idea创建Eureka consumer入门实例

第一步创建工程

1、选择File，然后new 再然后Project,选择Spring Initializr然后下一步

2、填写项目信息，然后下一步

3、选择依赖 Spring Cloud Discovery 然后选择Eureka Discovery Client ,然后下一步

4、创建项目存储位置及名称

第二步，创建BeanConfiguration的类，创建RestTemplate

 1 package com.ssc.consumer;
 2 
 3 import org.springframework.cloud.client.loadbalancer.LoadBalanced;
 4 import org.springframework.context.annotation.Bean;
 5 import org.springframework.context.annotation.Configuration;
 6 import org.springframework.web.bind.annotation.GetMapping;
 7 import org.springframework.web.client.RestOperations;
 8 import org.springframework.web.client.RestTemplate;
 9 
10 @Configuration
11 public class BeanConfiguration {
12    @Bean
13    @LoadBalanced
14     public RestTemplate getRestTemplate(){
15         return new RestTemplate();
16     }
17 
18 
19 }

第三步写调用接口

 1 package com.ssc.consumer;
 2 
 3 import org.springframework.beans.factory.annotation.Autowired;
 4 import org.springframework.web.bind.annotation.GetMapping;
 5 import org.springframework.web.bind.annotation.RestController;
 6 import org.springframework.web.client.RestTemplate;
 7 
 8 @RestController
 9 public class ConsumerController {
10     @Autowired
11     private RestTemplate restTemplate;
     //直接调用
12     @GetMapping("/consumer/callHello")
13     public String callHello(){
14         return restTemplate.getForObject("http://localhost:8055/user/hello",String.class);
15     }
16 //通过Eureka调用
17     @GetMapping("/consumer/callHello2")
18     public String callHello2(){
19         return restTemplate.getForObject("http://eureka-user-provide/user/hello",String.class);
20     }
21 
22 }

第四步、添加application.yml文件

1 spring:
2   application:
3     name: eureka-user-consumer
4 server:
5   port: 8056
6 eureka:
7   client:
8     service-url:
9       defaultZone: http://localhost:8761/eureka

第五步、启动程序，访问 http://localhost:8056/consumer/callHello2查看效果
