纯JSP分页代码之sqlserver2005/2008

系统 2258 0

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：


<!-- {cps..0}--> <% @pagelanguage = " java " contentType = " text/html;charset=UTF-8 "
pageEncoding = " UTF-8 " %>
<%
// 连接字符串
Stringurl = " jdbc:sqlserver:// " + Globals.Server
+ " ;databaseName= " + Globals.DbName;
Class.forName(Globals.driverName).newInstance();
Connectionconnection = DriverManager.getConnection(url,
Globals.username,Globals.pwd);
Statementstatement = 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 );

用到的类文件：Globals.java


<!-- {cps..1}--> /***/ /**
*
*/
package net.data.util;

/***/ /**
* @author Administrator
*
*/
public class Globals {
public static Stringusername = " sa " ;
public static Stringpwd = " sa " ;
public static StringDbName = " TestData " ;
// publicstaticStringServer="192.168.30.6";
public static StringServer = " 192.168.44.2:1433 " ;
public static StringPort = " 1433 " ;

public static StringdriverName = " com.microsoft.sqlserver.jdbc.SQLServerDriver " ;
// publicstaticStringconnectionURL{
//
// return"jdbc:sqlserver: // "+Server+":"+Port+";databaseName="+DbName;
// }


}

效果如图：
