jsp页面数据分页模仿百度分页效果(实例讲解)

废话不多说，直接上代码

请根据自己的项目、包名修改

<%@page import="web09.shop.DBUtil"%>
<%@page import="java.sql.ResultSet"%>
<%@page import="java.sql.PreparedStatement"%>
<%@page import="java.sql.Connection"%>
<%@ page language="java" pageEncoding="UTF-8"%>

  rs1.next();
  int recordCount = rs1.getInt(1);   //记录总数
  int pageSize = 10;          //每页记录数
  int start=1;            //显示开始页

  int pageCount = recordCount%pageSize==0 ? recordCount/pageSize : recordCount/pageSize+1;
