Maven项目创建SpringBoot

一，用maven创建springboot
1,写父项目并导包
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.5.RELEASE</version>
</parent>

<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
</dependencies>
2，编写启动类
package com.qf;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class HelloMainApplication {
public static void main(String[] args) {
SpringApplication.run(HelloMainApplication.class,args);
}
}
