mybatis-generator 代码自动生成工具（maven方式）

由于MyBatis属于一种半自动的ORM框架，所以主要的工作将是书写Mapping映射文件，但是由于手写映射文件很容易出错，mybatis-gennerator插件帮我们自动生成mybatis所需要的dao、bean、mapper xml文件。

这里主要通过eclipse工具，来讲解实现;

1、建表语句

CREATE TABLE `user` (

  `id` int(11) NOT NULL AUTO_INCREMENT,

  `name` varchar(100) DEFAULT NULL,

  PRIMARY KEY (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

2、新建测试工程

选择maven工程

选择create a simple project就行

点击finish，测试项目就建完了

3、在maven配置文件pom.xml中添加依赖
