一、编写三个module

1. springcloud-consumer-hystrix-dashboard

1.导入依赖

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-hystrix</artifactId>
            <version>1.4.6.RELEASE</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-hystrix-dashboard -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
            <version>1.4.6.RELEASE</version>
        </dependency>

 2.端口配置

 4.结构目录

5.开启监控

 

 2.springcloud-eureka-7001

作为服务springcloud-provider-dept-hystrix-8001的注册中心

3.springcloud-provider-dept-hystrix-8001

1.导入服务的监控依赖和hystrix

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-hystrix</artifactId>
            <version>1.4.6.RELEASE</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-eureka -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

2.在主启动类上增加一个servlet

//增加一个servlet
    @Bean
    public ServletRegistrationBean hystrixMetricsStreamServlet(){
        ServletRegistrationBean registrationBean = new ServletRegistrationBean(new HystrixMetricsStreamServlet());
        registrationBean.addUrlMappings("/actuator/hystrix.stream");
        return registrationBean;
    }

3.开启支持

 

二、开启注册中心和服务以及Dashboard监控

1.eureka注册中心

 2.服务成功访问

 

3. 监控页面

4.输入添加Bean里的地址

 5.访问成功
