spring-cloud-zuul timeout configuration does not work

问题

according to spring cloud zuul 8.1.3 zuul timeout, the following configuration should make zuul timeout after 20 seconds, however, it times out at 10 seconds.

server:
  port: 8769
spring:
  application:
    name: service-zuul
zuul:
  host:
    connect-timeout-millis: 20000
    socket-timeout-millis: 60000
zuul:
  routes:
    tp:
      path: /**
      url: http://localhost:9998
ribbon:eureka:enabled: false

From console output one can see that the interval between filter and timeout exception is only 10 seconds. which means the zuul.host.connect-timeout-millis does not work.

I finally found a solution:

I used properties before and this is the first time to try yml, it seems that an item must be aggregated into one prefix:

zuul:
  host:
    connect-timeout-millis: 20000
    socket-timeout-millis: 60000
  routes:
    tp:
      path: /**
      url: http://localhost:9998

In this way the backend server could have at most 60 seconds to respond. Besides, I also found that the sequence in configuration matters.

Try to define the below properties instead if you are using Zuul withe Eureka.

ribbon:
  ReadTimeout: 60000
  ConnectTimeout: 20000

If you are using Zuul with Eureka, Zuul will use RibbonRoutingFilter for routing instead of SimpleHostRoutingFilter. In this case, HTTP requests are handled by Ribbon.
