Feign client - timeout configuration

Spring Cloud in Feign client is enabled by default to support the Ribbon, the most important is the two time-out connection timeout ConnectTimeout and read timeout ReadTimeout , by default, that is, without any configuration, Feign timeout will be overwritten Ribbon, two time-out time is 1 second.

Simply put a scene here, not on the code, app-user service calls app-order service interface, and then set the delay 1.5s in the app-order interface, the call to see the effect:

Wrong call, the console display read timeout, this is because Ribbon default timeout is 1s caused. As long as we look at this configuration timeout on the line:

Ribbon Global Configuration

Add yml configuration profile of the caller, set the timeout to 5s:

ribbon:
  #建立连接超时时间
  ConnectTimeout: 5000
  #建立连接之后，读取响应资源超时时间
  ReadTimeout: 5000

 Then restart the service, the call is successful

 

 Feign Configuration

Note: Feign configuration takes precedence over the Ribbon configuration. The same effect Once you've configured.

feign:
  client:
    config:
      #这里填具体的服务名称（也可以填default，表示对所有服务生效）
      app-order:
        #connectTimeout和readTimeout这两个得一起配置才会生效
        connectTimeout: 5000
        readTimeout: 5000
