Spring初学 - 2.通过MAVEN构建Spring项目

1. 安装Maven

1.1 官网下载Maven

1.2 解压并配置环境变量

 

 并将maven的bin目录添加到path

2. Maven仓库配置

2.1 在配置文件（apache-maven-3.8.5\conf\settings.xml）添加配置

<!-- maven本地仓库的位置  --> 
<localRepository>F:\MavenRepo</localRepository>

<!--注释源镜像，配置阿里云镜像仓库  -->
<mirror>
    <id>aliyunmaven</id>
    <mirrorOf>*</mirrorOf>
    <name>阿里云公共仓库</name>
    <url>https://maven.aliyun.com/repository/public</url>
</mirror>

<repository>
    <id>spring</id>
    <url>https://maven.aliyun.com/repository/spring</url>
    <releases>
        <enabled>true</enabled>
    </releases>
    <snapshots>
        <enabled>true</enabled>
    </snapshots>
</repository>

3. idea使用

3.1 配置maven

 

 3.2 创建mvn-web项目，执行mvn的版本，配置和仓库路径

4. 编写简单的Spring代码

 4.1 目录结构

 

 

 4.2 各个文件的内容
