springcloud之Feign超時提示Read timed out executing POST

問題描述：

Feign接口調用分兩層，Ribbon的調用和Hystrix調用，理論上設置Ribbon的時間即可，但是Ribbon的超時時間和Hystrix的超時時間需要結合起來，按照木桶原則最低的就是Feign的超時時間，建議最好配置超時時間一致.當Fegin調用時，調用的外部接口，延遲挺大，會造成Feign一直提示Read timed out executing POST

解決方法：

yml文件中如下配置即可

#hystrix的超時時間
hystrix:
    command:
        default:
            execution:
              timeout:
                enabled: true
              isolation:
                    thread:
                        #超時設置
                        timeoutInMilliseconds: 30000
ribbon:
  ReadTimeout: 30000
  #ribbon的超時時間
  ConnectTimeout: 30000

補充：

spring cloud 調用feign請求超時 feign.RetryableException: Read timed out executing POST

問題介紹：

at feign.Client$Default.execute(Client.java:74)

原因及解決辦法：

明顯可以看到是http請求報錯超時，feign的調用分兩層，ribbon的調用和hystrix的調用，高版本的hystrix默認是關閉的，所以在application.properties配置文件中設置ribbon即可

#請求處理的超時時間
ribbon.ReadTimeout: 120000
#請求連接的超時時間
ribbon.ConnectTimeout: 30000

如果開啟hystrix，hystrix的超時報錯如下圖：

FeignDemo#demo() timed-out and no fallback available。和ribbon超時報錯還是有區(qū)別的

com.netflix.hystrix.exception.HystrixRuntimeException: FeignDemo#demo() timed-out and no fallback available.

解決辦法：

feign.hystrix.enabled: true
hystrix 熔斷機制
hystrix:
  shareSecurityContext: true
  command:
    default:
      circuitBreaker:
        sleepWindowInMilliseconds: 100000
        forceClosed: true
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 600000
