1. 导入pom依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.example</groupId>
    <artifactId>SpringBoot</artifactId>
    <version>1.0-SNAPSHOT</version>
    <modules>
        <module>Boot-demo01</module>
    </modules>
    <packaging>pom</packaging>

    <!-- 此项目继承的项目 -->
    <!-- starter-parent里面管理了boot所有的starter -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.3.RELEASE</version>
        <relativePath />
    </parent>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

    <!--打包插件  可以打成jar包-->
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

2. 创建主类

通过@SpringBootApplication来定义

package com.c21w;

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

//主程序的入口
@SpringBootApplication
public class Demo01SpringApplication {
    public static void main(String[] args) {
        //调用
        SpringApplication.run(Demo01SpringApplication.class,args);
    }
}

3. 运行~
