userMapper,User,UserMapper.xml这三个文件是mybatis-generator自动生成的,自己百度就好

使用方法: (1)打开dos命令窗口,进入到该目录下,配置好generatorConfig.xml后,运行命令:

java -jar mybatis-generator-core-1.3.2.jar -configfile generatorConfig.xml -overwrite

(2)拷贝文件到项目对应位置

jar包链接:http://down.51cto.com/data/2302826

项目源码链接: 待放

不推荐大家直接看源码,自己参考以上代码,看看能否自己搭出来
