Question

我试图在application.yml中设置属性以设置功能区和hystrix的超时，但我无法做到这一点。我总是遇到同样的问题： “未知属性hystrix.command” 和 “未知属性功能区。ConnectTimeout”

hystrix:
  command:
    default:
      execution:
        isolation:
          thread:
            timeoutInMilliseconds: 11000
ribbon:
  ConnectTimeout: 10000
  ReadTimeout: 10000

使用 Finchley.SR1 BTW。

总是出现相同的错误：

Answer 1

去芬奇利后，我遇到了同样的错误。调整ribbon.ConnectTimeout和ribbon.ReadTimeout之后，错误消失了。

ribbon:
  ConnectTimeout: 2000
  ReadTimeout: 2000

尝试运行负载测试（例如在jMeter中），查看负载下服务器的最大响应时间是多少，也许读取时间为10000毫秒，连接时间为10000毫秒是不够的。

PS

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds必须大于ribbon.ConnectTimeout + Ribbon.ReadTimeout。

Answer 2

尽管它说未知属性，但是在zuul网关中添加属性可以很好地调整超时。以下是我可以使其正常运行的配置。

hystrix.command.default.execution.timeout.enabled= true

ribbon.ReadTimeout=5000
ribbon.ConnectTimeout=5000

#(ribbon.ReadTimeout + ribbon.connectTimeout) * (1+ribbon.maxAutoRetries(default 0) * (ribbon.MaxAutoRetriesNextServer (default 1) + 1)

#timeoutInMilliseconds= (5000 + 5000) * (1+0)*(1+1) =20000

hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=21000

无法设置功能区和hyxtrix的超时时间
