修改pom

<!-- Ribbon相关 -->

   <dependency>

     <groupId>org.springframework.cloud</groupId>

     <artifactId>spring-cloud-starter-eureka</artifactId>

   </dependency>

   <dependency>

     <groupId>org.springframework.cloud</groupId>

     <artifactId>spring-cloud-starter-ribbon</artifactId>

   </dependency>

   <dependency>

     <groupId>org.springframework.cloud</groupId>

     <artifactId>spring-cloud-starter-config</artifactId>

   </dependency>

修改application.yml

追加eureka的服务注册地址

server:
  port: 80
#指定端口,具体视自己情况而定,只要不重复就可以
#spring:
#  devtools:
#    livereload:
#      port: 35730

eureka:
  client:
    register-with-eureka: false
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka/,http://eureka7002.com:7002/eureka/,http://eureka7003.com:7003/eureka/

对ConfigBean进行新注解@LoadBalanced

获得Rest时加入Ribbon的配置

package com.matthew.springcloud.cfgbeans;

import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;

/**
 * @Description TODO
 * @Author Matthew
 * @Date 2019/6/29 20:27
 * @Version 1.0
 */
@Configuration
public class ConfigBean { //boot -->spring applicationContext.xml --->@Configuration ConfigBean = applicationContext.xml

    @Bean
    @LoadBalanced//Spring Cloud Ribbon是基于Netflix Ribbon实现的一套客户端   负载均衡工具
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }

}
/*@Bean
    public UserService getUserService(){
        return new UserServiceImpl();
    }*/
//<bean id="userService" class="com.matthew.tmall.UserServiceImpl">

主启动类DeptConsumer80——App添加@EnableEurekaClient

package com.matthew.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

/**
 * @Description TODO
 * @Author Matthew
 * @Date 2019/6/29 20:53
 * @Version 1.0
 */
@EnableEurekaClient
@SpringBootApplication
public class DeptConsumer80_App {
    public static void main(String[] args) {
        SpringApplication.run(DeptConsumer80_App.class, args);
    }

}

修改DeptController_Consumer客户端访问类

//private static final String REST_URL_PREFIX = "http://localhost:8001";

  private static final String REST_URL_PREFIX = "http://MICROSERVICECLOUD-DEPT";
