Spring Boot 使用IntelliJ IDEA创建一个web开发实例(二)

1. 创建一个Controller类 

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. 启动应用，右键选中DemoApplication.java,在弹出菜单中选择run或debug

3. 输入访问地址 http://localhost:8080/hello
