  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

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