SpringCloud feign、hystrix、zuul超时配置

hystrix超时配置一般需要手动配置，如果不配，接口响应稍慢就会熔断

同样，zuul也有超时配置，feign也有超时配置

zuul配置时，配置如下：

hystrix:

  command:

    default:

      execution:

        isolation:

          thread:

            timeoutInMilliseconds:60000

#zuul路由配置为serviceid时生效

ribbon:

  connectTimeout:3000

    readTimeout:20000

#zuul路由配置为url时生效

zuul:

  host:

    connect-timeout-millis:3000

    socket-timeout-millis:20000

feigh超时配置

feign:

  client:

    config:

      default:

        connectTimeout: 3000

    readTimeout: 20000

    loggerLevel: basic

PS：zuul的超时配置小于hystrix时，zuul会先超时；反之hystrix会先熔断。

 

为某个服务配置个性化的超时机制时，例如服务名称为myusers-service，配置为如下：

zuul:
  routes:
    echo:
      path: /myusers/**
      serviceId: myusers-service
      stripPrefix: true

hystrix:
  command:
    myusers-service:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: ...

myusers-service:
  ribbon:
    NIWSServerListClassName: com.netflix.loadbalancer.ConfigurationBasedServerList
    listOfServers: http://example1.com,http://example2.com
    ConnectTimeout: 1000
    ReadTimeout: 3000
    MaxTotalHttpConnections: 500
    MaxConnectionsPerHost: 100
