Ribbon可以整合整合断路器监控Hystrix Dashboard，Feign也不能少, 本篇讲解一下Feign如何整合断路器监控Hystrix Dashboard。本篇主要整合sc-eureka-client-consumer-feign-hystrix项目和sc-hystrix-dashboard项目。
1、 新建项目sc-feign-hystrix-dashboard，对应的pom.xml文件如下
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>spring-cloud</groupId>
<artifactId>sc-feign-hystrix-dashboard</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>sc-feign-hystrix-dashboard</name>
<url>http://maven.apache.org</url>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.4.RELEASE</version>
</parent>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Finchley.RELEASE</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencyManagement>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
<dependencies>
<!-- 说明是一个 eureka client -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<!-- <dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-feign</artifactId>
<version>1.4.5.RELEASE</version>
</dependency> -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
<!-- <dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-hystrix-dashboard</artifactId>
<version>1.4.5.RELEASE</version>
</dependency> -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-hystrix-dashboard</artifactId>
</dependency>
<!-- <dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-hystrix</artifactId>
<version>1.4.5.RELEASE</version>
</dependency> -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
</dependencies>
</project>
说明：可以看出这个pom.xml文件是sc-eureka-client-consumer-feign-hystrix项目和sc-hystrix-dashboard项目的并集。
2、 新建spring root 启动类FeignDashboardApplication.java
package sc.consumer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;
import org.springframework.cloud.openfeign.EnableFeignClients;
@SpringBootApplication
@EnableEurekaClient
@EnableFeignClients
@EnableHystrixDashboard
public class FeignDashboardApplication {
public static void main(String[] args) {
SpringApplication.run(FeignDashboardApplication.class, args);
}
}
这个启动类的注解是sc-eureka-client-consumer-feign-hystrix项目和sc-hystrix-dashboard项目的并集
3、 其他项目文件说明如下，具体见源码
4、 启动注册中心sc-eureka-server和服务提供者sc-eureka-client-provider，并确保启动成功
5、 启动sc-feign-hystrix-dashboard项目，并验证是否启动成功
方式一：访问注册中心查看sc-feign-hystrix-dashboard项目配置的服务名是否注册成功
方式二：访问仪表盘Dashboard对的地址http://127.0.0.1:5800/hystrix
6、 使用Hystrix Dashboard查看服务情况
在下图标注处输入http://127.0.0.1:5800/hystrix.stream
然后点击Monitor Stream按钮
7、 使用postman访问任意服务接口，以访问获取用户信息接口为例
http://127.0.0.1:5800/feign/user/getUser/3
尽量多访问几次，然后查看仪表盘Bashboard监控后台，发现之前一直处于Loading的界面发生了变化，如下图，图中单元具体含义可以访问网站
https://github.com/Netflix-Skunkworks/hystrix-dashboard/wiki
访问http://127.0.0.1:5800/hystrix.stream也出现大量数据，这些数据就是对服务的监控数据。
