第一步 创建一个监控页面的module

第二部 导入所需要的依赖

  <dependencies>
        <!--hystrix依赖-->
        <!--导入hystrix依赖-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-hystrix</artifactId>
            <version>1.4.6.RELEASE</version>
        </dependency>
        <!--hystrix监控页面依赖-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
            <version>1.4.6.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>com.rpf</groupId>
            <artifactId>springcloud-api</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--热部署-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
        </dependency>
        <!--集成Ribbon-->
        <!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-ribbon -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-ribbon</artifactId>
            <version>1.4.6.RELEASE</version>
        </dependency>
        <!--需要Eureka发现服务-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
            <version>1.4.6.RELEASE</version>
        </dependency>
    </dependencies>

第三步 配置yml文件

server:
  port: 9000

启动类上开启监控页面注解

@SpringBootApplication
@EnableHystrixDashboard//开启监控页面
public class DeptConsumerDashboard_9000 {
    public static void main(String[] args) {
        SpringApplication.run(DeptConsumerDashboard_9000.class,args);
    }
}

第四步 确保服务提供方pom依赖加入了监控信息的依赖

  <!--添加监控信息-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

开启启动类访问地址http://localhost:9000/hystrix 即可得到以下界面

这个时候我们需要在服务提供方注册一些监控信息服务提供方需要导入hystrix的依赖

 <!--hystrix-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-hystrix</artifactId>
            <version>1.4.6.RELEASE</version>
        </dependency>

在服务提供者的启动类中注入一个bean

//启动类
@EnableEurekaClient//在服务启动后自动注册到Eureka服务端
@SpringBootApplication
@EnableDiscoveryClient//服务发现
public class DeptProvider_8001 {
    public static void main(String[] args) {
        SpringApplication.run(DeptProvider_8001.class,args);
    }

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

启动注册中心，服务提供方，监控moudle 访问下方路径看是否有数据
