核心配置

Spring Boot 2.x 示例

Spring Boot 2.x 为 OAuth 2.0 登录带来了完整的自动配置功能。spring-doc.cadn.net.cn

本节介绍如何使用 Google 作为身份验证提供程序来配置 OAuth 2.0 登录示例，并涵盖以下主题：spring-doc.cadn.net.cn

初始设置

要使用 Google 的 OAuth 2.0 身份验证系统进行登录，您必须在 Google API 控制台中设置一个项目来获取 OAuth 2.0 凭据。spring-doc.cadn.net.cn

Google 用于身份验证的 OAuth 2.0 实现符合 OpenID Connect 1.0 规范，并通过了 OpenID 认证。spring-doc.cadn.net.cn

按照 OpenID Connect 页面上的说明进行作，从“设置 OAuth 2.0”部分开始。spring-doc.cadn.net.cn

完成“获取 OAuth 2.0 凭据”说明后，您应该拥有新的 OAuth 客户端，其凭据由客户端 ID 和客户端密码组成。spring-doc.cadn.net.cn

设置重定向 URI

重定向 URI 是最终用户的用户代理在向 Google 进行身份验证并在“同意”页面上授予对 OAuth 客户端（在上一步中创建）的访问权限后，重定向回应用程序中的路径。spring-doc.cadn.net.cn

在“设置重定向 URI”小节中，确保将授权重定向 URI 字段设置为localhost:8080/login/oauth2/code/google.spring-doc.cadn.net.cn

默认重定向 URI 模板为{baseUrl}/login/oauth2/code/{registrationId}. 这registrationId是ClientRegistration.spring-doc.cadn.net.cn

如果 OAuth 客户端在代理服务器后面运行，则应检查代理服务器配置以确保应用程序配置正确。此外，请参阅支持 URI模板变量为redirect-uri.spring-doc.cadn.net.cn

配置application.yml

现在，您已拥有 Google 的新 OAuth 客户端，您需要将应用配置为将 OAuth 客户端用于身份验证流程。为此，请执行以下作：spring-doc.cadn.net.cn

  1. 转到application.yml并设置以下配置：spring-doc.cadn.net.cn

    spring:
  security:
    oauth2:
      client:
        registration:	(1)
          google:	(2)
            client-id: google-client-id
            client-secret: google-client-secret
    OAuth 客户端属性
    1 spring.security.oauth2.client.registration是 OAuth 客户端属性的基本属性前缀。
    2 基本属性前缀后面是ClientRegistration，例如谷歌。

  2. 替换client-id和client-secret属性，并包含您之前创建的 OAuth 2.0 凭据。spring-doc.cadn.net.cn

启动应用程序

启动 Spring Boot 2.x 示例并转到localhost:8080. 然后，您将被重定向到默认的自动生成登录页面，该页面显示 Google 的链接。spring-doc.cadn.net.cn

单击 Google 链接，然后您将被重定向到 Google 进行身份验证。spring-doc.cadn.net.cn

使用您的 Google 帐户凭据进行身份验证后，您会看到同意屏幕。 同意屏幕会要求您允许或拒绝访问您之前创建的 OAuth 客户端。 单击“允许”以授权 OAuth 客户端访问您的电子邮件地址和基本配置文件信息。spring-doc.cadn.net.cn

此时，OAuth 客户端会从 UserInfo 端点检索您的电子邮件地址和基本配置文件信息，并建立经过身份验证的会话。spring-doc.cadn.net.cn

Spring Boot 2.x 属性映射

下表概述了 Spring Boot 2.x OAuth 客户端属性到 ClientRegistration 属性的映射。spring-doc.cadn.net.cn

spring.security.oauth2.client.provider.[providerId].user-name-attributespring-doc.cadn.net.cn

providerDetails.userInfoEndpoint.userNameAttributeNamespring-doc.cadn.net.cn

最初可以配置ClientRegistration通过使用发现 OpenID Connect 提供程序的配置端点或授权服务器的元数据端点，通过指定spring.security.oauth2.client.provider.[providerId].issuer-uri财产。spring-doc.cadn.net.cn

CommonOAuth2提供程序

CommonOAuth2Provider为许多知名提供商预定义了一组默认客户端属性：Google、GitHub、Facebook 和 Okta。spring-doc.cadn.net.cn

例如，authorization-uri,token-uri和user-info-uri对于提供者，不要经常更改。 因此，提供默认值以减少所需的配置是有意义的。spring-doc.cadn.net.cn

如前所述，当我们配置 Google 客户端时，只有client-id和client-secret属性是必需的。spring-doc.cadn.net.cn

以下列表显示了一个示例：spring-doc.cadn.net.cn

spring:
  security:
    oauth2:
      client:
        registration:
          google:
            client-id: google-client-id
            client-secret: google-client-secret
客户端属性的自动默认值在这里无缝工作，因为registrationId (google） 匹配GOOGLE enum（不区分大小写）在CommonOAuth2Provider.

对于您可能想要指定不同的registrationId如google-login，您仍然可以通过配置provider财产。spring-doc.cadn.net.cn

以下列表显示了一个示例：spring-doc.cadn.net.cn

spring:
  security:
    oauth2:
      client:
        registration:
          google-login:	(1)
            provider: google	(2)
            client-id: google-client-id
            client-secret: google-client-secret
1 这registrationId设置为google-login.
2 这provider属性设置为google，这将利用在CommonOAuth2Provider.GOOGLE.getBuilder().

配置自定义提供程序属性

有一些 OAuth 2.0 提供程序支持多租户，这会导致每个租户（或子域）的协议端点不同。spring-doc.cadn.net.cn

例如，在 Okta 注册的 OAuth 客户端被分配给特定的子域，并具有自己的协议端点。spring-doc.cadn.net.cn

对于这些情况，Spring Boot 2.x 提供了以下基本属性来配置自定义提供程序属性：spring.security.oauth2.client.provider.[providerId].spring-doc.cadn.net.cn

以下列表显示了一个示例：spring-doc.cadn.net.cn

spring:
  security:
    oauth2:
      client:
        registration:
          okta:
            client-id: okta-client-id
            client-secret: okta-client-secret
        provider:
          okta:	(1)
            authorization-uri: https://your-subdomain.oktapreview.com/oauth2/v1/authorize
            token-uri: https://your-subdomain.oktapreview.com/oauth2/v1/token
            user-info-uri: https://your-subdomain.oktapreview.com/oauth2/v1/userinfo
            user-name-attribute: sub
            jwk-set-uri: https://your-subdomain.oktapreview.com/oauth2/v1/keys
1 基本属性 （spring.security.oauth2.client.provider.okta） 允许自定义配置协议端点位置。

覆盖 Spring Boot 2.x 自动配置

用于 OAuth 客户端支持的 Spring Boot 2.x 自动配置类是OAuth2ClientAutoConfiguration.spring-doc.cadn.net.cn

它执行以下任务：spring-doc.cadn.net.cn

  • 注册一个ClientRegistrationRepository @Bean由ClientRegistration（s） 来自配置的 OAuth 客户端属性。spring-doc.cadn.net.cn

  • 注册一个SecurityFilterChain @Bean并通过httpSecurity.oauth2Login().spring-doc.cadn.net.cn

如果您需要根据您的特定要求覆盖自动配置，您可以通过以下方式执行此作：spring-doc.cadn.net.cn

注册 ClientRegistrationRepository @Bean

以下示例演示如何注册ClientRegistrationRepository @Bean:spring-doc.cadn.net.cn

@Configuration
public class OAuth2LoginConfig {

	@Bean
	public ClientRegistrationRepository clientRegistrationRepository() {
		return new InMemoryClientRegistrationRepository(this.googleClientRegistration());
	}

	private ClientRegistration googleClientRegistration() {
		return ClientRegistration.withRegistrationId("google")
			.clientId("google-client-id")
			.clientSecret("google-client-secret")
			.clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
			.authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
			.redirectUri("{baseUrl}/login/oauth2/code/{registrationId}")
			.scope("openid", "profile", "email", "address", "phone")
			.authorizationUri("https://accounts.google.com/o/oauth2/v2/auth")
			.tokenUri("https://www.googleapis.com/oauth2/v4/token")
			.userInfoUri("https://www.googleapis.com/oauth2/v3/userinfo")
			.userNameAttributeName(IdTokenClaimNames.SUB)
			.jwkSetUri("https://www.googleapis.com/oauth2/v3/certs")
			.clientName("Google")
			.build();
	}
}
@Configuration
class OAuth2LoginConfig {
    @Bean
    fun clientRegistrationRepository(): ClientRegistrationRepository {
        return InMemoryClientRegistrationRepository(googleClientRegistration())
    }

    private fun googleClientRegistration(): ClientRegistration {
        return ClientRegistration.withRegistrationId("google")
                .clientId("google-client-id")
                .clientSecret("google-client-secret")
                .clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
                .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
                .redirectUri("{baseUrl}/login/oauth2/code/{registrationId}")
                .scope("openid", "profile", "email", "address", "phone")
                .authorizationUri("https://accounts.google.com/o/oauth2/v2/auth")
                .tokenUri("https://www.googleapis.com/oauth2/v4/token")
                .userInfoUri("https://www.googleapis.com/oauth2/v3/userinfo")
                .userNameAttributeName(IdTokenClaimNames.SUB)
                .jwkSetUri("https://www.googleapis.com/oauth2/v3/certs")
                .clientName("Google")
                .build()
    }
}

注册 SecurityFilterChain @Bean

以下示例演示如何注册SecurityFilterChain @Bean跟@EnableWebSecurity并通过启用 OAuth 2.0 登录httpSecurity.oauth2Login():spring-doc.cadn.net.cn

OAuth2 登录配置
@Configuration
@EnableWebSecurity
public class OAuth2LoginSecurityConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			.authorizeHttpRequests(authorize -> authorize
				.anyRequest().authenticated()
			)
			.oauth2Login(withDefaults());
		return http.build();
	}
}
@Configuration
@EnableWebSecurity
class OAuth2LoginSecurityConfig {

    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            authorizeRequests {
                authorize(anyRequest, authenticated)
            }
            oauth2Login { }
        }
        return http.build()
    }
}

完全覆盖自动配置

以下示例演示如何通过注册ClientRegistrationRepository @Bean和SecurityFilterChain @Bean.spring-doc.cadn.net.cn

覆盖自动配置
@Configuration
public class OAuth2LoginConfig {

	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {

        return InMemoryClientRegistrationRepository(googleClientRegistration())
    }

    private fun googleClientRegistration(): ClientRegistration {
        return ClientRegistration.withRegistrationId("google")
                .clientId("google-client-id")
                .clientSecret("google-client-secret")
                .clientAuthenticationMethod(ClientAuthenticationMethod.CLIENT_SECRET_BASIC)
                .authorizationGrantType(AuthorizationGrantType.AUTHORIZATION_CODE)
                .redirectUri("{baseUrl}/login/oauth2/code/{registrationId}")
                .scope("openid", "profile", "email", "address", "phone")
                .authorizationUri("https://accounts.google.com/o/oauth2/v2/auth")

                .clientName("Google")
                .build()
    }
}
