jsp实现读取数据库数据分页显示

<%@ page language="java" pageEncoding="gb2312" %>
<%@ page contentType="text/html;charset=gb2312" %>
<%request.setCharacterEncoding("gb2312");%>
<%@ page import="java.util.*,java.lang.*,java.sql.*,javax.naming.*,javax.sql.*" %>
<%@ page errorPage="error.html" %>



<%Connection con=null;
  Statement stmt=null;
  ResultSet rs=null;
  int pageSize,rowCount,pageCount,curPage;
  pageSize=5;
  pageCount=1;
  String strPage=request.getParameter("page");
  if(strPage==null) curPage=1;
  else{
    curPage=Integer.parseInt(strPage);//通过参数来定当前页面
    if(curPage<1) curPage=1;
    }
%>
<%try{
  InitialContext ctx=new InitialContext();
  DataSource ds=(DataSource)ctx.lookup("java:comp/env/MySqlDS");
  con=ds.getConnection();
  stmt=con.createStatement();
  rs=stmt.executeQuery("select * from infos");
  rs.last();
  rowCount=rs.getRow();
  pageCount=(rowCount+pageSize-1)/pageSize;
  if(curPage>pageCount) curPage=pageCount;
  }catch(SQLException e){
    System.out.println(e.toString());
  }
%>

页次：<%=curPage %>/<%=pageCount %>页     <%=pageSize %>条/页


<%if(pageCount>0) rs.absolute((curPage-1)*pageSize+1);
int i=0;
while(i

<%
rs.next();
i++;
} %>

Number

<%=rs.getString(1)%>
<%=rs.getString(2)%>
<%=rs.getString(3)%>
<%=rs.getString(4)%>
<%if(curPage>1){ %>
上一页<%} %>
<%if(curPage
下一页<%} %>

<%rs.close();
