一、IDEA基于maven创建springMVC项目

一、打开IDEA，新建项目，选择Maven，选中界面右侧复选框，点击maven-archetype-webapp，如下图所示

二、填写GroupId和ArtifactId

三、属性配置，点击“+”，Name：archetypeCatalog，value：internal

四、设置项目地址、项目名称，项目名与第二部设置的ArtifactId相同，点击Finish完成创建。

五、IDEA开始创建项目，点击底部弹出的Enable Auto-Import，开启自动导入

六、创建目录，并对目录进行标注，否则无法创建新的包和java类等文件

七、配置Maven的pom.xml，参考公司的项目，dependencies增加如下内容

添加完成之后，等待maven将这些jar下载完毕，IDEA界面External Library部分导入了很多文件
