docker-hystrix-dashboard-turbine：

Hystrix的主要优点之一是它收集关于每个HystrixCommand的一套指标。

了解springcloud架构可以加求求：三五三六二四七二五九
Hystrix仪表板以有效的方式显示每个断路器的运行状况，通过Hystrix Dashboard我们可以在直观地看到各Hystrix Command的断路器是否打开，请求响应时间, 请求失败率，请求超时个数等等数据。

但是只使用Hystrix Dashboard的话, 你只能看到单个应用内的服务信息, 这明显不够. 我们需要一个工具能让我们汇总系统内多个服务的数据并显示到Hystrix Dashboard上, 这个工具就是Turbine，
，这节我们讨论一下，怎么用turbine+hystrix-dashboard监听两个消费者服务

一、监听模块microservice-consumer-movie-feign-with-hystrix断路器的运行状况

二、监听模块microservice-consumer-movie-ribbon-with-hystrix1断路器的运行状况

2.1、创建模块microservice-consumer-movie-ribbon-with-hystrix1

项目结构如下：

2.2、pom.xml文件

                        build-image
                        install
                        
                            build
                        
                    
                
                
                    
                    http://192.168.6.130:5678
                    true
                    
                    ${docker.repostory}/${docker.image.prefix}/${project.artifactId}:${project.version}
                    
                    java:openjdk-8-jdk-alpine
                    
                    ["java", "-jar", "/${project.build.finalName}.jar"]
                    
                        
                            /
                            ${project.build.directory}
                            ${project.build.finalName}.jar

2.3、配置文件application.yml

2.4、实体类User.java

package com.jacky.cloud.entity;

import java.math.BigDecimal;

public class User {
  private Long id;

  private String username;

  private String name;

  private Short age;

  private BigDecimal balance;

  public Long getId() {
    return this.id;
  }

  public void setId(Long id) {
    this.id = id;

import com.jacky.cloud.entity.User;
import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand;

@RestController
public class MovieController {
  @Autowired
  private RestTemplate restTemplate;

  @GetMapping("/movie/{id}")
  @HystrixCommand(groupKey="UserGroup1", commandKey = "findUserByIdCommand1",commandProperties = {
          @HystrixProperty(name = "execution.isolation.thread.timeoutInMilliseconds", value = "1000"),
          @HystrixProperty(name = "execution.timeout.enabled", value = "false")},fallbackMethod = "findByIdFallback")
  public User findById(@PathVariable Long id) {
    return this.restTemplate.getForObject("http://microservice-provider-user/simple/" + id, User.class);
  }

  /**
   * fallback方法
   * @param id
   * @return
     */
  public User findByIdFallback(Long id) {
    User user = new User();
    user.setId(5L);
    return user;
  }
}
