社区idea 手动maven 创建springboot项目

创建之后修改pom.xml

<?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>com.student</groupId><artifactId>Maven-SpringBoot</artifactId><version>1.0-SNAPSHOT</version><packaging>jar</packaging><name>Maven-SpringBoot</name><!--1.spring-boot-starter-parent自动引入springboot中最基础的组件，所有springboot项目都要依赖它进行构建--><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.7.8-SNAPSHOT</version></parent><properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding></properties><dependencies><!--2.引入springboot依赖，spring-boot-starter-web表示在项目中增加支持javaweb的功能，版本信息已经在parent中定义--><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>junit</groupId><artifactId>junit</artifactId><version>3.8.1</version><scope>test</scope></dependency></dependencies><!--3.定义springboot的打包方式，spring-boot-maven-plugin可以在打包时自动将所有类和资源打包成一个独立可运行的jar包--><build><!--打包指定名称--><finalName>mevanSpringBoot</finalName><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId></plugin></plugins></build>
</project>

版本号可以修改，刷新之后创建启动类：SpringBootApplicationMevan

package com.student;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;/*** Hello world!**/
@SpringBootApplication
public class SpringBootApplicationMevan {public static void main( String[] args ){System.out.println( "Hello World!" );SpringApplication.run(SpringBootApplicationMevan.class, args);}
}
