feign.RetryableException: Read timed out executing POST xxx

问题介绍:

服务之间调用报错超时,截取部分报错,Read timed out executing POST http://******

原因及解决办法:

明显可以看到是http请求报错超时,feign的调用分两层,ribbon的调用和hystrix的调用,高版本的hystrix默认是关闭的,所以在application.properties配置文件中设置ribbon即可

  1. ribbon:
  2.   ReadTimeout: 60000
  3.   ConnectTimeout: 60000
  4.   eureka:
  5.     enable: true

 

如果开启hystrix,hystrix的超时报错如下图:

FeignDemo#demo() timed-out and no fallback available。和ribbon超时报错还是有区别的

  1. com.netflix.hystrix.exception.HystrixRuntimeException: FeignDemo#demo() timed-out and no fallback available.
  2.     at com.netflix.hystrix.AbstractCommand$22.call(AbstractCommand.java:819)
  3.     at com.netflix.hystrix.AbstractCommand$22.call(AbstractCommand.java:804)
  4.     at rx.internal.operators.OperatorOnErrorResumeNextViaFunction$4.onError(OperatorOnErrorResumeNextViaFunction.java:140)
  5.     at rx.internal.operators.OnSubscribeDoOnEach$DoOnEachSubscriber.onError(OnSubscribeDoOnEach.java:87)
  6.     at rx.internal.operators.OnSubscribeDoOnEach$DoOnEachSubscriber.onError(OnSubscribeDoOnEach.java:87)
  7.     at com.netflix.hystrix.AbstractCommand$DeprecatedOnFallbackHookApplication$1.onError(AbstractCommand.java:1472)
  8.     at com.netflix.hystrix.AbstractCommand$FallbackHookApplication$1.onError(AbstractCommand.java:1397)
  9.     at rx.internal.operators.OnSubscribeDoOnEach$DoOnEachSubscriber.onError(OnSubscribeDoOnEach.java:87)
  10.     at rx.observers.Subscribers$5.onError(Subscribers.java:230)
  11.     Caused by: java.util.concurrent.TimeoutException
  12.     at com.netflix.hystrix.AbstractCommand.handleTimeoutViaFallback(AbstractCommand.java:997)
  13.     at com.netflix.hystrix.AbstractCommand.access$500(AbstractCommand.java:60)

  15.     at com.netflix.hystrix.AbstractCommand$12.call(AbstractCommand.java:601)

 

解决办法:

  1. feign.hystrix.enabled: true
  2. hystrix 熔断机制
  3. hystrix:
  4.   shareSecurityContext: true
  5.   command:
  6.     default:
  7.       circuitBreaker:
  8.         sleepWindowInMilliseconds: 100000
  9.         forceClosed: true
  10.       execution:
  11.         isolation:
  12.           thread:
  13.             timeoutInMilliseconds: 600000
