记录SpringCloud启用 Hystrix 仪表盘功能出现Unable to connect to Command Metric Stream.的异常解决方案

其实仔细查看控制台打印日志：

Origin parameter: http://localhost:1001/actuator/hystrix.stream is not in the allowed list of proxy host names.
If it should be allowed add it to
hystrix.dashboard.proxyStreamAllowList.

可以看出，给出了建议方案
add it to hystrix.dashboard.proxyStreamAllowList

解决方案：
在对应dashboard工程加入如下配置即可

hystrix:
dashboard:
proxy-stream-allow-list: “localhost”
