Hystrix Dashboard出現Unable to connect to Command Metric Stream

情況描述

feign項目添加hystrix dashboard監控面闆，添加了一下依賴：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
</dependency>
           

運作項目出現Unable to connect to Command Metric Stream錯誤

原因

springboot 版本如果是2.0以上的dashboard的通路預設路徑不是 “/hystrix.stream”，這就需要自己添加通路配置，修改通路路徑，

隻要在自己的項目裡配置上下面的servlet就可以了

在啟動類添加如下方法

添加通路路徑

@Bean
    public ServletRegistrationBean getServlet(){
        HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);
        registrationBean.setLoadOnStartup(1);
        registrationBean.addUrlMappings("/actuator/hystrix.stream");
        registrationBean.setName("HystrixMetricsStreamServlet");
        return registrationBean;
    }
