下面开始整合(由于有点多就不一一介绍了)

配置sqlMapConfig.xml(空文件即可)

测试Dao

编写Bean

public class Bean {
 private String id;
  private String name;
    private String sort;
  get/set...
}

编写mapper.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="cn.chuang.mapper.Bean">

</mapper>
