注意：这个章节，请结合前几章节一起使用，因为其要调用上一章节的服务

1、pom.xml

      
          
       
        4.0.0
           
               
        
         org.springframework.boot
                
        
         spring-boot-starter-parent
                
        
         2.1.3.RELEASE
                
         
            
           
       
        com.test
           
       
        eureka-client-movie
           
       
        0.0.1-SNAPSHOT
           
       
        eureka-client-movie
           
       
        Demo project for Spring Boot
           
               
        
         1.8
                
        
         Greenwich.SR1
            
           
               
                    
         
          org.springframework.boot
                     
         
          spring-boot-starter-web
                 
                
                    
         
          org.springframework.cloud
                     
         
          spring-cloud-starter-netflix-eureka-server
                 
                
                    
         
          org.springframework.boot
                     
         
          spring-boot-starter-test
                     
         
          test
                 
            
           
               
                    
                         
          
           org.springframework.cloud
                          
          
           spring-cloud-dependencies
                          
          
           ${spring-cloud.version}
                          
          
           pom
                          
          
           import
                      
                 
            
           
               
                    
                         
          
           org.springframework.boot
                          
          
           spring-boot-maven-plugin
                      
                 
            
       
      

2、添加application.yml配置

server:  port: 8664user:  userServicePath: http://localhost:8663/user/spring:  application:    name: eureka-client-movieeureka:  instance:    hostname: localhost    prefer-ip-address: true    instance-id: ${spring.application.name}:${spring.application.instance_id:${server.port}}  client:    serviceUrl:      defaultZone: http://${eureka.instance.hostname}:8661/eureka

3、在启动类添加注解

package com.test.eurekaclientmovie;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.cloud.netflix.eureka.EnableEurekaClient;import org.springframework.context.annotation.Bean;import org.springframework.web.client.RestTemplate;@SpringBootApplication@EnableEurekaClientpublic class EurekaClientMovieApplication {    @Bean    public RestTemplate restTemplate(){        return new RestTemplate();    }    public static void main(String[] args) {        SpringApplication.run(EurekaClientMovieApplication.class, args);    }}

4、MovieController.java

package com.test.eurekaclientmovie.controller;import com.test.eurekaclientmovie.entity.User;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.beans.factory.annotation.Value;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;@RestControllerpublic class MovieController {    @Autowired    private RestTemplate restTemplate;    @Value("${user.userServicePath}")    private String userServicePath;   /* @Autowired    private  LoadBalancerClient loadBalancerClient;*/    @GetMapping("/movie/{id}")    public User findById(@PathVariable Long id) {        //请用虚拟ip        return restTemplate.getForObject(this.userServicePath+id, User.class);    }    /**     * 配置单一的方法进行轮询     * @return     *//*    @GetMapping("/test")    public String test() {        //请用虚拟ip        ServiceInstance serviceInstance =loadBalancerClient.choose("eureka-client-user");        System.out.println(serviceInstance.getHost()+":"+serviceInstance.getPort());        return "1";    }*/}

5、User.java

package com.test.eurekaclientmovie.entity;import java.io.Serializable;import java.math.BigDecimal;public class User implements Serializable {    private  Long id;    private  String name;    private  String username;    private  BigDecimal balance;    private  short age;    public Long getId() {        return id;    }    public void setId(Long id) {        this.id = id;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    public BigDecimal getBalance() {        return balance;    }    public void setBalance(BigDecimal balance) {        this.balance = balance;    }    public short getAge() {        return age;    }    public void setAge(short age) {        this.age = age;    }}

6、实现服务之间的调用，如果访问下面URL有返回值，说明实现了服务之间的调用了，没有实现，请仔细检查配置，也可以留言

http://localhost:8664/movie/1

7、查看eureka-server的情况

http://localhost:8661/

如下图所示
