Spring Hystrix在第一次zuul呼叫时读取超时状态504

第一次打电话给zuul时，我总是收到“Hystrix Readed Timeout”错误消息。我使用的是“Greenwich.RELEASE”SpringCloud版本

我试图在zuul的bootstrap.yml中包含hystrix.command.default.execution.isolation.thread.timeoutinmillizes:5000属性，但它给了我错误未知属性“hystrix.command”。

下面是错误日志

根据，您需要使用一些属性

我试过这个，对我有效：

zuul.host.socket-timeout-millis=20000
zuul.host.connect-timeout-millis=20000
ribbon.ConnectTimeout=10000
ribbon.ReadTimeout=10000

---

我最近遇到了同样的问题。只需覆盖以下超时值

hystrix.command.default.execution.isolation.thread.timeoutinmillizes=150000 ribbon.ReadTimeout=150000 ribbon.ConnectTimeout=150000
