Spring Cloud - Zuul 无法设置超时

Question

我有一个带有配置文件的 zuul 服务器:

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

我有一些超时时间更长(超过一分钟)的查询。但是，我的所有请求总是因超时而出错，请求时间总是小于 6000 毫秒。

zuul 显示此异常:

有没有人对这种情况有解决方案？

谢谢!

Answer 1

尝试在 ZUUL 配置中为 Ribbon 添加超时。
以下将设置超时 2 分钟。

ribbon:
  ConnectTimeout: 120000
  ReadTimeout: 120000
