Spring Cloud：Zuul 断管错误

Question

我正在对由 zuul 代理服务支持的简单 spring 云应用程序进行一些压力测试，由于 Zuul 和服务之间的连接陈旧，我们偶尔会遇到管道异常异常。我用不同的配置选项配置了 Zuul，但没有成功：

hystrix:
  command:
    default:
      execution:
        isolation:
          strategy: THREAD
          thread:
            timeoutInMilliseconds: 61000


ribbon:
  ReadTimeout: 60000
  ConnectTimeout: 6000

zuul:
  host:
    socket-timeout-millis: 60000
    connect-timeout-millis: 60000

提前感谢您提供解决此问题的任何线索。例外如下：`

com.netflix.zuul.exception.ZuulException：org.springframework.cloud.netflix.zuul.filters.route.RibbonRoutingFilter.forward(RibbonRoutingFilter.java:151) ~[router.jar!/:0.0.1] 处的转发错误org.springframework.cloud.netflix.zuul.filters.route.RibbonRoutingFilter.run(RibbonRoutingFilter.java:114) ~[router.jar!/:0.0.1] at com.netflix.zuul.ZuulFilter.runFilter(ZuulFilter.java :112) ~[zuul-core-1.0.28.jar!/:na]

我遇到了同样的问题：我通过将 zuul 执行超时添加到zuul 服务器的application.yml来解决它：

# Increase the Hystrix timeout to 60s (globally)
hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 60000
