但凡是框架,使用都是分三步走

1导入jar文件,maven

2处理配置文件

3开发业务代码

先创建一个空项目,用于存放后面Mybatis相关项目模块

项目名为mybatisAll即可

这里不显示项目名 没关系,如果想看到项目名,可以close项目后,再次open即可

关闭项目

再次open

项目名就显示了

接下来设置maven为我们自己安装的,不用idea自带的(当然用自带的也行)

在当前项目中创建模块

选择maven项目 next

输入groupid和aitifactid 然后finish

检查项目目前在磁盘上的存放路径 然后next

![0a0ddd9aefafac6d1f8a4c8189465cac.png][]

检查项目目录结构是否有缺失

在pom.xml中导入MyBatis相关依赖jar文件
