如何使用OAuth2AuthorizedClientManager与OAuth2AuthorizedClientService

我使用springsecurity5在springboot2中实现OAuth2客户机。我不知道该怎么用 OAuth2AuthorizedClientManager 与 OAuth2AuthorizedClientService . OAuth2AuthorizedClientManger是在5.2中引入的,因此它是一个较新的API,但是OAuth2AuthorizedClientService看起来更像是一个更精致的客户端接口。我预料到了 OAuthe2AuthorizedClientService 可以配置 OAuth2AuthorizedClientManager 但事实似乎并非如此。

重要的是,我需要定制 OAuth2AccessTokenResponseHttpMessageConverter 发送到自定义服务器的授权请求。可以在 OAuth2AuthorizedClient Manager 但我不知道该怎么做 OAuthe2授权客户端服务 .

  @Bean
  public OAuth2AuthorizedClientManager authorizedClientManager(ClientRegistrationRepository clientRegistrationRepository,
                                                               OAuth2AuthorizedClientService oAuth2AuthorizedClientService) {

    DefaultClientCredentialsTokenResponseClient defaultClientCredentialsTokenResponseClient = new DefaultClientCredentialsTokenResponseClient();
    defaultClientCredentialsTokenResponseClient.setRequestEntityConverter(new OAuth2ClientCredentialsGrantJWTAssertionRequestEntityConverter());
    OAuth2AuthorizedClientProvider authorizedClientProvider =
        OAuth2AuthorizedClientProviderBuilder.builder()
          .clientCredentials(clientCredentialsGrantBuilder -> {

            clientCredentialsGrantBuilder.accessTokenResponseClient(defaultClientCredentialsTokenResponseClient);
          })
          .build();
    OAuth2AuthorizedClientManager authorizedClientManager
        = new AuthorizedClientServiceOAuth2AuthorizedClientManager(clientRegistrationRepository, oAuth2AuthorizedClientService);
    ((AuthorizedClientServiceOAuth2AuthorizedClientManager)authorizedClientManager).setAuthorizedClientProvider(authorizedClientProvider);
    return authorizedClientManager;
  }
