最简单SpringBoot

    本次最简单的SpringBoot项目主要有Application，Controller，properties，pom.xml组成，旨在用最简单的代码搭建一个简单易懂的SpringBoot项目，可以快速入门学习。

package com.example.demo;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplicationpublic class DemoApplication {    public static void main(String[] args) {        SpringApplication.run(DemoApplication.class, args);    }}

package com.example.demo.Controller;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;/** * @ClassName TestController * @Description: TODO * @Author java * @Date 2020/6/10 * @Version V1.0 **/@Controller@RequestMapping("/test")public class TestController {    @RequestMapping("hello")    @ResponseBody    public String  getTest(){        return "Hello World ,This is  Test";    }}

最简单的SpringBoot Demo创建完成了，项目结构如下：

启动项目后访问

127.0.0.1:8888/test/hello

浏览器返回信息如下：
