Hystrix Dashboard中proxyStreamAllowList导致的【Unable to connect to Command Metric Stream.】问题

看看log:

ashboardConfiguration$ProxyStreamServlet : Origin parameter: http://localhost:9000/actuator/hystrix.stream is not in the allowed list of proxy host names.  If it should be allowed add it to hystrix.dashboard.proxyStreamAllowList.

接下来就很简单了，HystrixDashboard工程加入配置。

hystrix:
  dashboard:
    proxy-stream-allow-list: "localhost"

然后就可以了！
