OAuth 2.0 Client

OAuth 2.0 客户端功能提供了支持，以按照 OAuth 2.0 Authorization Framework 中定义的客户端角色。

总体而言，所提供的核心特性包括：

Authorization Grant support
Client Authentication support
HTTP Client support

HttpSecurity.oauth2Client() DSL 为用于自定义 OAuth 2.0 客户端所用的核心组件提供许多配置选项。此外，HttpSecurity.oauth2Client().authorizationCodeGrant() 支持授权码授予的自定义。

以下代码展示了 HttpSecurity.oauth2Client() DSL 中提供的完整配置选项：

OAuth2 Client Configuration Options

  • 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()
    }
}

除了 HttpSecurity.oauth2Client() DSL 外，还支持 XML 配置。

以下代码显示了 security namespace 中可用的完整配置选项：

OAuth2 Client XML Configuration Options
<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>

OAuth2AuthorizedClientManager 负责管理 OAuth 2.0 客户端（或重新授权）与一个或多个 OAuth2AuthorizedClientProvider 的授权（或重新授权），

以下代码展示了注册 OAuth2AuthorizedClientManager @Bean 并将其与一个复合 @{11} 相关联的示例，该复合支持 authorization_code、refresh_token、client_credentials 和 password 授权授予类型：

  • 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
}
