The OAuth 2.0 Client features provide support for the Client role as defined in the OAuth 2.0 Authorization Framework.
At a high-level, the core features available are:
- 
WebClientintegration for Servlet Environments (for requesting protected resources)
The HttpSecurity.oauth2Client() DSL provides a number of configuration options for customizing the core components used by OAuth 2.0 Client.
In addition, HttpSecurity.oauth2Client().authorizationCodeGrant() enables the customization of the Authorization Code grant.
The following code shows the complete configuration options provided by the HttpSecurity.oauth2Client() DSL:
- 
Java 
- 
Kotlin 
@Configuration
@EnableWebSecurity
public class OAuth2ClientSecurityConfig {
	@Bean
	public SecurityFilterChain filterChain(HttpSecurity http) throws Exception {
		http
			.oauth2Client(oauth2 -> oauth2
				.clientRegistrationRepository(this.clientRegistrationRepository())
				.authorizedClientRepository(this.authorizedClientRepository())
				.authorizedClientService(this.authorizedClientService())
				.authorizationCodeGrant(codeGrant -> codeGrant
					.authorizationRequestRepository(this.authorizationRequestRepository())
					.authorizationRequestResolver(this.authorizationRequestResolver())
					.accessTokenResponseClient(this.accessTokenResponseClient())
				)
			);
		return http.build();
	}
}@Configuration
@EnableWebSecurity
class OAuth2ClientSecurityConfig {
    @Bean
    open fun filterChain(http: HttpSecurity): SecurityFilterChain {
        http {
            oauth2Client {
                clientRegistrationRepository = clientRegistrationRepository()
                authorizedClientRepository = authorizedClientRepository()
                authorizedClientService = authorizedClientService()
                authorizationCodeGrant {
                    authorizationRequestRepository = authorizationRequestRepository()
                    authorizationRequestResolver = authorizationRequestResolver()
                    accessTokenResponseClient = accessTokenResponseClient()
                }
            }
        }
        return http.build()
    }
}In addition to the HttpSecurity.oauth2Client() DSL, XML configuration is also supported.
The following code shows the complete configuration options available in the security namespace:
<http>
	<oauth2-client client-registration-repository-ref="clientRegistrationRepository"
				   authorized-client-repository-ref="authorizedClientRepository"
				   authorized-client-service-ref="authorizedClientService">
		<authorization-code-grant
				authorization-request-repository-ref="authorizationRequestRepository"
				authorization-request-resolver-ref="authorizationRequestResolver"
				access-token-response-client-ref="accessTokenResponseClient"/>
	</oauth2-client>
</http>The OAuth2AuthorizedClientManager is responsible for managing the authorization (or re-authorization) of an OAuth 2.0 Client, in collaboration with one or more OAuth2AuthorizedClientProvider(s).
The following code shows an example of how to register an OAuth2AuthorizedClientManager @Bean and associate it with an OAuth2AuthorizedClientProvider composite that provides support for the authorization_code, refresh_token, client_credentials, and password authorization grant types:
- 
Java 
- 
Kotlin 
@Bean
public OAuth2AuthorizedClientManager authorizedClientManager(
		ClientRegistrationRepository clientRegistrationRepository,
		OAuth2AuthorizedClientRepository authorizedClientRepository) {
	OAuth2AuthorizedClientProvider authorizedClientProvider =
			OAuth2AuthorizedClientProviderBuilder.builder()
					.authorizationCode()
					.refreshToken()
					.clientCredentials()
					.password()
					.build();
	DefaultOAuth2AuthorizedClientManager authorizedClientManager =
			new DefaultOAuth2AuthorizedClientManager(
					clientRegistrationRepository, authorizedClientRepository);
	authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider);
	return authorizedClientManager;
}@Bean
fun authorizedClientManager(
        clientRegistrationRepository: ClientRegistrationRepository,
        authorizedClientRepository: OAuth2AuthorizedClientRepository): OAuth2AuthorizedClientManager {
    val authorizedClientProvider: OAuth2AuthorizedClientProvider = OAuth2AuthorizedClientProviderBuilder.builder()
            .authorizationCode()
            .refreshToken()
            .clientCredentials()
            .password()
            .build()
    val authorizedClientManager = DefaultOAuth2AuthorizedClientManager(
            clientRegistrationRepository, authorizedClientRepository)
    authorizedClientManager.setAuthorizedClientProvider(authorizedClientProvider)
    return authorizedClientManager
}
