这篇文章主要讲如何使用Maven快速搭建SpringMVC+Spring+ mybatis项目

Maven的安装与配置以及创建一个web项目可以看下面这篇博文

[Java框架基础教程 : Maven安装与配置以及在IDEA中使用Maven创建一个web项目][Java_ _ Maven_IDEA_Maven_web]

一.创建一个Maven项目,将Create from archetype(原型)勾选上

![70][]

然后next

![70 1][]

然后next

![70 2][]

![70 3][]

接下来点击Finish,等待maven下载所需的依赖包,项目就已经搭建好了

![70 4][]

二.配置SSM环境

1.修改项目目录

![70 5][]

2.配置相关配置文件
