本文基于方志朋先生的博客实现：https://blog.csdn.net/forezp/article/details/70233227

一、准本工作

1、工具：Idea，JDK1.8，Maven3.5

2、创建四个model，名字分别为eurserver（服务注册中心），service-hi（实现断路监控），service-lucy（实现断路监控），service-turbine（断路器聚合监控）

二、创建与实现

1、创建服务注册中心eurserver，右键工程，new ==> model，然后选择Spring Initializr，next。

然后填写model名字，next，选择Cloud Discovery，Eureka Server，next ==>finish

启动一个服务注册中心，主需要一个注解@EnableEurekaServer，这个注解放在springboot的启动工程里。

@SpringBootApplication
@EnableEurekaServer
public class EurserverApplication {

    public static void main(String[] args) {
        SpringApplication.run(EurserverApplication.class, args);
    }
}

填写配置文件：

server:
  port: 8088  //端口号
eureka:
  instance:
    hostname: localhost //主机地址
  client:
    register-with-eureka: false //注册中心告诉自己不能向自己注册自己，默认为true
    fetch-registry: false　　　　
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/

启动项目，访问：localhost:8088

可以看到，没有任何服务向注册中心注册。

2、创建一个service-hi

配置文件：

server.port=8085
# 向服务中心注册

eureka.client.service-url.defaultZone=http://localhost:8088/eureka/   
spring.application.name=service-hi

启动类：

package com.rrg;

// 断路器仪表盘
@EnableHystrixDashboard
@RestController
public class ServiceHiApplication {

    public static void main(String[] args) {
        SpringApplication.run(ServiceHiApplication.class, args);
    }

    // 这个是2.02要添加的，不然仪表盘不显示
    @Bean
    public ServletRegistrationBean getServlet(){
        HystrixMetricsStreamServlet streamServlet = new HystrixMetricsStreamServlet();
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(streamServlet);
        registrationBean.setLoadOnStartup(1);
        registrationBean.addUrlMappings("/hystrix.stream");
        registrationBean.setName("HystrixMetricsStreamServlet");
        registrationBean.setName("HystrixMetricsStreamServlet");
        return registrationBean;
    }

    @Value("${server.port}")
    private String port;
    @RequestMapping("/hi")
    @HystrixCommand(fallbackMethod = "hiErr")
    public String hi(@RequestParam String name){
        return "hi," + name + "I am a port:" + port;
    }

    public String hiErr(@RequestParam String name){
        return "sorry," + name + ",have a error";
    }
}

启动service-hi，访问localhost:8085

然后输入：http://localhost:8085/hystrix.stream，miya，点击Monitor Stream

在访问之前，先访问local host：8085/hi?name=rose，这样那个仪表盘才显示。

到此，已经实现了单个断路器的监控，但是如果要监控多个服务的话，就需要turbine来实现

3、创建一个service-trubine，service-lucy的创建和service-hi一摸一样，就不用多写了。

</project>

配置文件：

server.port=8087
spring.application.name=service-turbine
# 指定聚合哪些集群，多个使用","分割，默认为default。可使用http://.../turbine.stream?cluster={clusterConfig之一}访问
turbine.aggregator.cluster-config=default
#表明监控哪些服务
turbine.app-config=service-hi,service-lucy
turbine.cluster-name-expression=new String("default")
#这里和service-hi启动类里的 registrationBean.addUrlMappings("/hystrix.stream")一致，原因待探索
turbine.instanceUrlSuffix=/hystrix.stream
eureka.client.service-url.defaultZone=http://localhost:8088/eureka/

启动类：

@SpringBootApplication
// @EnableTurbine注解包含了@EnableDiscoveryClient注解
@EnableTurbine
@EnableHystrixDashboard
public class ServiceTurbineApplication {

    public static void main(String[] args) {
        SpringApplication.run(ServiceTurbineApplication.class, args);
    }
}

然后分别启动四个项目：访问localhost:8088

技术分享图片

都已注册。访问local host:8087，输入http://localhost:8087/turbine.stream点击进去。

技术分享图片

可以看到，已经成功的对service-hi和service-lucy聚合监控。
