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

package com.ssc.consumer;

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

@Configuration
public class BeanConfiguration {
   @Bean
   @LoadBalanced
    public RestTemplate getRestTemplate(){
        return new RestTemplate();
    }


}

第三步写调用接口

package com.ssc.consumer;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

@RestController
public class ConsumerController {
    @Autowired
    private RestTemplate restTemplate;
     //直接调用
    @GetMapping("/consumer/callHello")
    public String callHello(){
        return restTemplate.getForObject("http://localhost:8055/user/hello",String.class);
    }
//通过Eureka调用
    @GetMapping("/consumer/callHello2")
    public String callHello2(){
        return restTemplate.getForObject("http://eureka-user-provide/user/hello",String.class);
    }

}

第四步、添加application.yml文件

spring:
  application:
    name: eureka-user-consumer
server:
  port: 8056
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka

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