%@ page import="javang.*" import="java.sql.*" import="java.util.*" contentType="text/;charset=GB2312"%

%
int PageSize = 10;设置一页显示的记录数
int PageNum = 1; 初始化页码=1
int PageNumCount = (136+PageSize-1) / PageSize;记算总页数
计算要显示的页码
String strPageNum = request.getParameter("page");取得href提交的页码
if(strPageNum==null){ 表明在QueryString中没有page这一个参数，此时显示第一页数据
PageNum = 1;
}
