java - Spring Boot OAuth 资源服务器代理配置

Question

我目前正在努力将代理与 Spring-Webflux 结合使用。在其他服务中，我总是遵循这种方法，效果非常好(代理配置是从标准环境变量中检索的):

@Bean
public RestTemplate restTemplate() {
    final RestTemplate restTemplate = new RestTemplate();
    final CloseableHttpClient client = HttpClientBuilder.create().useSystemProperties().build();
    restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory(client));
    return restTemplate;
  }

但现在我尝试使用 Spring Oauth-Resource-Server 包设置 OAuth-Ressource-Server。该包使用 HTTP(S) 的 Spring-Webflux。该服务现在尝试从给定的 uri(需要代理)获取 jwk-set，但由于连接拒绝错误而失败。有人得到了 Spring-Webflux/OAuth-Ressource 和代理的组合吗？

我自己发现，提供一个带有正确配置的 webclient 的 NimbusReactiveJwtDecoder bean 可以解决这个问题。

import lombok.Data;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.http.client.reactive.ReactorClientHttpConnector;
import org.springframework.security.oauth2.jwt.NimbusReactiveJwtDecoder;
import org.springframework.stereotype.Component;
import org.springframework.web.reactive.function.client.WebClient;
import reactor.netty.http.client.HttpClient;
import reactor.netty.tcp.ProxyProvider;

@Data
@Component
@Configuration
@ConfigurationProperties(value = "proxy")
public class ProxyConfig {

  private String host;
  private int port;
  private String username;
  private String password;

  @Value("${spring.security.oauth2.resourceserver.jwt.jwk-set-uri}")
  private String jwkSetUri;

  @Bean
  public WebClient webClient(ReactorClientHttpConnector reactorClientHttpConnector) {
    return WebClient.builder().clientConnector(reactorClientHttpConnector).build();
  }

  @Bean
  public HttpClient httpClient() {
    return HttpClient.create()
        .tcpConfiguration(tcpClient ->
            tcpClient.proxy(
                proxy -> proxy.type(ProxyProvider.Proxy.HTTP).host(host)
                    .port(port).username(username)
                    .password(s -> password)));
  }

  @Bean
  ReactorClientHttpConnector reactorClientHttpConnector(HttpClient httpClient) {
    return new ReactorClientHttpConnector(httpClient);
  }

  @Bean
  public NimbusReactiveJwtDecoder nimbusReactiveJwtDecoder(WebClient webClient) {
    return NimbusReactiveJwtDecoder
        .withJwkSetUri(jwkSetUri)
        .webClient(webClient).build();
  }
}
