Feign接口調(diào)用分兩層,Ribbon的調(diào)用和Hystrix調(diào)用,理論上設(shè)置Ribbon的時(shí)間即可,但是Ribbon的超時(shí)時(shí)間和Hystrix的超時(shí)時(shí)間需要結(jié)合起來,這篇文章給大家介紹springcloud之Feign超時(shí)提示Read timed out executing POST問題及解決方法,感興趣的朋友一起看看吧

springcloud之Feign超時(shí)提示Read timed out executing POST

問題描述：

Feign接口調(diào)用分兩層，Ribbon的調(diào)用和Hystrix調(diào)用，理論上設(shè)置Ribbon的時(shí)間即可，但是Ribbon的超時(shí)時(shí)間和Hystrix的超時(shí)時(shí)間需要結(jié)合起來，按照木桶原則最低的就是Feign的超時(shí)時(shí)間，建議最好配置超時(shí)時(shí)間一致.當(dāng)Fegin調(diào)用時(shí)，調(diào)用的外部接口，延遲挺大，會(huì)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(shí)時(shí)間
hystrix:
    command:
        default:
            execution:
              timeout:
                enabled: true
              isolation:
                    thread:
                        #超時(shí)設(shè)置
                        timeoutInMilliseconds: 30000
ribbon:
  ReadTimeout: 30000
  #ribbon的超時(shí)時(shí)間
  ConnectTimeout: 30000

補(bǔ)充：

spring cloud 調(diào)用feign請求超時(shí) feign.RetryableException: Read timed out executing POST

問題介紹：

服務(wù)之間調(diào)用報(bào)錯(cuò)超時(shí)，截取部分報(bào)錯(cuò)，Read timed out executing POST http://******

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(bào)錯(cuò)超時(shí)，feign的調(diào)用分兩層，ribbon的調(diào)用和hystrix的調(diào)用，高版本的hystrix默認(rèn)是關(guān)閉的，所以在application.properties配置文件中設(shè)置ribbon即可

#請求處理的超時(shí)時(shí)間
ribbon.ReadTimeout: 120000
#請求連接的超時(shí)時(shí)間
ribbon.ConnectTimeout: 30000

如果開啟hystrix，hystrix的超時(shí)報(bào)錯(cuò)如下圖：

FeignDemo#demo() timed-out and no fallback available。和ribbon超時(shí)報(bào)錯(cuò)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(jī)制
hystrix:
  shareSecurityContext: true
  command:
    default:
      circuitBreaker:
        sleepWindowInMilliseconds: 100000
        forceClosed: true
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 600000
