1. 創建一個Controller類

package com.example.demo;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Administrator on 2018-06-09.
 */
@RestController
public class DemoController {

    @RequestMapping("hello")
    
 
public String hello(){
        return "hello world!";
    }

}

2. 啟動應用，右鍵選中DemoApplication.java,在彈出菜單中選擇run或debug

3. 輸入訪問地址 http://localhost:8080/hello
