> **我们可以发现：默认生成的Spring Boot项目，主程序已经生成好了，我们只需要编写自己的逻辑。**

## resources文件夹中目录结构 ##

<table> 
 <thead> 
  <tr> 
   <th>文件夹</th> 
   <th>说明</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td><strong>static</strong></td> 
   <td><strong>保存所有的静态资源如 js css images</strong></td> 
  </tr> 
  <tr> 
   <td><strong>templates</strong></td> 
   <td><strong>保存所有的模板页面；（Spring Boot默认jar包使用嵌入式的Tomcat，默认不支持JSP页 面）可以使用模板引擎（freemarker、thymeleaf）</strong></td> 
  </tr> 
  <tr> 
   <td><strong>application.properties</strong></td> 
   <td><strong>Spring Boot应用的配置文件，可以修改一些默认设置</strong></td> 
  </tr> 
 </tbody> 
</table>

# 运行测试 #

## 编写controller ##

**HelloController：**

package com.keafmd.springboot.controller;
    
    import org.springframework.stereotype.Controller;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.bind.annotation.ResponseBody;
    import org.springframework.web.bind.annotation.RestController;
    
    /** * Keafmd * * @ClassName: HelloController * @Description: * @author: 牛哄哄的柯南 * @date: 2021-02-22 20:36 */
    
    /*@ResponseBody //这个类的所有的方法返回的数据直接写给浏览器（如果是对象还能转为json对象） @Controller*/
    @RestController  //等价于上面两个
    public class HelloController { 
    
    
        @RequestMapping("/hello")
        public String hello(){ 
            return "Hello World!--quick";
        }
    }

## 项目目录结构 ##

## 启动主程序 ##
