使用IDEA和gradle搭建Spring MVC和MyBatis开发环境
Spring MVC 环境搭建

intellij+gradle spring环境搭建

第一次可以参考上面的环境搭建文章，写的很好。
这里新建一个project：

GroupID是项目组织唯一的标识符，实际对应[Java]的包结构,就是main目录里java的目录结构。一般GroupID就是填com.company.appname,这样子。

ArtifactID就是项目的唯一的标识符，实际对应项目的名称，就是项目根目录的名称。例如（zhifubao,weixin当然用英文更好）

选择gradle的来源，可以用自己下载的gradle，也可以使用IDEA内建的gradle版本：

选择项目存放的目录：

添加jar包进lib中，这里我比较懒，直接都加进去，自己可以根据需要添加，如图
