上一篇 Spring Boot 2.0.2 教程 - Hello World - 01
1.开始啦
2.在左侧菜单中选择 Spring Initializr ,右侧 Project SDK使用1.8,如果没有的话点击右侧New...按钮
3.填写自己的包名，项目名称等，这里我全部保持默认
4.在这个选择依赖的界面窗口，选择Web里的Web即可
5.接下来就等待项目初始化，下载相关依赖了
如果要更新maven项目配置，可在File->Settings中找到maven来更换你的仓库地址
如果在依赖下载过程中出现错误，可以点击项目右键->Maven->Reimport
6.新建测试controller,目录及内容参考如下
HelloController.java
package com.example.demo.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* Created by Administrator on 2018/7/4.
*/
@RestController
public class HelloController {
@RequestMapping("/hello")
public String print(){
return "Hi Spring Boot2.0.2 ";
}
}7.启动，在DemoApplication.java中右键Run DemoApplication
