1.创建一个分页组建PageModel.java

package com.zsw.util;

import java.util.List;
/**
 * 分页组建
 * @author zsw
 * 时间：2009年2月13日11:11:35
 */
public class PageModel {

  private int pageNo;     //当前页数
   
  private int pageSize=15;    //每页显示多少条数据
  
  private int totalRecords;   //总记录
  
  private List list;      //获取结果集
  
  /**
   * 获取总记录数
   * @return
   */
  public int getTotalPages(){
    return (totalRecords+pageSize-1)/pageSize;
  }
  
  /**
   * 获取首页
   * @return
   */
  public int getTopPage(){
    return 1;
  }
  
  /**
   * 获取上一页
   * @return
   */
  public int getUpPage(){
    if(pageNo<=1){
      return 1;
    }
    return pageNo-1;
  }
  
  /**
   * 获取下一页
   * @return
   */
  public int getNextPage(){    
    if(pageNo>getTotalPages()){
      return getTotalPages()==0?1:getTotalPages();
    }
    return pageNo+1;
  }
  
  /**
   * 获取最后一页
   * @return
   */
  public int getBottomPage(){
    return getTotalPages()==0?1:getTotalPages();
  }
  
  
  
  
  
  
  
  public int getPageNo() {
    return pageNo;
  }

  public void setPageNo(int pageNo) {
    this.pageNo = pageNo;
  }

  public int getPageSize() {
    return pageSize;
  }

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

  public int getTotalRecords() {
    return totalRecords;
  }

  public void setTotalRecords(int totalRecords) {
    this.totalRecords = totalRecords;
  }

  public List getList() {
    return list;
  }

  public void setList(List list) {
    this.list = list;
  }
  
  
  
}

2.用户dao层

package com.zsw.dao.impl;

import java.util.List;

import org.hibernate.Session;

import com.zsw.dao.UserDAO;
import com.zsw.entity.HibernateSessionFactory;
import com.zsw.util.PageModel;

public class UserDAOImpl implements UserDAO {
  
  /**
   * 获取所有的集合
   */
  public PageModel getAll(int pageNo, int pageSize) {
    
    Session session = HibernateSessionFactory.getSession();
    session.beginTransaction();
    
    List list = session.createQuery("from TUser")
        .setFirstResult((pageNo-1)*pageSize)
        .setMaxResults(pageSize)
        .list();
    
    int count = (Integer)session.createQuery("select count(*) from TUser").uniqueResult(); //获取总记录数
    
    
    System.out.println(pageNo);
    PageModel pageModel = new PageModel();
    pageModel.setList(list);
    pageModel.setPageNo(pageNo);
    pageModel.setPageSize(pageSize);
    pageModel.setTotalRecords(count);
    
    session.getTransaction().commit();
    
    return pageModel;   
  }

}

3.页面

<html:html lang="true">
  <head>
    <title>userList.jsp</title>
    <mce:script type="text/javascript"><!--
      function getTopPage(){
        window.location.href="user.do?op=getList&pageSize={userForm.pageSize}&pageNo=${pagemodel.topPage}";
      }
      function getNextList(){
        window.location.href="user.do?op=getList&pageSize={userForm.pageSize}&pageNo=${pagemodel.nextPage}";
      }
      function getUpPage(){
        window.location.href="user.do?op=getList&pageSize={userForm.pageSize}&pageNo=${pagemodel.upPage}";
      }
      function getBottomPage(){
        window.location.href="user.do?op=getList&pageSize={userForm.pageSize}&pageNo=${pagemodel.bottomPage}";
      }
    
// --></mce:script>
  </head>
  <body>
    <logic:iterate id="user" name="list">
      ${user.userName }<br>
    </logic:iterate>
   <br>
   <div style="border:1px solid red;" mce_style="border:1px solid red;" align="center" >
    <input type="button" value="首页" οnclick="getTopPage()">
    <input type="button" value="上一页" οnclick="getUpPage()">
    <input type="button" value="下一页" οnclick="getNextList()">
    <input type="button" value="最后一页" οnclick="getBottomPage()">
   </div> 
   总记录数：${pagemodel.totalRecords } |
   总页数：${pagemodel.totalPages } |
   当前页数：${pagemodel.pageNo } |
   每页显示页数：${pagemodel.pageSize }
  </body>
</html:html>
