# IntelliJ IDEA创建Spring SpringMVC MyBatis整合Maven项目，并提交至Github #

本文小博将写一篇IDEA创建SSM+Maven整合项目，并提交至Github的教程。较为基础，大神勿喷。原创博客，转载请注明来源。

①新建Maven项目，如下图顺序。第三张图片中，添加一个参数archetypeCatalog=internal，表示仅使用内部元数据，不用这个参数创建Maven项目会很慢哦。其他起名字什么的大家大家随意，就不一一解释了。

![2][]  
![3][]  
![4][]

②将Java文件夹标记为源码目录，然后创建各种MVC模式对应的包  
![5][]

③如下图，创建配置文件，然后进行各种配置文件的编写。后面贴出我的代码，篇幅太大就不逐一解释了，以后有时间再详细拉出来写写。
