Spring cloud - Zuul cannot set timeout

Question

I have a zuul server with a config file as:

server:
  port: 9090
eureka:
  client:
    serviceUrl:
      defaultZone: http://172.16.5.147:8761/eureka/
  instance:
    leaseRenewalIntervalInSeconds: 30
    hostname: dev-zuulserver
    non-secure-port: 80
zuul:
          prefix: /v1
          sensitiveHeaders: Cookie, Set-Cookie
          ignoredHeaders: Access-Control-Allow-Origin
          host:
            connect-timeout-millis: 60000 # starting the connection
            socket-timeout-millis: 120000  # monitor the continuous incoming data flow
        ribbon:
          eureka:
            enabled: true
            ReadTimeout: 120000
            ConnectTimeout: 3000
        hystrix:
          command:
            default:
              execution:
                isolation:
                  strategy: THREAD
                  thread:
                    timeoutInMilliseconds: 60000

And I have some queries with longer timeout (more than one minute). But, all my requests always error out with a time out, request time always is less than 6000 ms.

And zuul show this exception:

Caused by: java.lang.RuntimeException: java.net.SocketTimeoutException: Read timed out

Does anyone have a solution for this case?

Thank you!

Answer 1

Try by adding timeout for Ribbon in ZUUL config.
Following will set timeout of 2min.

ribbon:
  ConnectTimeout: 120000
  ReadTimeout: 120000

Answer 2

In your application.properties just add:

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 240000
ribbon.ConnectTimeout: 120000
ribbon.ReadTimeout: 120000
