我可以看到 hystrix 仪表板：http://localhost:8081/hystrix
我还看到我的电路中断和回退方法也可以正常工作但是我无法在http://localhost:8081/actuator/hystrix看到我的应用程序数据.stream
当我查看 /actuator/conditions 时，我看到 Hystrix 出现以下错误
"HystrixAutoConfiguration.HystrixServletAutoConfiguration": {
"notMatched": [
{
"condition": "OnClassCondition",
"message": "@ConditionalOnClass did not find required class 'com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet'"
}
],
"matched": []
}
