1\_创建maven项目导入相关依赖

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

![b59888110d984d31c8c42058cdc5ea59.png][]

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

![d86234a43c6b574f674f9efaaed13a7a.png][]

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

![d7882028de3c2dc80b14bf9294cfc9d8.png][]

输入groupid和aitifactid 然后finish

![993c82fe9727682a30d4611383131fb0.png][]

检查项目目前在磁盘上的存放路径 然后next

![4aa1e05a5928e3e0d664fb05bd7072b4.png][]

检查项目目录结构是否有缺失

MyBatis官网说明文档 https://mybatis.org/mybatis-3/zh/index.html

在pom.xml中导入MyBatis相关依赖jar文件

安装lombok插件后,重启idea
