）spring-doc.cadn.net.cn
我想使用 JWT（自定义Tokens）保护对 API 的访问 spring-doc.cadn.net.cn

使用 OAuth2 访问Tokens保护访问

使用 OAuth2 访问Tokens保护对 API 的访问是很常见的。在大多数情况下，Spring Security 只需要最少的配置即可使用 OAuth2 保护应用程序。spring-doc.cadn.net.cn

有两种类型BearerSpring Security 支持的Tokens，每个Tokens都使用不同的组件进行验证：spring-doc.cadn.net.cn

JWT 支持使用JwtDecoder用于验证签名和解码Tokens的 beanspring-doc.cadn.net.cn
不透明Tokens支持使用OpaqueTokenIntrospectorbean 到 Introspect Tokensspring-doc.cadn.net.cn

JWT 支持

以下示例配置JwtDecoderbean 使用 Spring Boot 配置属性：spring-doc.cadn.net.cn

spring:
  security:
    oauth2:
      resourceserver:
        jwt:
          issuer-uri: https://my-auth-server.com

使用 Spring Boot 时，只需这样做即可。 Spring Boot提供的默认排列方式相当于以下内容：spring-doc.cadn.net.cn

使用 JWT 配置资源服务器

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
@EnableWebSecurity
public class SecurityConfig {

	@Bean
	public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
		http
			.authorizeHttpRequests((authorize) -> authorize
				.anyRequest().authenticated()
			)
			.oauth2ResourceServer((oauth2) -> oauth2
				.jwt(Customizer.withDefaults())
			);
		return http.build();
	}

	@Bean
	public JwtDecoder jwtDecoder() {
		return JwtDecoders.fromIssuerLocation("https://my-auth-server.com");
	}

}

import org.springframework.security.config.annotation.web.invoke

@Configuration
@EnableWebSecurity
class SecurityConfig {

	@Bean
	fun securityFilterChain(http: HttpSecurity): SecurityFilterChain {
		http {
			authorizeHttpRequests {
				authorize(anyRequest, authenticated)
			}
			oauth2ResourceServer {
				jwt { }
			}
		}

		return http.build()
	}

	@Bean
	fun jwtDecoder(): JwtDecoder {
		return JwtDecoders.fromIssuerLocation("https://my-auth-server.com")
	}

}

不透明Tokens支持

以下示例配置了OpaqueTokenIntrospectorbean 使用 Spring Boot 配置属性：spring-doc.cadn.net.cn

spring:
  security:
    oauth2:
      resourceserver:
        opaquetoken:
          introspection-uri: https://my-auth-server.com/oauth2/introspect
          client-id: my-client-id
          client-secret: my-client-secret

使用 Spring Boot 时，只需这样做即可。 Spring Boot提供的默认排列方式相当于以下内容：spring-doc.cadn.net.cn

使用不透明Tokens配置资源服务器

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
@EnableWebSecurity
public class SecurityConfig {

	@Bean
	public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
		http
			.authorizeHttpRequests((authorize) -> authorize
				.anyRequest().authenticated()
			)
			.oauth2ResourceServer((oauth2) -> oauth2
				.opaqueToken(Customizer.withDefaults())
			);
		return http.build();
	}

	@Bean
	public OpaqueTokenIntrospector opaqueTokenIntrospector() {
		return new SpringOpaqueTokenIntrospector(
			"https://my-auth-server.com/oauth2/introspect", "my-client-id", "my-client-secret");
	}

}

import org.springframework.security.config.annotation.web.invoke

@Configuration
@EnableWebSecurity
class SecurityConfig {

	@Bean
	fun securityFilterChain(http: HttpSecurity): SecurityFilterChain {
		http {
			authorizeHttpRequests {
				authorize(anyRequest, authenticated)
			}
			oauth2ResourceServer {
				opaqueToken { }
			}
		}

		return http.build()
	}

	@Bean
	fun opaqueTokenIntrospector(): OpaqueTokenIntrospector {
		return SpringOpaqueTokenIntrospector(
			"https://my-auth-server.com/oauth2/introspect", "my-client-id", "my-client-secret"
		)
	}

}

使用自定义 JWT 保护访问

使用 JWT 保护对 API 的访问是一个相当普遍的目标，特别是当前端被开发为单页应用程序时。 Spring Security 中的 OAuth2 资源服务器支持可用于任何类型的BearerTokens，包括自定义 JWT。spring-doc.cadn.net.cn

使用 JWT 保护 API 所需的只是一个JwtDecoderbean，用于验证签名和解码Tokens。 Spring Security 将自动使用提供的 bean 在SecurityFilterChain.spring-doc.cadn.net.cn

以下示例配置JwtDecoderbean 使用 Spring Boot 配置属性：spring-doc.cadn.net.cn

spring:
  security:
    oauth2:
      resourceserver:
        jwt:
          public-key-location: classpath:my-public-key.pub

您可以将公密钥作为类路径资源（称为my-public-key.pub在本例中）。spring-doc.cadn.net.cn

使用 Spring Boot 时，只需这样做即可。 Spring Boot提供的默认排列方式相当于以下内容：spring-doc.cadn.net.cn

使用自定义 JWT 配置资源服务器

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
@EnableWebSecurity
public class SecurityConfig {

	@Bean
	public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
		http
			.authorizeHttpRequests((authorize) -> authorize
				.anyRequest().authenticated()
			)
			.oauth2ResourceServer((oauth2) -> oauth2
				.jwt(Customizer.withDefaults())
			);
		return http.build();
	}

	@Bean
	public JwtDecoder jwtDecoder() {
		return NimbusJwtDecoder.withPublicKey(publicKey()).build();
	}

	private RSAPublicKey publicKey() {
		// ...
	}

}

import org.springframework.security.config.annotation.web.invoke

@Configuration
@EnableWebSecurity
class SecurityConfig {

	@Bean
	fun securityFilterChain(http: HttpSecurity): SecurityFilterChain {
		http {
			authorizeHttpRequests {
				authorize(anyRequest, authenticated)
			}
			oauth2ResourceServer {
				jwt { }
			}
		}

		return http.build()
	}

	@Bean
	fun jwtDecoder(): JwtDecoder {
		return NimbusJwtDecoder.withPublicKey(publicKey()).build()
	}

	private fun publicKey(): RSAPublicKey {
		// ...
	}

}

Spring Security 不提供用于铸造Tokens的端点。但是，Spring Security 确实提供了JwtEncoder接口以及一个实现，即NimbusJwtEncoder.spring-doc.cadn.net.cn

OAuth2 客户端

本节包含 OAuth2 客户端功能的摘要和示例。有关完整的参考文档，请参阅 OAuth 2.0 客户端和 OAuth 2.0 登录。spring-doc.cadn.net.cn

要开始使用，请添加spring-security-oauth2-client依赖项目。使用 Spring Boot 时，添加以下Starters：spring-doc.cadn.net.cn

带有 Spring Boot 的 OAuth2 客户端

Gradlespring-doc.cadn.net.cn
Mavenspring-doc.cadn.net.cn

implementation 'org.springframework.boot:spring-boot-starter-oauth2-client'

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-oauth2-client</artifactId>
</dependency>

有关不使用 Spring Boot 时的其他选项，请参阅获取 Spring Security。spring-doc.cadn.net.cn

考虑 OAuth2 客户端的以下用例：spring-doc.cadn.net.cn

我想使用 OAuth 2.0 或 OpenID Connect 1.0 登录用户 spring-doc.cadn.net.cn
我想用RestClient获取用户的访问Tokens为了访问第三方 APIspring-doc.cadn.net.cn
我想用WebClient获取用户的访问Tokens为了访问第三方 APIspring-doc.cadn.net.cn
我想同时执行这两个作（登录用户并访问第三方 API）spring-doc.cadn.net.cn
我想使用client_credentials授权类型为每个应用程序获取单个Tokensspring-doc.cadn.net.cn
我想启用延期授权类型 spring-doc.cadn.net.cn
我想自定义现有授权类型 spring-doc.cadn.net.cn
我想自定义Tokens请求参数 spring-doc.cadn.net.cn
我想自定义RestClient由 OAuth2 客户端组件使用 spring-doc.cadn.net.cn

使用 OAuth2 登录用户

要求用户通过 OAuth2 登录是很常见的。OpenID Connect 1.0 提供了一个名为id_token旨在为 OAuth2 客户端提供执行用户身份验证和登录用户的能力。在某些情况下，OAuth2 可以直接用于登录用户（例如未实现 OpenID Connect 的流行社交登录提供商，例如 GitHub 和 Facebook）。spring-doc.cadn.net.cn

以下示例将应用程序配置为充当能够使用 OAuth2 或 OpenID Connect 登录用户的 OAuth2 客户端：spring-doc.cadn.net.cn

配置 OAuth2 登录

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
@EnableWebSecurity
public class SecurityConfig {

	@Bean
	public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.oauth2Login(Customizer.withDefaults());
		return http.build();
	}

}

import org.springframework.security.config.annotation.web.invoke

@Configuration
@EnableWebSecurity
class SecurityConfig {

	@Bean
	fun securityFilterChain(http: HttpSecurity): SecurityFilterChain {
		http {
			// ...
			oauth2Login { }
		}

		return http.build()
	}

}

除了上述配置外，应用程序还需要至少一个ClientRegistration通过使用ClientRegistrationRepository豆。以下示例配置了InMemoryClientRegistrationRepositorybean 使用 Spring Boot 配置属性：spring-doc.cadn.net.cn

spring:
  security:
    oauth2:
      client:
        registration:
          my-oidc-client:
            provider: my-oidc-provider
            client-id: my-client-id
            client-secret: my-client-secret
            authorization-grant-type: authorization_code
            scope: openid,profile
        provider:
          my-oidc-provider:
            issuer-uri: https://my-oidc-provider.com

通过上述配置，应用程序现在支持两个额外的终结点：spring-doc.cadn.net.cn

登录端点（例如/oauth2/authorization/my-oidc-client）用于启动登录并执行重定向到第三方授权服务器。spring-doc.cadn.net.cn
重定向端点（例如/login/oauth2/code/my-oidc-client）被授权服务器用来重定向回客户端应用程序，并且将包含一个code参数用于获取id_token和/或access_token通过访问Tokens请求。spring-doc.cadn.net.cn

的存在openidscope 表示应使用 OpenID Connect 1.0。这指示 Spring Security 使用特定于 OIDC 的组件（例如OidcUserService）在请求处理期间。如果没有此范围，Spring Security 将使用特定于 OAuth2 的组件（例如DefaultOAuth2UserService）代替。spring-doc.cadn.net.cn

访问受保护的资源

向受 OAuth2 保护的第三方 API 发出请求是 OAuth2 客户端的核心用例。这是通过授权客户端（由OAuth2AuthorizedClient类）并通过放置Bearertoken 中的Authorization出站请求的标头。spring-doc.cadn.net.cn

以下示例将应用程序配置为充当能够从第三方 API 请求受保护资源的 OAuth2 客户端：spring-doc.cadn.net.cn

配置 OAuth2 客户端

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
@EnableWebSecurity
public class SecurityConfig {

	@Bean
	public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.oauth2Client(Customizer.withDefaults());
		return http.build();
	}

}

import org.springframework.security.config.annotation.web.invoke

@Configuration
@EnableWebSecurity
class SecurityConfig {

	@Bean
	fun securityFilterChain(http: HttpSecurity): SecurityFilterChain {
		http {
			// ...
			oauth2Client { }
		}

		return http.build()
	}

}

上面的示例没有提供登录用户的方法。您可以使用任何其他登录机制（例如formLogin()). 请参阅下一节，了解组合示例oauth2Client()跟oauth2Login().spring-doc.cadn.net.cn

spring:
  security:
    oauth2:
      client:
        registration:
          my-oauth2-client:
            provider: my-auth-server
            client-id: my-client-id
            client-secret: my-client-secret
            authorization-grant-type: authorization_code
            scope: message.read,message.write
        provider:
          my-auth-server:
            issuer-uri: https://my-auth-server.com

除了配置 Spring Security 以支持 OAuth2 客户端功能外，您还需要决定如何访问受保护的资源并相应地配置您的应用程序。 Spring Security 提供了OAuth2AuthorizedClientManager用于获取可用于访问受保护资源的访问Tokens。spring-doc.cadn.net.cn

Spring Security 注册默认值OAuth2AuthorizedClientManager当一个不存在时，你会遇到一个豆。spring-doc.cadn.net.cn

使用OAuth2AuthorizedClientManager是通过一个ClientHttpRequestInterceptor通过RestClient，当spring-web在类路径上。spring-doc.cadn.net.cn

以下示例使用默认的OAuth2AuthorizedClientManager配置RestClient能够通过放置BearerTokens中的Authorization每个请求的标头：spring-doc.cadn.net.cn

配置RestClient跟ClientHttpRequestInterceptor

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
public class RestClientConfig {

	@Bean
	public RestClient restClient(OAuth2AuthorizedClientManager authorizedClientManager) {
		OAuth2ClientHttpRequestInterceptor requestInterceptor =
				new OAuth2ClientHttpRequestInterceptor(authorizedClientManager);
		return RestClient.builder()
				.requestInterceptor(requestInterceptor)
				.build();
	}

}

@Configuration
class RestClientConfig {

	@Bean
	fun restClient(authorizedClientManager: OAuth2AuthorizedClientManager): RestClient {
		val requestInterceptor = OAuth2ClientHttpRequestInterceptor(authorizedClientManager)
		return RestClient.builder()
			.requestInterceptor(requestInterceptor)
			.build()
	}

}

这配置了RestClient可以如以下示例所示：spring-doc.cadn.net.cn

用RestClient访问受保护资源

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

import static org.springframework.security.oauth2.client.web.client.RequestAttributeClientRegistrationIdResolver.clientRegistrationId;

@RestController
public class MessagesController {

	private final RestClient restClient;

	public MessagesController(RestClient restClient) {
		this.restClient = restClient;
	}

	@GetMapping("/messages")
	public ResponseEntity<List<Message>> messages() {
		Message[] messages = this.restClient.get()
				.uri("http://localhost:8090/messages")
				.attributes(clientRegistrationId("my-oauth2-client"))
				.retrieve()
				.body(Message[].class);
		return ResponseEntity.ok(Arrays.asList(messages));
	}

	public record Message(String message) {
	}

}

import org.springframework.security.oauth2.client.web.client.RequestAttributeClientRegistrationIdResolver.clientRegistrationId
import org.springframework.web.client.body

@RestController
class MessagesController(private val restClient: RestClient) {

	@GetMapping("/messages")
	fun messages(): ResponseEntity<List<Message>> {
		val messages = restClient.get()
			.uri("http://localhost:8090/messages")
			.attributes(clientRegistrationId("my-oauth2-client"))
			.retrieve()
			.body<Array<Message>>()!!
			.toList()
		return ResponseEntity.ok(messages)
	}

	data class Message(val message: String)

}

访问受保护的资源`WebClient`

以下示例将应用程序配置为充当能够从第三方 API 请求受保护资源的 OAuth2 客户端：spring-doc.cadn.net.cn

配置 OAuth2 客户端

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
@EnableWebSecurity
public class SecurityConfig {

	@Bean
	public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.oauth2Client(Customizer.withDefaults());
		return http.build();
	}

}

import org.springframework.security.config.annotation.web.invoke

@Configuration
@EnableWebSecurity
class SecurityConfig {

	@Bean
	fun securityFilterChain(http: HttpSecurity): SecurityFilterChain {
		http {
			// ...
			oauth2Client { }
		}

		return http.build()
	}

}

上面的示例没有提供登录用户的方法。您可以使用任何其他登录机制（例如formLogin()). 有关组合示例，请参阅上一节oauth2Client()跟oauth2Login().spring-doc.cadn.net.cn

spring:
  security:
    oauth2:
      client:
        registration:
          my-oauth2-client:
            provider: my-auth-server
            client-id: my-client-id
            client-secret: my-client-secret
            authorization-grant-type: authorization_code
            scope: message.read,message.write
        provider:
          my-auth-server:
            issuer-uri: https://my-auth-server.com

Spring Security 注册默认值OAuth2AuthorizedClientManager当一个不存在时，你会遇到一个豆。spring-doc.cadn.net.cn

而不是配置RestClient，另一种使用OAuth2AuthorizedClientManager是通过ExchangeFilterFunction通过WebClient. 使用WebClient，您需要添加spring-webflux依赖关系以及响应式客户端实现：spring-doc.cadn.net.cn

添加 Spring WebFlux 依赖项

Gradlespring-doc.cadn.net.cn
Mavenspring-doc.cadn.net.cn

implementation 'org.springframework:spring-webflux'
implementation 'io.projectreactor.netty:reactor-netty'

<dependency>
	<groupId>org.springframework</groupId>
	<artifactId>spring-webflux</artifactId>
</dependency>
<dependency>
	<groupId>io.projectreactor.netty</groupId>
	<artifactId>reactor-netty</artifactId>
</dependency>

以下示例使用默认的OAuth2AuthorizedClientManager配置WebClient能够通过放置BearerTokens中的Authorization每个请求的标头：spring-doc.cadn.net.cn

配置WebClient跟ExchangeFilterFunction

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
public class WebClientConfig {

	@Bean
	public WebClient webClient(OAuth2AuthorizedClientManager authorizedClientManager) {
		ServletOAuth2AuthorizedClientExchangeFilterFunction filter =
				new ServletOAuth2AuthorizedClientExchangeFilterFunction(authorizedClientManager);
		return WebClient.builder()
				.apply(filter.oauth2Configuration())
				.build();
	}

}

@Configuration
class WebClientConfig {

	@Bean
	fun webClient(authorizedClientManager: OAuth2AuthorizedClientManager): WebClient {
		val filter = ServletOAuth2AuthorizedClientExchangeFilterFunction(authorizedClientManager)
		return WebClient.builder()
			.apply(filter.oauth2Configuration())
			.build()
	}

}

这配置了WebClient可以如以下示例所示：spring-doc.cadn.net.cn

用WebClient访问受保护资源

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

import static org.springframework.security.oauth2.client.web.reactive.function.client.ServletOAuth2AuthorizedClientExchangeFilterFunction.clientRegistrationId;

@RestController
public class MessagesController {

	private final WebClient webClient;

	public MessagesController(WebClient webClient) {
		this.webClient = webClient;
	}

	@GetMapping("/messages")
	public ResponseEntity<List<Message>> messages() {
		return this.webClient.get()
				.uri("http://localhost:8090/messages")
				.attributes(clientRegistrationId("my-oauth2-client"))
				.retrieve()
				.toEntityList(Message.class)
				.block();
	}

	public record Message(String message) {
	}

}

import org.springframework.security.oauth2.client.web.reactive.function.client.ServletOAuth2AuthorizedClientExchangeFilterFunction.clientRegistrationId

@RestController
class MessagesController(private val webClient: WebClient) {

	@GetMapping("/messages")
	fun messages(): ResponseEntity<List<Message>> {
		return webClient.get()
			.uri("http://localhost:8090/messages")
			.attributes(clientRegistrationId("my-oauth2-client"))
			.retrieve()
			.toEntityList<Message>()
			.block()!!
	}

	data class Message(val message: String)

}

访问当前用户的受保护资源

当用户通过 OAuth2 或 OpenID Connect 登录时，授权服务器可能会提供一个访问Tokens，该Tokens可直接用于访问受保护的资源。这很方便，因为它只需要一个ClientRegistration同时为两个用例进行配置。spring-doc.cadn.net.cn

本节将使用 OAuth2 登录用户和访问受保护资源合并到单个配置中。还存在其他高级方案，例如配置一个ClientRegistration用于登录，另一个用于访问受保护资源。所有这些方案都将使用相同的基本配置。spring-doc.cadn.net.cn

以下示例将应用程序配置为充当 OAuth2 客户端，能够登录用户并从第三方 API 请求受保护的资源：spring-doc.cadn.net.cn

配置 OAuth2 登录和 OAuth2 客户端

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
@EnableWebSecurity
public class SecurityConfig {

	@Bean
	public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
		http
			// ...
			.oauth2Login(Customizer.withDefaults())
			.oauth2Client(Customizer.withDefaults());
		return http.build();
	}

}

import org.springframework.security.config.annotation.web.invoke

@Configuration
@EnableWebSecurity
class SecurityConfig {

	@Bean
	fun securityFilterChain(http: HttpSecurity): SecurityFilterChain {
		http {
			// ...
			oauth2Login { }
			oauth2Client { }
		}

		return http.build()
	}

}

spring:
  security:
    oauth2:
      client:
        registration:
          my-combined-client:
            provider: my-auth-server
            client-id: my-client-id
            client-secret: my-client-secret
            authorization-grant-type: authorization_code
            scope: openid,profile,message.read,message.write
        provider:
          my-auth-server:
            issuer-uri: https://my-auth-server.com

前面的示例（使用 OAuth2 登录用户，访问受保护的资源）与此示例之间的主要区别在于通过scope属性，它结合了标准作用域openid和profile使用自定义范围message.read和message.write.spring-doc.cadn.net.cn

Spring Security 注册默认值OAuth2AuthorizedClientManager当一个不存在时，你会遇到一个豆。spring-doc.cadn.net.cn

使用OAuth2AuthorizedClientManager是通过一个ClientHttpRequestInterceptor通过RestClient，当spring-web在类路径上。spring-doc.cadn.net.cn

以下示例使用默认的OAuth2AuthorizedClientManager配置RestClient能够通过放置BearerTokens中的Authorization每个请求的标头：spring-doc.cadn.net.cn

配置RestClient跟ClientHttpRequestInterceptor

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
public class RestClientConfig {

	@Bean
	public RestClient restClient(OAuth2AuthorizedClientManager authorizedClientManager) {
		OAuth2ClientHttpRequestInterceptor requestInterceptor =
				new OAuth2ClientHttpRequestInterceptor(authorizedClientManager);
		requestInterceptor.setClientRegistrationIdResolver(clientRegistrationIdResolver());

		return RestClient.builder()
				.requestInterceptor(requestInterceptor)
				.build();
	}

	private static ClientRegistrationIdResolver clientRegistrationIdResolver() {
		return (request) -> {
			Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
			return (authentication instanceof OAuth2AuthenticationToken principal)
				? principal.getAuthorizedClientRegistrationId()
				: null;
		};
	}

}

@Configuration
class RestClientConfig {

	@Bean
	fun restClient(authorizedClientManager: OAuth2AuthorizedClientManager): RestClient {
		val requestInterceptor = OAuth2ClientHttpRequestInterceptor(authorizedClientManager)
		requestInterceptor.setClientRegistrationIdResolver(clientRegistrationIdResolver())

		return RestClient.builder()
			.requestInterceptor(requestInterceptor)
			.build()
	}

	private fun clientRegistrationIdResolver(): OAuth2ClientHttpRequestInterceptor.ClientRegistrationIdResolver {
		return OAuth2ClientHttpRequestInterceptor.ClientRegistrationIdResolver { request ->
			val authentication = SecurityContextHolder.getContext().authentication
			if (authentication is OAuth2AuthenticationToken) {
				authentication.authorizedClientRegistrationId
			} else {
				null
			}
		}
	}

}

这配置了RestClient可以如以下示例所示：spring-doc.cadn.net.cn

用RestClient访问受保护的资源（当前用户）

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@RestController
public class MessagesController {

	private final RestClient restClient;

	public MessagesController(RestClient restClient) {
		this.restClient = restClient;
	}

	@GetMapping("/messages")
	public ResponseEntity<List<Message>> messages() {
		Message[] messages = this.restClient.get()
				.uri("http://localhost:8090/messages")
				.retrieve()
				.body(Message[].class);
		return ResponseEntity.ok(Arrays.asList(messages));
	}

	public record Message(String message) {
	}

}

import org.springframework.web.client.body

@RestController
class MessagesController(private val restClient: RestClient) {

	@GetMapping("/messages")
	fun messages(): ResponseEntity<List<Message>> {
		val messages = restClient.get()
			.uri("http://localhost:8090/messages")
			.retrieve()
			.body<Array<Message>>()!!
			.toList()
		return ResponseEntity.ok(messages)
	}

	data class Message(val message: String)

}

与前面的示例不同，请注意，我们不需要告诉 Spring Security 有关clientRegistrationId我们想使用。这是因为它可以从当前登录的用户派生。spring-doc.cadn.net.cn

使用客户端凭据授权

本部分重点介绍客户端凭据授予类型的其他注意事项。请参阅访问受保护的资源，了解所有授权类型的常规设置和用法。spring-doc.cadn.net.cn

客户端凭据授予允许客户端获取access_token代表自己。客户端凭据授予是一个简单的流，不涉及资源所有者（即用户）。spring-doc.cadn.net.cn

请务必注意，客户端凭据授权的典型使用意味着任何请求（或用户）都有可能获取访问Tokens，并向资源服务器发出受保护的资源请求。在设计应用程序时要小心，以确保用户无法发出未经授权的请求，因为每个请求都能够获得访问Tokens。spring-doc.cadn.net.cn

在用户可以登录的 Web 应用程序中获取访问Tokens时，Spring Security 的默认行为是为每个用户获取一个访问Tokens。spring-doc.cadn.net.cn

默认情况下，访问Tokens的范围限定为当前用户的主体名称，这意味着每个用户都将收到一个唯一的访问Tokens。spring-doc.cadn.net.cn

使用客户端凭据授权的客户端通常要求访问Tokens的范围限定为应用程序而不是单个用户，因此每个应用程序只有一个访问Tokens。若要将访问Tokens的范围限定为应用程序，需要设置用于解析自定义主体名称的策略。以下示例通过配置RestClient使用RequestAttributePrincipalResolver:spring-doc.cadn.net.cn

配置RestClient为client_credentials

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
public class RestClientConfig {

	@Bean
	public RestClient restClient(OAuth2AuthorizedClientManager authorizedClientManager) {
		OAuth2ClientHttpRequestInterceptor requestInterceptor =
				new OAuth2ClientHttpRequestInterceptor(authorizedClientManager);
		requestInterceptor.setPrincipalResolver(new RequestAttributePrincipalResolver());
		return RestClient.builder()
				.requestInterceptor(requestInterceptor)
				.build();
	}

}

@Configuration
class RestClientConfig {

	@Bean
	fun restClient(authorizedClientManager: OAuth2AuthorizedClientManager): RestClient {
		val requestInterceptor = OAuth2ClientHttpRequestInterceptor(authorizedClientManager)
		requestInterceptor.setPrincipalResolver(RequestAttributePrincipalResolver())
		return RestClient.builder()
			.requestInterceptor(requestInterceptor)
			.build()
	}

}

完成上述配置后，可以为每个请求指定一个主体名称。以下示例演示了如何通过指定主体名称来将访问Tokens的范围限定为应用程序：spring-doc.cadn.net.cn

将访问Tokens范围限定为应用程序

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

import static org.springframework.security.oauth2.client.web.client.RequestAttributeClientRegistrationIdResolver.clientRegistrationId;
import static org.springframework.security.oauth2.client.web.client.RequestAttributePrincipalResolver.principal;

@RestController
public class MessagesController {

	private final RestClient restClient;

	public MessagesController(RestClient restClient) {
		this.restClient = restClient;
	}

	@GetMapping("/messages")
	public ResponseEntity<List<Message>> messages() {
		Message[] messages = this.restClient.get()
				.uri("http://localhost:8090/messages")
				.attributes(clientRegistrationId("my-oauth2-client"))
				.attributes(principal("my-application"))
				.retrieve()
				.body(Message[].class);
		return ResponseEntity.ok(Arrays.asList(messages));
	}

	public record Message(String message) {
	}

}

import org.springframework.security.oauth2.client.web.client.RequestAttributeClientRegistrationIdResolver.clientRegistrationId
import org.springframework.security.oauth2.client.web.client.RequestAttributePrincipalResolver.principal
import org.springframework.web.client.body

@RestController
class MessagesController(private val restClient: RestClient) {

	@GetMapping("/messages")
	fun messages(): ResponseEntity<List<Message>> {
		val messages = restClient.get()
			.uri("http://localhost:8090/messages")
			.attributes(clientRegistrationId("my-oauth2-client"))
			.attributes(principal("my-application"))
			.retrieve()
			.body<Array<Message>>()!!
			.toList()
		return ResponseEntity.ok(messages)
	}

	data class Message(val message: String)

}

如上例所示，通过属性指定主体名称时，将只有一个访问Tokens，并且它将用于所有请求。spring-doc.cadn.net.cn

启用延期授权类型

常见用例涉及启用和/或配置扩展授权类型。例如，Spring Security 为jwt-bearer和token-exchangegrant 类型，但默认情况下不会启用它们，因为它们不是核心 OAuth 2.0 规范的一部分。spring-doc.cadn.net.cn

在 Spring Security 6.2 及更高版本中，我们可以简单地为一个或多个 Bean 发布一个 BeanOAuth2AuthorizedClientProvider它们将被自动拾取。以下示例只是启用jwt-bearer赠款类型：spring-doc.cadn.net.cn

使jwt-bearer赠款类型

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
public class SecurityConfig {

	@Bean
	public OAuth2AuthorizedClientProvider jwtBearer() {
		return new JwtBearerOAuth2AuthorizedClientProvider();
	}

}

@Configuration
class SecurityConfig {

	@Bean
	fun jwtBearer(): OAuth2AuthorizedClientProvider {
		return JwtBearerOAuth2AuthorizedClientProvider()
	}

}

默认OAuth2AuthorizedClientManager如果尚未提供，则将由 Spring Security 自动发布。spring-doc.cadn.net.cn

任何自定义OAuth2AuthorizedClientProvider豆子也将被拾取并应用于提供的OAuth2AuthorizedClientManager在默认授权类型之后。spring-doc.cadn.net.cn

为了在 Spring Security 6.2 之前实现上述配置，我们必须自己发布此 bean，并确保我们也重新启用了默认授权类型。要了解幕后配置的内容，配置可能如下所示：spring-doc.cadn.net.cn

使jwt-bearer授权类型（6.2 之前）

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
public class SecurityConfig {

	@Bean
	public OAuth2AuthorizedClientManager authorizedClientManager(
			ClientRegistrationRepository clientRegistrationRepository,
			OAuth2AuthorizedClientRepository authorizedClientRepository) {

		OAuth2AuthorizedClientProvider authorizedClientProvider =
			OAuth2AuthorizedClientProviderBuilder.builder()
				.authorizationCode()
				.refreshToken()
				.clientCredentials()
				.provider(new JwtBearerOAuth2AuthorizedClientProvider())
				.build();

		DefaultOAuth2AuthorizedClientManager authorizedClientManager =
			new DefaultOAuth2AuthorizedClientManager(
				clientRegistrationRepository, authorizedClientRepository);
		authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);

		return authorizedClientManager;
	}

}

@Configuration
class SecurityConfig {

	@Bean
	fun authorizedClientManager(
		clientRegistrationRepository: ClientRegistrationRepository,
		authorizedClientRepository: OAuth2AuthorizedClientRepository
	): OAuth2AuthorizedClientManager {
		val authorizedClientProvider = OAuth2AuthorizedClientProviderBuilder.builder()
			.authorizationCode()
			.refreshToken()
			.clientCredentials()
			.provider(JwtBearerOAuth2AuthorizedClientProvider())
			.build()

		val authorizedClientManager = DefaultOAuth2AuthorizedClientManager(
			clientRegistrationRepository, authorizedClientRepository
		)
		authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider)

		return authorizedClientManager
	}

}

自定义现有授权类型

通过发布 Bean 启用扩展授权类型的功能还提供了自定义现有授权类型的机会，而无需重新定义默认值。例如，如果我们想自定义OAuth2AuthorizedClientProvider对于client_credentialsgrant，我们可以简单地发布一个 bean，如下所示：spring-doc.cadn.net.cn

自定义客户端凭据授权类型

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
public class SecurityConfig {

	@Bean
	public OAuth2AuthorizedClientProvider clientCredentials() {
		ClientCredentialsOAuth2AuthorizedClientProvider authorizedClientProvider =
				new ClientCredentialsOAuth2AuthorizedClientProvider();
		authorizedClientProvider.setClockSkew(Duration.ofMinutes(5));

		return authorizedClientProvider;
	}

}

@Configuration
class SecurityConfig {

	@Bean
	fun clientCredentials(): OAuth2AuthorizedClientProvider {
		val authorizedClientProvider = ClientCredentialsOAuth2AuthorizedClientProvider()
		authorizedClientProvider.setClockSkew(Duration.ofMinutes(5))
		return authorizedClientProvider
	}

}

自定义Tokens请求参数

在获取访问Tokens时需要自定义请求参数是相当普遍的。例如，假设我们要添加自定义audience参数添加到Tokens请求，因为提供程序需要此参数才能用于authorization_code授予。spring-doc.cadn.net.cn

在 Spring Security 6.2 及更高版本中，我们可以简单地发布一个类型为OAuth2AccessTokenResponseClient替换为 generic 类型OAuth2AuthorizationCodeGrantRequestSpring Security 将使用它来配置 OAuth2 客户端组件。spring-doc.cadn.net.cn

以下示例自定义了authorization_code没有 DSL 的授权：spring-doc.cadn.net.cn

自定义授权码授予的Tokens请求参数

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
public class SecurityConfig {

	@Bean
	public OAuth2AccessTokenResponseClient<OAuth2AuthorizationCodeGrantRequest> authorizationCodeAccessTokenResponseClient() {
		RestClientAuthorizationCodeTokenResponseClient accessTokenResponseClient =
			new RestClientAuthorizationCodeTokenResponseClient();
		accessTokenResponseClient.addParametersConverter(parametersConverter());

		return accessTokenResponseClient;
	}

	private static Converter<OAuth2AuthorizationCodeGrantRequest, MultiValueMap<String, String>> parametersConverter() {
		return (grantRequest) -> {
			MultiValueMap<String, String> parameters = new LinkedMultiValueMap<>();
			parameters.set("audience", "xyz_value");

			return parameters;
		};
	}

}

@Configuration
class SecurityConfig {

	@Bean
	fun authorizationCodeAccessTokenResponseClient(): OAuth2AccessTokenResponseClient<OAuth2AuthorizationCodeGrantRequest> {
		val accessTokenResponseClient = RestClientAuthorizationCodeTokenResponseClient()
		accessTokenResponseClient.addParametersConverter(parametersConverter())

		return accessTokenResponseClient
	}

	private fun parametersConverter(): Converter<OAuth2AuthorizationCodeGrantRequest, MultiValueMap<String, String>> {
		return Converter<OAuth2AuthorizationCodeGrantRequest, MultiValueMap<String, String>> { grantRequest ->
			LinkedMultiValueMap<String, String>().also { parameters ->
				parameters["audience"] = "xyz_value"
			}
		}
	}

}

请注意，我们不需要自定义SecurityFilterChainbean 的，并且可以坚持使用默认值。如果使用 Spring Boot 而不进行额外的自定义，我们实际上可以省略SecurityFilterChain豆子。spring-doc.cadn.net.cn

在 Spring Security 6.2 之前，我们必须确保此自定义适用于使用 Spring Security DSL 的 OAuth2 登录（如果我们使用此功能）和 OAuth2 客户端组件。要了解幕后配置的内容，配置可能如下所示：spring-doc.cadn.net.cn

自定义授权码授予的Tokens请求参数（6.2 之前）

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
@EnableWebSecurity
public class SecurityConfig {

	@Bean
	public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
		RestClientAuthorizationCodeTokenResponseClient accessTokenResponseClient =
			new RestClientAuthorizationCodeTokenResponseClient();
		accessTokenResponseClient.addParametersConverter(parametersConverter());

		http
			.authorizeHttpRequests((authorize) -> authorize
				.anyRequest().authenticated()
			)
			.oauth2Login((oauth2Login) -> oauth2Login
				.tokenEndpoint((tokenEndpoint) -> tokenEndpoint
					.accessTokenResponseClient(accessTokenResponseClient)
				)
			)
			.oauth2Client((oauth2Client) -> oauth2Client
				.authorizationCodeGrant((authorizationCode) -> authorizationCode
					.accessTokenResponseClient(accessTokenResponseClient)
				)
			);

		return http.build();
	}

	private static Converter<OAuth2AuthorizationCodeGrantRequest, MultiValueMap<String, String>> parametersConverter() {
		// ...
	}

}

import org.springframework.security.config.annotation.web.invoke

@Configuration
@EnableWebSecurity
class SecurityConfig {

	@Bean
	fun securityFilterChain(http: HttpSecurity): SecurityFilterChain {
		val tokenResponseClient = RestClientAuthorizationCodeTokenResponseClient()
		tokenResponseClient.addParametersConverter(parametersConverter())

		http {
			authorizeHttpRequests {
				authorize(anyRequest, authenticated)
			}
			oauth2Login {
				tokenEndpoint {
					accessTokenResponseClient = tokenResponseClient
				}
			}
			oauth2Client {
				authorizationCodeGrant {
					accessTokenResponseClient = tokenResponseClient
				}
			}
		}

		return http.build()
	}

	private fun parametersConverter(): Converter<OAuth2AuthorizationCodeGrantRequest, MultiValueMap<String, String>> {
		// ...
	}

}

对于其他赠款类型，我们可以发布额外的OAuth2AccessTokenResponseClientbean 来覆盖默认值。例如，要自定义client_credentials授予我们可以发布以下 bean：spring-doc.cadn.net.cn

自定义客户端凭证授予的Tokens请求参数

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
public class SecurityConfig {

	@Bean
	public OAuth2AccessTokenResponseClient<OAuth2ClientCredentialsGrantRequest> clientCredentialsAccessTokenResponseClient() {
		RestClientClientCredentialsTokenResponseClient accessTokenResponseClient =
				new RestClientClientCredentialsTokenResponseClient();
		accessTokenResponseClient.addParametersConverter(parametersConverter());

		return accessTokenResponseClient;
	}

	private static Converter<OAuth2ClientCredentialsGrantRequest, MultiValueMap<String, String>> parametersConverter() {
		// ...
	}

}

@Configuration
class SecurityConfig {

	@Bean
	fun clientCredentialsAccessTokenResponseClient(): OAuth2AccessTokenResponseClient<OAuth2ClientCredentialsGrantRequest> {
		val accessTokenResponseClient = RestClientClientCredentialsTokenResponseClient()
		accessTokenResponseClient.addParametersConverter(parametersConverter())

		return accessTokenResponseClient
	}

	private fun parametersConverter(): Converter<OAuth2ClientCredentialsGrantRequest, MultiValueMap<String, String>> {
		// ...
	}

}

Spring Security 会自动解析以下泛型类型的OAuth2AccessTokenResponseClient豆：spring-doc.cadn.net.cn

OAuth2AuthorizationCodeGrantRequest（参见RestClientAuthorizationCodeTokenResponseClient)spring-doc.cadn.net.cn
OAuth2RefreshTokenGrantRequest（参见RestClientRefreshTokenTokenResponseClient)spring-doc.cadn.net.cn
OAuth2ClientCredentialsGrantRequest（参见RestClientClientCredentialsTokenResponseClient)spring-doc.cadn.net.cn
JwtBearerGrantRequest（参见RestClientJwtBearerTokenResponseClient)spring-doc.cadn.net.cn
TokenExchangeGrantRequest（参见RestClientTokenExchangeTokenResponseClient)spring-doc.cadn.net.cn

发布类型为OAuth2AccessTokenResponseClient<JwtBearerGrantRequest>将自动启用jwt-bearer授权类型，无需单独配置。spring-doc.cadn.net.cn

发布类型为OAuth2AccessTokenResponseClient<TokenExchangeGrantRequest>将自动启用token-exchange授权类型，无需单独配置。spring-doc.cadn.net.cn

自定义`RestClient`由 OAuth2 客户端组件使用

另一个常见用例是需要自定义RestClient获取访问Tokens时使用。我们可能需要这样做来自定义响应的处理（通过自定义HttpMessageConverter）或为公司网络应用代理设置（通过自定义的ClientHttpRequestFactory).spring-doc.cadn.net.cn

在 Spring Security 6.2 及更高版本中，我们可以简单地发布类型为OAuth2AccessTokenResponseClientSpring Security 将配置并发布一个OAuth2AuthorizedClientManager豆子。spring-doc.cadn.net.cn

以下示例自定义RestClient对于所有受支持的授权类型：spring-doc.cadn.net.cn

自定义RestClient对于 OAuth2 客户端

Javaspring-doc.cadn.net.cn
Kotlinspring-doc.cadn.net.cn

@Configuration
public class SecurityConfig {

	@Bean
	public OAuth2AccessTokenResponseClient<OAuth2AuthorizationCodeGrantRequest> authorizationCodeAccessTokenResponseClient() {
		RestClientAuthorizationCodeTokenResponseClient accessTokenResponseClient =
			new RestClientAuthorizationCodeTokenResponseClient();
		accessTokenResponseClient.setRestClient(restClient());

		return accessTokenResponseClient;
	}

	@Bean
	public OAuth2AccessTokenResponseClient<OAuth2RefreshTokenGrantRequest> refreshTokenAccessTokenResponseClient() {
		RestClientRefreshTokenTokenResponseClient accessTokenResponseClient =
			new RestClientRefreshTokenTokenResponseClient();
		accessTokenResponseClient.setRestClient(restClient());

		return accessTokenResponseClient;
	}

	@Bean
	public OAuth2AccessTokenResponseClient<OAuth2ClientCredentialsGrantRequest> clientCredentialsAccessTokenResponseClient() {
		RestClientClientCredentialsTokenResponseClient accessTokenResponseClient =
			new RestClientClientCredentialsTokenResponseClient();
		accessTokenResponseClient.setRestClient(restClient());

		return accessTokenResponseClient;
	}

	@Bean
	public OAuth2AccessTokenResponseClient<JwtBearerGrantRequest> jwtBearerAccessTokenResponseClient() {
		RestClientJwtBearerTokenResponseClient accessTokenResponseClient =
			new RestClientJwtBearerTokenResponseClient();
		accessTokenResponseClient.setRestClient(restClient());

		return accessTokenResponseClient;
	}

	@Bean
	public OAuth2AccessTokenResponseClient<TokenExchangeGrantRequest> tokenExchangeAccessTokenResponseClient() {
		RestClientTokenExchangeTokenResponseClient accessTokenResponseClient =
			new RestClientTokenExchangeTokenResponseClient();
		accessTokenResponseClient.setRestClient(restClient());

		return accessTokenResponseClient;
	}

	@Bean
	public RestClient restClient() {
		// ...
	}

}

@Configuration
class SecurityConfig {

	@Bean
	fun authorizationCodeAccessTokenResponseClient(): OAuth2AccessTokenResponseClient<OAuth2AuthorizationCodeGrantRequest> {
		val accessTokenResponseClient = RestClientAuthorizationCodeTokenResponseClient()
		accessTokenResponseClient.setRestClient(restClient())

		return accessTokenResponseClient
	}

	@Bean
	fun refreshTokenAccessTokenResponseClient(): OAuth2AccessTokenResponseClient<OAuth2RefreshTokenGrantRequest> {
		val accessTokenResponseClient = RestClientRefreshTokenTokenResponseClient()
		accessTokenResponseClient.setRestClient(restClient())

		return accessTokenResponseClient
	}

	@Bean
	fun clientCredentialsAccessTokenResponseClient(): OAuth2AccessTokenResponseClient<OAuth2ClientCredentialsGrantRequest> {
		val accessTokenResponseClient = RestClientClientCredentialsTokenResponseClient()
		accessTokenResponseClient.setRestClient(restClient())

		return accessTokenResponseClient
	}

	@Bean
	fun jwtBearerAccessTokenResponseClient(): OAuth2AccessTokenResponseClient<JwtBearerGrantRequest> {
		val accessTokenResponseClient = RestClientJwtBearerTokenResponseClient()
		accessTokenResponseClient.setRestClient(restClient())

		return accessTokenResponseClient
	}

	@Bean
	fun tokenExchangeAccessTokenResponseClient(): OAuth2AccessTokenResponseClient<TokenExchangeGrantRequest> {
		val accessTokenResponseClient = RestClientTokenExchangeTokenResponseClient()
		accessTokenResponseClient.setRestClient(restClient())

		return accessTokenResponseClient
	}

	@Bean
	fun restClient(): RestClient {
		// ...
	}

}

默认OAuth2AuthorizedClientManager如果尚未提供，则将由 Spring Security 自动发布。spring-doc.cadn.net.cn

在 Spring Security 6.2 之前，我们必须确保将此自定义应用于 OAuth2 登录（如果我们使用此功能）和 OAuth2 客户端组件。我们必须同时使用 Spring Security DSL（对于authorization_codegrant）并发布类型为OAuth2AuthorizedClientManager对于其他赠款类型。要了解幕后配置的内容，配置可能如下所示：spring-doc.cadn.net.cn
