consumer端不引用spring-boot-starter-actuator的情況

Consumer端會報Unable to connect to Command Metric Stream。新建HystrixConfiguration類加入以下代碼：

import com.netflix.hystrix.contrib.metrics.eventstream.HystrixMetricsStreamServlet;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
 
import org.springframework.context.annotation.Configuration;

@Configuration
public class HystrixConfiguration {
    @Bean
    public ServletRegistrationBean<HystrixMetricsStreamServlet> getServlet(){
        HystrixMetricsStreamServlet hystrixMetricsStreamServlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean
 
<HystrixMetricsStreamServlet> servletRegistrationBean = new ServletRegistrationBean();
        servletRegistrationBean.setServlet(hystrixMetricsStreamServlet);
        servletRegistrationBean.addUrlMappings("/hystrix.stream");
        servletRegistrationBean.setName("HystrixMetricsStreamServlet");
        
 
return servletRegistrationBean;
    }
}

consumer端開放端點，配置文件中加入：

management.endpoints.web.exposure.include=hystrix.stream,health,info

默認值為health,info

hystrix-dashboord輸入的地址為http://consumerhost:port/hystrix.stream

turbine站點配置文件加入：

turbine.appConfig=xxx1,xxx2,x3
turbine.instanceUrlSuffix=/hystrix.stream

xxx1為consumer端配置的應用程序名(如spring.application.name=xxx1)，通過eareka-server自動找到對應的consumer接口http://consumerhost:port/hystrix.stream去抓取信息顯示到turbine聚合界面上。

由於spring-boot-starter-actuator的默認context-path為actuator，若turbine.instanceUrlSuffix不做設置，默認路徑為/actuator/hystrix.stream，與我們在consumer中設置的路徑/hystrix.stream不匹配，所以出現/actuator/hystrix.stream 404 Not Found。

聚合hystrix-dashboord輸入的地址為http://consumerhost:port/turbine.stream

consumer端引用spring-boot-starter-actuator的情況（推薦）

consumer端開放端點，配置文件中加入：

management.endpoints.web.exposure.include=hystrix.stream,health,info

默認值為health,info

hystrix-dashboord輸入的地址為http://consumerhost:port/actuator/hystrix.stream

turbine站點配置文件加入：

turbine.appConfig=xxx1,xxx2,xxx3
turbine.instanceUrlSuffix=/actuator/hystrix.stream

/actuator/hystrix.stream為默認地址也可以不寫。

聚合hystrix-dashboord輸入的地址為http://consumerhost:port/turbine.stream

spring cloud(Greenwich.M2) hystrix dashboard 報/actuator/hystrix.stream 404 Not Found的問題
