1、New Project，选择 spring Initializr，下一步
2、设置maven三坐标，jdk version为自己的jdk版本，下一步
3、以下是可以选择的maven依赖，这里我们选择 Web->Spring Web,创建工程

4、springboot为我们自动创建了目录，截图如下
5、springboot为我们自动创建了初始文件:SpringBootDemoApplication.java、SpringBootDemoApplicationTests.java、application.properties(文件内容为空)、pom.xml等,罗列如下:
package com.yl.example.springbootdemo; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class SpringBootDemoApplication { public static void main(String[] args) { SpringApplication.run(SpringBootDemoApplication.class, args); } }
package com.yl.example.springbootdemo; import org.junit.jupiter.api.Test; import org.springframework.boot.test.context.SpringBootTest; @SpringBootTest class SpringBootDemoApplicationTests { @Test void contextLoads() { } }
