數據庫很簡單就一張表
表字段有：
id，主鍵，自動增長
name 組名
直接貼代碼;
<%@ page language="java" import="java.sql.*,java.util.*" pageEncoding="gbk"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
String pageNowStr=request.getParameter("pageNow"); //當前是第幾頁
int pageNow=1;
if(pageNowStr!=null){
pageNow=Integer.valueOf(pageNowStr);
}
%>

out.print("<a href=sqlserver.jsp?pageNow="+(pageNow-1)+">上一頁</a> ");
}
for(int i=pageNow;i<pageNow+3;i++){
if(i<=pageCount) //使其不超過總頁數
out.print("<a href=sqlserver.jsp?pageNow="+i+">"+i+"</a> ");

</body>
</html>
效果如下;
