com.netflix.zuul.exception.ZuulException: Hystrix Readed time out

问题

I am trying microservices with eureka and zuul. And there is a problem with all requests, which take more then 1 second. As I have understood, 1 second is default hystrix timeout, and for configuring timeouts in Zuul, I have to configure these properties:

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds ribbon.ConnectTimeout
ribbon.ReadTimeout

but when I set them, there is "Cannot resolve configuration property ..." warning on each of them in the Intelije Idea. And, it seems, they are not applied and don't work.

This way you will increase Hystrix timeout (globaly):

hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 5000

or per service:

hystrix:
  command:
    <serviceName>:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 5000

Add the following property in Zuul gateway service

hystrix:
   command:
      default:
         execution:
            iso lation:
               thread:
                  timeoutInMilliseconds: 30000

ribbon:
   ReadTimeout: 60000
   connection-timeout: 3000
   eureka:
      enabled: true

zuul:
   ignoredServices: '*'
   host:
      time-to-live: -1
      connect-timeout-millis: 5000
      max-per-route-connections: 10000
      max-total-connections: 5000
      socket-timeout-millis: 60000
   semaphore:
      max-semaphores: 500

Setting robbin readTime in zuul server should solve this problem.

ribbon:
  ReadTimeout: 60000

Note: ReadTimeout is case sentience. Hope it helps.
