　　java 类，写一个class继承这个抽象类

public abstract class AbstractPageForm<T extends AbstractPageForm<T>> implements Serializable {

private static final long serialVersionUID = 1L;

/**
* @Description 页码为首页
*/
@DefaultValue("1")
@QueryParam("pageNum")
protected int pageNum = 1;
/**
* @Description 每页显示数量，默认为10
*/
@DefaultValue("10")
@QueryParam("pageSize")
protected int pageSize = 10;

public int getPageNum() {
return pageNum;
}

public void setPageNum(int pageNum) {
this.pageNum = pageNum;
}

public int getPageSize() {
return pageSize;
}

public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}

/**
* @Title enablePaging
* @Description 启用分页
* @return
*/
@SuppressWarnings("unchecked")
public final T enablePaging() {
PageHelper.startPage(pageNum, pageSize);
return (T) this;
}

}

　　mapper.xml (CourseForm继承了AbstractPageForm的抽象类)

<?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="com.*.*DAO" >
<resultMap id="BaseResultMap" type="com.*.Class" >
<id column="id" property="id" jdbcType="INTEGER" />

</resultMap>

<select id="selectCourseList" resultMap="BaseResultMap" parameterType="com.*.form.CourseForm" >
select
<include refid="Base_Column_List" />
from TABLE_NAME
</select>

</mapper>

　　分页类示例：

@Override
public PageInfo<Class> queryList(CourseForm courseForm) {
　　　　　　　　//Class需要替换成自己的类
List<Class> selectList = organizationDAO.selectList(courseForm.enablePaging());
PageInfo<Class> pageInfo = new PageInfo<Class>(selectList);
return pageInfo;
}

　　pageInfo,POM配置

<groupId>com.github.pagehelper</groupId>
<artifactId>pagehelper</artifactId>
<version>4.1.5</version>
