忍不住了，凑凑热闹，我也来秀一下我的分页类

看到javaeye上分页的帖子实在太多了，上半年，做网站，分页让我烦恼，一气之下，写了个可以通用的分页累，今天在单位，没源代码，先传jar，明天再传源代码，我也show下我的分页类
这是下载地址
http://code.google.com/p/javaman/downloads/list
简单说明
为了保险起见，绝对标准的OO设计
Page 接口 定义分页接口
AbstractPage Page接口的默认实现，实现了大多数操作
defaultPageIMpl 实体类 【如果不满意我的实现，自己可以实现】
用法
实例话一个DefaultPageImpl
默认构造， DefaultPageImpl(); 默认每页显示10条记录
带参数构造 DefaultPageImpl(int rowInPage) 传入每页的显示数目
用法， setRowCount(int c) 需要传入 记录总行数
       setPageIndex(int index) 页码索引
getStartIndex() 返回抓取记录的起始索引 
getOffset()    返回抓取的行数

==============================================================
就这么简单，至于mysql 实际上就是 想办法取得 limit x,y 的xy值
其他数据库没研究过，怎么分页，欢迎大家拍砖

楼主，你的源码呢？

Page

  package net.myweb.tool;

public abstract interface Page
{
  //设置当前页索引
  public abstract void setPageIndex(int paramInt);
  //得到当前页索引
  public abstract int getPageIndex();
  //设置总记录数
  public abstract void setRowCount(int paramInt);
  
  public abstract int getRowCount();
  //设着每页显示的行数
  public abstract void setRowInPage(int paramInt);

  public abstract int getRowInPage();

  public abstract int getStartIndex(int paramInt);
  
  //得到本页开始索引
  public abstract int getStartIndex();
  //得到总页数
  public abstract int getPageCount();
  //判断是否有前页
  public abstract boolean hasPrevious();
  //判断是否有后页
  public abstract boolean hasNext();
}

package net.myweb.tool;

import org.apache.log4j.Logger;

public class AbstractPage
  implements Page
{
  protected final Logger logger;
  private int _rowCount;
  private int _rowsInPage;
  private int _pageIndex;
  private int _pageCount;

  public AbstractPage(int rowCount)
  {
    this.logger = Logger.getLogger(super.getClass());

    this._rowsInPage = 10;
    this._pageIndex = 0;

    int base = this._rowCount / this._rowsInPage;
    if (this._rowCount % this._rowsInPage == 0)
      this._pageCount = base;
    else
      this._pageCount = (base + 1);
  }

  public AbstractPage()
  {
    this(10);
  }

  public int getPageIndex() {
    if (getPageCount() == 0)
      this._pageIndex = 1;
    if ((this._pageIndex > getPageCount()) && (getPageCount() != 0))
      this._pageIndex %= getPageCount();
    if ((this._pageIndex > getPageCount()) && (getPageCount() == 0))
      this._pageIndex = 1;
    if (this._pageIndex <= 0)
      this._pageIndex = 1;
    return this._pageIndex;
  }

  public int getRowCount()
  {
    return this._rowCount;
  }

  public int getRowInPage()
  {
    return this._rowsInPage;
  }

  public int getStartIndex(int pageIndex) {
    if ((pageIndex <= 0) || (pageIndex >= getRowCount()))
      return 0;

    return ((pageIndex - 1) * this._rowsInPage);
  }

  public void setPageIndex(int curent)
  {
    this._pageIndex = curent;
  }

  public void setRowCount(int rowCount)
  {
    this._rowCount = rowCount;
  }

  public void setRowInPage(int rows)
  {
    if (rows > 0)
      this._rowsInPage = rows;
  }

  public int getPageCount()
  {
    int base = this._rowCount / this._rowsInPage;
    if (this._rowCount % this._rowsInPage == 0)
      this._pageCount = base;
    else
      this._pageCount = (base + 1);
    return this._pageCount;
  }

  public boolean hasNext() {
    return (getPageIndex() != getPageCount());
  }

  public boolean hasPrevious()
  {
    return (getPageIndex() != 1);
  }

  public int getStartIndex() {
    return getStartIndex(getPageIndex());
  }
}

package net.myweb.tool;

public class DefaultPageImp extends AbstractPage
{
  public DefaultPageImp(int rowperpage)
  {
    super(rowperpage);
  }
}

对应的三个类，都很简单，功能一看就懂
