springboot笔记一：idea社区版本创建springboot项目的方式

社区idea 手动maven 创建springboot项目

创建之后修改pom.xml

xml 复制代码

<?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

java 复制代码

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);
    }
}
