简介

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

2.3、配置文件application.yml

spring:  application:    name: microservice-consumer-movie-ribbon-with-hystrix1  sleuth:    sampler:      percentage: 1.0  #zipkin:    #base-url: http://localhost:7788server:  port: 8010eureka:  client:    healthcheck:      enabled: true    serviceUrl:      defaultZone: http://jacky:admin@peer1:8761/eureka/,http://jacky:admin@peer2:8762/eureka/,http://jacky:admin@peer3:8763/eureka/  instance:    prefer-ip-address: true    instance-id: ${spring.application.name}:${spring.cloud.client.ipAddress}:${spring.application.instance_id:${server.port}}hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds: 5000#security:  #oauth2:   # resource:    #  id: microservice-consumer-movie-ribbon-with-hystrix1     # user-info-uri: http://localhost:9999/uaa/user      #prefer-token-info: false

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;  }   public String getUsername() {    return this.username;  }   public void setUsername(String username) {    this.username = username;  }   public String getName() {    return this.name;  }   public void setName(String name) {    this.name = name;  }   public Short getAge() {    return this.age;  }   public void setAge(Short age) {    this.age = age;  }   public BigDecimal getBalance() {    return this.balance;  }   public void setBalance(BigDecimal balance) {    this.balance = balance;  } }

2.5、控制层MovieController.java

package com.jacky.cloud.controller; import com.netflix.hystrix.contrib.javanica.annotation.HystrixProperty;import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.PathVariable;import org.springframework.web.bind.annotation.RestController;import org.springframework.web.client.RestTemplate; import com.jacky.cloud.entity.User;import com.netflix.hystrix.contrib.javanica.annotation.HystrixCommand; @RestControllerpublic 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;  }}
