springCloud-4.RestTemplat的使用(两个client之间的调用)

1.启动eurka-serverjava

2.在client端口8080编写一个hello world方法,而且能访问web

 

3.建立client-test1项目spring

4.调用EUREKA-CLIENT的index方法,新建RestTemplat启动配置app

5.新建调用index类测试

package com.client.test.clienttest1;

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

/**
 * 描述:
 *
 * @outhor hekang
 * @create 2018-07-30 下午3:31
 */
@RestController
public class ClientController {
    @Autowired
    private RestTemplate restTemplate;

    @RequestMapping("getIndex")
    public String getIndex(){
        String res = restTemplate.getForObject("http://EUREKA-CLIENT/index", String.class);
        return  res;
    }

}

 

6.启动,访问http://localhost:8081/getIndex,测试3d

注册成功:rest

 

访问http://localhost:8081/getIndex   成功打印code
