纯JSP分页代码之sqlserver2005/2008
昨天看到一篇《纯JSP分页代码》的文章，是用于mysql，稍微修改下，用于Sqlserver2005/2008，没有异常处理。没有考虑性能等。
昨天看到一篇《纯JSP分页代码》的文章，是用于mysql，稍微修改下，用于Sqlserver2005/2008，没有异常处理。没有考虑性能等。
现将代码贴出，以供初学者参考：
注：邀月使用环境Eclipse 3.4.2+Tomcat 6.18+Sqlserver2005 sp3调试成功。
页面pagelistDemo.jsp内容：
Code
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><% //连接字符串 String url = "jdbc:sqlserver://" + Globals.Server + ";databaseName=" + Globals.DbName; Class.forName(Globals.driverName).newInstance(); Connection connection = DriverManager.getConnection(url, Globals.username, Globals.pwd); Statement statement = connection.createStatement(); //每页显示记录数 int PageSize = 10; int StartRow = 0; //开始显示记录的编号 int PageNo = 0;//需要显示的页数 int CounterStart = 0;//每页页码的初始值 int CounterEnd = 0;//显示页码的最大值 int RecordCount = 0;//总记录数; int MaxPage = 0;//总页数 int PrevStart = 0;//前一页 int NextPage = 0;//下一页 int LastRec = 0; int LastStartRecord = 0;//最后一页开始显示记录的编号 //获取需要显示的页数，由用户提交 if (request.getParameter("PageNo") == null) 
{ //如果为空，则表示第1页
if (StartRow == 0) {
PageNo = StartRow + 1; //设定为1
} } else { PageNo = Integer.parseInt(request.getParameter("PageNo")); //获得用户提交的页数 StartRow = (PageNo - 1) * PageSize; //获得开始显示的记录编号
} //因为显示页码的数量是动态变化的，假如总共有一百页，则不可能同时显示100个链接。而是根据当前的页数显示 //一定数量的页面链接 //设置显示页码的初始值!! if (PageNo % PageSize == 0) { CounterStart = PageNo - (PageSize - 1); } else { CounterStart = PageNo - (PageNo % PageSize) + 1; } CounterEnd = CounterStart + (PageSize - 1);%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><%@page import="net.data.util.Globals"%><%@page import="java.sql.ResultSet"%><%@page import="java.sql.DriverManager"%><%@page import="java.sql.Connection"%><%@page import="java.sql.Statement"%><element><html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>分页显示记录</title><link rel="stylesheet" href="style.css" type="text/css"></head><% //获取总记录数 ResultSet rs = statement .executeQuery("select count(P_ID) from product"); rs.next(); RecordCount = rs.getInt(1); //取特定页数的数据 String strColumn = " P_ID,P_Name,LoginID,modTime,P_SingleIntro "; String strTable = " Product "; String strSort = " p_ID desc "; String PKID = "P_ID"; String strSql = ""; String strWhere = ""; String START_ID = Integer.toString((PageNo - 1) * PageSize + 1); String END_ID = Integer.toString(PageNo * PageSize); strSql = " SELECT " + strColumn + " FROM (SELECT ROW_NUMBER() OVER(ORDER BY " + strSort + ") AS rownum," + strColumn + " FROM " + strTable + " WITH(NOLOCK) " + strWhere + ") AS D WHERE rownum BETWEEN " + START_ID + " AND " + END_ID + " ORDER BY " + strSort; rs = statement.executeQuery(strSql); //获取总页数 MaxPage = RecordCount % PageSize; if (RecordCount % PageSize == 0) { MaxPage = RecordCount / PageSize; } else { MaxPage = RecordCount / PageSize + 1; }%><body class="UsePageBg"><table width="100%" border="0" class="InternalHeader"> <tr> <td width="24%"><font size=4>分页显示记录</font></td> <td width="76%"><font size=4><%="总共" + RecordCount + "条记录 - 当前页：" + PageNo + "/" + MaxPage%></font></td> </tr></table><br><table width="100%" border="0" class="NormalTableTwo"> <tr> <td class="InternalHeader">记录序号</td> <td class="InternalHeader">数据标识号</td> <td class="InternalHeader">产品名称</td> <td class="InternalHeader">作者</td> <td class="InternalHeader">提交时间</td> <td class="InternalHeader">简介</td> </tr> <% long i = 1; while (rs.next()) { long bil = i + (PageNo - 1) * PageSize; %> <tr> <td class="NormalFieldTwo"><%=bil%></td> <td class="NormalFieldTwo"><%=rs.getString(1)%></td> <td class="NormalFieldTwo"><%=rs.getString(2)%></td> <td class="NormalFieldTwo"><%=rs.getString(3)%></td> <td class="NormalFieldTwo"><%=rs.getString(4)%></td> <td class="NormalFieldTwo"><%=rs.getString(5)%></td> </tr> <% i++; } %></table><br><table width="100%" border="0" class="InternalHeader"> <tr> <td> <div align="center"> <% out.print("<font size=4>"); //显示第一页或者前一页的链接 //如果当前页不是第1页，则显示第一页和前一页的链接 if (PageNo != 1) { PrevStart = PageNo - 1; out.print("<a href=pagelistDemo.jsp?PageNo=1>第一页 </a>: "); out.print("<a href=pagelistDemo.jsp?PageNo=" + PrevStart + ">前一页</a>"); } out.print("["); //打印需要显示的页码 for (int c = CounterStart; c <= CounterEnd; c++) { if (c < MaxPage) { if (c == PageNo) { if (c % PageSize == 0) { out.print(c); } else { out.print(c + " ,"); } } else if (c % PageSize == 0) { out.print("<a href=pagelistDemo.jsp?PageNo=" + c + ">" + c + "</a>"); } else { out.print("<a href=pagelistDemo.jsp?PageNo=" + c + ">" + c + "</a> ,"); } } else { if (PageNo == MaxPage) { out.print(c); break; } else { out.print("<a href=pagelistDemo.jsp?PageNo=" + c + ">" + c + "</a>"); break; } } } out.print("]"); ; if (PageNo < MaxPage) { //如果当前页不是最后一页，则显示下一页链接 NextPage = PageNo + 1; out.print("<a href=pagelistDemo.jsp?PageNo=" + NextPage + ">下一页</a>"); } //同时如果当前页不是最后一页，要显示最后一页的链接 if (PageNo < MaxPage) { LastRec = RecordCount % PageSize; if (LastRec == 0) { LastStartRecord = RecordCount - PageSize; } else { LastStartRecord = RecordCount - LastRec; } out.print(":"); out.print("<a href=pagelistDemo.jsp?PageNo=" + MaxPage + ">最后一页</a>"); } out.print("</font>"); %> </div> </td> </tr></table><% rs.close(); statement.close(); connection.close();%></body></html>
用到的类文件：Globals.java
Code/** *//** * */package net.data.util;/** *//** * @author Administrator * */public class Globals { public static String username="sa"; public static String pwd="sa"; public static String DbName="TestData"; //public static String Server="192.168.30.6"; public static String Server="192.168.44.2:1433"; public static String Port="1433"; public static String driverName="com.microsoft.sqlserver.jdbc.SQLServerDriver";// public static String connectionURL {// // return "jdbc:sqlserver://"+Server+":"+Port+";databaseName="+DbName;// }}
效果如图：
