我正在使用Eureka作为注册服务器，其中Zuul正在注册，我的应用程序模块cmpnyhbaseserialser已注册。

但是，当我发出POST请求时，我收到以下错误：

可能是Nikhil Pareek建议的hystrix超时或功能区超时或两者兼而有之。最佳尝试：

hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 10000
ribbon:
  ConnectTimeout: 10000
  ReadTimeout: 10000

我建议将堆栈跟踪与com.netflix.zuul.exception.ZuulException: Forwarding error while calling microservice匹配，在这种情况下，已经设置了hystrix超时。

只是增加hystrix超时

hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 10000

答案 2 :(得分：0)

请注意，功能区不再是Zuul的默认http客户端。因此，您必须添加ribbon.restclient.enabled=true才能使功能区配置生效。

  

zuul使用的默认HTTP客户端现在由Apache HTTP客户端支持，而不是已弃用的Ribbon RestClient。要使用RestClient或使用okhttp3.OkHttpClient分别设置Ribbon.restclient.enabled = true或ribbon.okhttp.enabled = true。
