Java springcloud B2B2C o2o多用戶商城 springcloud架構-docker-hystrix-dashboard-turbine（九）

簡介

Hystrix的主要優勢之一是它收集關於每一個HystrixCommand的一套指標。Hystrix儀表板以有效的方式顯示每一個斷路器的運行情況，經過Hystrix Dashboard咱們能夠在直觀地看到各Hystrix Command的斷路器是否打開，請求響應時間, 請求失敗率，請求超時個數等等數據。可是隻使用Hystrix Dashboard的話, 你只能看到單個應用內的服務信息, 這明顯不夠. 咱們須要一個工具能讓咱們彙總系統內多個服務的數據並顯示到Hystrix Dashboard上, 這個工具就是Turbine，這節咱們討論一下，怎麼用turbine+hystrix-dashboard監聽兩個消費者服務

1、監聽模塊microservice-consumer-movie-feign-with-hystrix斷路器的運行情況

2、監聽模塊microservice-consumer-movie-ribbon-with-hystrix1斷路器的運行情況

2.一、建立模塊microservice-consumer-movie-ribbon-with-hystrix1

2.三、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:7788
server:
  port: 8010
eureka:
  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

2.四、實體類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;
  }
 
}

2.五、控制層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;
 
@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;
  }
}
