application.properties

eureka.client.service-url.defaultZone=http://localhost:8001/eureka/server.port=8010spring.application.name=hystrix-dashboard-service-hi# 下面的必须配置 不然访问https://hystrix-app:port/actuator/hystrix.stream 会报404management.endpoints.web.exposure.include=*management.endpoints.web.cors.allowed-origins=*management.endpoints.web.cors.allowed-methods=*

HystrixDashboardServiceHiApplication.java

package com.xiaobu;import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand;import lombok.extern.slf4j.Slf4j;import org.springframework.beans.factory.annotation.Value;import org.springframework.boot.CommandLineRunner;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.client.circuitbreaker.EnableCircuitBreaker;import org.springframework.cloud.client.discovery.EnableDiscoveryClient;import org.springframework.cloud.netflix.eureka.EnableEurekaClient;import org.springframework.cloud.netflix.hystrix.EnableHystrix;import org.springframework.cloud.netflix.hystrix.dashboard.EnableHystrixDashboard;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.RestController;/** * @author xiaobu */@SpringBootApplication@EnableEurekaClient@EnableDiscoveryClient@RestController@EnableHystrix@EnableHystrixDashboard@EnableCircuitBreaker@Slf4jpublic class HystrixDashboardServiceHiApplication implements CommandLineRunner {
       public static void main(String[] args) {
           SpringApplication.run( HystrixDashboardServiceHiApplication.class, args );    }    @Value("${server.port}")    String port;    @RequestMapping("/hi")    @HystrixCommand(fallbackMethod = "hiError")    public String home(@RequestParam(value = "name", defaultValue = "admin") String name) {
           return "hi " + name + " ,i am from port:" + port;    }    public String hiError(String name) {
           return "hi,"+name+",sorry,error!";    }    @Override    public void run(String... args) throws Exception {
           log.info("服务hystrix-dashboard-service-hi在端口:{},启动成功....",port);    }}

运行程序： 依次开启eureka-server(与第一章相同)和hystrix-dashboard-service-hi.

访问 http://localhost:8010/hi

然后访问 http://localhost:8010/actuator/hystrix.stream

访问 http://localhost:8010/hystrix

依次输入

http://localhost:8010/actuator/hystrix.stream 2000 admin

再次访问 http://localhost:8010/hystrix 出现如下示图
