The OAuth 2.0 Client features provide support for the Client role as defined in the OAuth 2.0 Authorization Framework.spring-doc.cn

At a high-level, the core features available are:spring-doc.cn

Authorization Grant support
Client Authentication support
HTTP Client support

The ServerHttpSecurity.oauth2Client() DSL provides a number of configuration options for customizing the core components used by OAuth 2.0 Client.spring-doc.cn

The following code shows the complete configuration options provided by the ServerHttpSecurity.oauth2Client() DSL:spring-doc.cn

OAuth2 Client Configuration Options
@Configuration
@EnableWebFluxSecurity
public class OAuth2ClientSecurityConfig {

	@Bean
	public SecurityWebFilterChain securityWebFilterChain(ServerHttpSecurity http) {
		http
			.oauth2Client(oauth2 -> oauth2
				.clientRegistrationRepository(this.clientRegistrationRepository())
				.authorizedClientRepository(this.authorizedClientRepository())
				.authorizationRequestRepository(this.authorizationRequestRepository())
				.authorizationRequestResolver(this.authorizationRequestResolver())
				.authenticationConverter(this.authenticationConverter())
				.authenticationManager(this.authenticationManager())
			);

		return http.build();
	}
}
@Configuration
@EnableWebFluxSecurity
class OAuth2ClientSecurityConfig {

    @Bean
    fun securityFilterChain(http: ServerHttpSecurity): SecurityWebFilterChain {
        http {
            oauth2Client {
                clientRegistrationRepository = clientRegistrationRepository()
                authorizedClientRepository = authorizedClientRepository()
                authorizationRequestRepository = authorizedRequestRepository()
                authorizationRequestResolver = authorizationRequestResolver()
                authenticationConverter = authenticationConverter()
                authenticationManager = authenticationManager()

The ReactiveOAuth2AuthorizedClientManager is responsible for managing the authorization (or re-authorization) of an OAuth 2.0 Client, in collaboration with one or more ReactiveOAuth2AuthorizedClientProvider(s).spring-doc.cn

The following code shows an example of how to register a ReactiveOAuth2AuthorizedClientManager @Bean and associate it with a ReactiveOAuth2AuthorizedClientProvider composite that provides support for the authorization_code, refresh_token, client_credentials and password authorization grant types:spring-doc.cn

@Bean
public ReactiveOAuth2AuthorizedClientManager authorizedClientManager(
		ReactiveClientRegistrationRepository clientRegistrationRepository,
		ServerOAuth2AuthorizedClientRepository authorizedClientRepository) {

	ReactiveOAuth2AuthorizedClientProvider authorizedClientProvider =
			ReactiveOAuth2AuthorizedClientProviderBuilder.builder()
					.authorizationCode()
					.refreshToken()
					.clientCredentials()
					.password()
					.build();

	DefaultReactiveOAuth2AuthorizedClientManager authorizedClientManager =
			new DefaultReactiveOAuth2AuthorizedClientManager(
					clientRegistrationRepository, authorizedClientRepository);
	authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);

	return authorizedClientManager;
}
@Bean
fun authorizedClientManager(
        clientRegistrationRepository: ReactiveClientRegistrationRepository,
        authorizedClientRepository: ServerOAuth2AuthorizedClientRepository): ReactiveOAuth2AuthorizedClientManager {
    val authorizedClientProvider: ReactiveOAuth2AuthorizedClientProvider = ReactiveOAuth2AuthorizedClientProviderBuilder.builder()
            .authorizationCode()
            .refreshToken()
            .clientCredentials()
            .password()
            .build()
    val authorizedClientManager = DefaultReactiveOAuth2AuthorizedClientManager(
            clientRegistrationRepository, authorizedClientRepository)
    authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider)
    return authorizedClientManager
}
