1.新建Module，springcloud-consumer-hystrix-dashboard。

2.复制80里面的依赖，并加入hystrix的依赖和dashboard的依赖。

<!-- hystrix -->
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
    <version>2.1.1.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-netflix-hystrix-dashboard</artifactId>
    <version>2.1.1.RELEASE</version>
</dependency>

3.新建application.yml文件，配置端口9001

4.新建启动类

package com.allen.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;

@SpringBootApplication
@EnableHystrixDashboard
public class DeptConsumerDashboard_9001 {
    public static void main(String[] args) {
        SpringApplication.run(DeptConsumerDashboard_9001.class, args);
    }
}

5.启动测试

6.在springcloud-provider-dept-hystrix-8001启动类里面新增一个Servlet，前提要满足maven依赖里面有这两个依赖。

@Bean
public ServletRegistrationBean hystrixMetricsStreamServlet(){
    ServletRegistrationBean registrationBean = new ServletRegistrationBean(new HystrixMetricsStreamServlet());
    registrationBean.addUrlMappings("/actuator/hystrix.stream");
    return registrationBean;
}

7.启动测试，7001注册中心，8001服务提供者，80服务消费者，9001监控。
