1. 整合监控页面

1. 新建一个模块 ：springcloud-03-consumer-dept-hystrix-dashboard

2. 导入依赖

   		<!--ribbon-->

   		</plugins>
   	</build>
   
   </project>
   

3. 编写 yml

   server:
     port: 9010
   

4. 在主启动类上添加启动监控的注解

   //开启监控页面
   @EnableHystrixDashboard
   

5. 确保服务端有以下依赖

   <!--actuator 完善监控信息-->
   	<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-starter-actuator -->
   	<dependency>
   		<groupId>org.springframework.boot</groupId>
   		<artifactId>spring-boot-starter-actuator</artifactId>
   	</dependency>
   <!-- hystrix -->
   	<!-- https://mvnrepository.com/artifact/org.springframework.cloud/spring-cloud-starter-hystrix -->
   	<dependency>
   		<groupId>org.springframework.cloud</groupId>
   		<artifactId>spring-cloud-starter-hystrix</artifactId>
   		<version>1.4.7.RELEASE</version>
   	</dependency>
   

6. 启动该项目

   访问 ： http://localhost:9010/hystrix

   

2. 配置监控

1. 修改服务端的主启动类

   添加开启熔断开关的注解

   增加一个 Dashboard 的 Bean，并注册

   @SpringBootApplication
   //在配置过这个注解后，服务启动会自动注册到 Eureka Server
   @EnableEurekaClient
   //开启服务发现
   @EnableDiscoveryClient
   //开启熔断开关
   @EnableCircuitBreaker
   public class Springcloud02ProviderDept8081Application {
   
   	public static void main(String[] args) {
   		SpringApplication.run(Springcloud02ProviderDept8081Application.class, args);
   	}
   
   	/**
   	 * 增加一个 Dashboard 的 Bean
   	 * 固定的代码
   	 */
   	@Bean
   	public ServletRegistrationBean HystrixMetricsStreamServlet(){
   		ServletRegistrationBean registrationBean = new ServletRegistrationBean(new HystrixMetricsStreamServlet());
   		//添加路径
   		registrationBean.addUrlMappings("/actuator/hystrix.stream");
   		return registrationBean;
   	}
   }
   
   

2. 修改服务端的控制层

   在所有需要监控的接口上面加上注解

   @HystrixCommand
   

3. 启动集群

   访问 ： http://localhost:9010/hystrix

4. Hystrix Dashboard 页面填入信息

   

5. 进入监控页面

   
   注： 如果一直显示 Loading ，发送一个查询请求再看一下

3. 监控中心各项信息介绍

最后
