JSP分页怎么实现

可以把要从数据库里查询出的数据条数用sql语句写出来。

int rowBegin=0;

if(page1)

rowBegin=10*(page-1); 10就是你要显示的行数

String sql="select top 10 * from table where id not in(select top+"+rowBegin+" id from table )";

按下页时直接传参就可以了

jsp 如何将查询结果实现分页,最好简单易懂…

jsp中分页最快捷的办法是用分页组件:

分页组件代码使用taglib实现的:

%@ tag language="java" pageEncoding="UTF-8"%

%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c"%

%@ attribute name="curIndex" type="java.lang.Long" required="true"%

%@ attribute name="pageSize" type="java.lang.Long" required="true"%

%@ attribute name="pagerRange" type="java.lang.Long" required="true"%

%@ attribute name="totalPage" type="java.lang.Long" required="true"%

%@ attribute name="formId" type="java.lang.String" required="true"%

%

long begin = Math.max(1, curIndex - pagerRange/2);

long end = Math.min(begin + (pagerRange-1),totalPage);

request.setAttribute("p_begin", begin);

request.setAttribute("p_end", end);

%

table class="pager"

tr

% if (curIndex!=1){%

tda href="javascript:gotoPage(1)"首页/a/td

tda href="javascript:gotoPage(%=curIndex-1%)"上一页/a/td

%}else{%

td class="disabled"a href="#"首页/a/td

td class="disabled"a href="#"上一页/a/td

%}%

c:forEach var="i" begin="${p_begin}" end="${p_end}"

c:choose

c:when test="${i == curIndex}"

td class="active"a href="#"${i}/a/td

/c:when

c:otherwise

tda href="javascript:gotoPage(${i})"${i}/a/td

/c:otherwise

/c:choose

/c:forEach

% if (curIndex!=totalPage){%

tda href="#"下一页/a/td

tda href="#"末页/a/td

%}else{%

td class="disabled"a href="javascript:gotoPage(%=curIndex+1%)"下一页/a/td

td class="disabled"a href="javascript:gotoPage(%=totalPage%)"末页/a/td

%}%

tda共${totalPage}页/a/td

td class="input_li"跳转到:input type="text" id="p_pageIndex" size="2" value="c:out value="${pageIndex}"/"/页 input type="button" id="gotoBtn" onclick="gotoPageByBtn()" value="GO"//td

td class="input_li" 每页:

select id="p_pageSizeSelect" onchange="gotoPage(%=curIndex%)"

option value="10" c:if test="${pageSize==10}"selected/c:if10条/option

option value="20" c:if test="${pageSize==20}"selected/c:if20条/option

option value="50" c:if test="${pageSize==50}"selected/c:if50条/option

/select

/td

/tr

/table

jsp中使用方法:

%@ taglib uri="/WEB-INF/tld/c.tld" prefix="c"%

%@ taglib uri="/WEB-INF/tld/fmt.tld" prefix="fmt"%

%@ taglib tagdir="/WEB-INF/tags" prefix="tags"%

jsp分页SQL以及java代码怎么写

CREATE PROCEDURE [up_ARCH_DCFJ_Paged]

@pagesize int, --每页显示的记录数

@pageindex int, --当前页索引,最小值为1

@RecordCount int output --总记录数,0时不统计结果记录

AS

SET NOCOUNT ON

DECLARE @indextable TABLE(rowid INT IDENTITY(1,1),nid INT)

INSERT INTO @indextable(nid) --将符合的记录插入到临时表中

SELECT [FileID]

FROM [ARCH_DCFJ]

ORDER BY [FileID] DESC

IF(@RecordCount0)

BEGIN

SELECT @RecordCount= Count(1) FROM @indextable

END

DECLARE @PageLowerBound INT

DECLARE @PageUpperBound INT

SET @PageLowerBound=(@pageindex-1)*@pagesize

SET @PageUpperBound=@PageLowerBound+@pagesize

SET ROWCOUNT @PageUpperBound--最多执行行数 若下面还有超过此值的行数,请注释此行

SELECT a.*

FROM [ARCH_DCFJ] a,@indextable t

WHERE a.[FileID]=t.nid and t.rowid@PageLowerBound and t.rowid=@PageUpperBound

request.setAttribute("count", aboutList.size());// 放置在request中

request.setAttribute("pageModel", pageModel);

request.setAttribute("page", pageModel.getPage());

jsp代码

a href="${pageuri}page=${pageModel.next}"下一页/a

/c:if

如有不懂可以找我QQ聊

求java web 利用结果集进行分页代码 servlet+jsp

以下是最简单的分页(一个方法搞定):

首先是方法:

//用于按照页数和每页显示的记录数进行图书查询

public List getBookList(int page,int pageSize)throws Exception{

List list=new ArrayList();

Connection conn=this.getConn();

String sql="select top "+page+" * from bookInfo " +

"where bookId not in" +

"(select top "+((pageSize-1)*page)+" bookId from bookInfo)";

PreparedStatement pstmt=conn.prepareStatement(sql);

ResultSet rs=pstmt.executeQuery();

while(rs.next()){

//每条数据对应一个实体类

BookInfo book=new BookInfo();

book.setBookId(rs.getInt("bookId"));

book.setBookName(rs.getString("bookName"));

book.setBookType(rs.getString("bookType"));

book.setBookStatus(rs.getString("bookStatus"));

list.add(book);

}

this.closeAll(conn, pstmt, rs);

return list;

}

2:JSP页面代码:

%@ page language="java" import="java.util.*,entity.*,operator.*" pageEncoding="gbk"%

html

head

/head

body

table border="1"

tr

td width="150"图书名称/td

td width="100"类别/td

td width="100"状态/td

/tr

%

request.setCharacterEncoding("gbk");

int pageNum=1;

String pageStr=request.getParameter("pageNum");

if(pageStr==null){

pageNum=1;

}else{

pageNum=Integer.parseInt(pageStr);

}

Operator o=new Operator();

List list=o.getBookList(6,pageNum);

for(int i=0;ilist.size();i++){

BookInfo book=(BookInfo)list.get(i);

%

tr

td%=book.getBookName() %/td

td%=book.getBookType() %/td

td%=book.getBookStatus() %/td

/tr

%

}

%

tr

td colspan="3"a href="infoList.jsp?pageNum=%=pageNum==1?pageNum:pageNum-1%"上一页/a ||

a href="infoList.jsp?pageNum=%=list.size()6?pageNum:pageNum+1 %"下一页/a/td//二元运算符,相当于if判断 上一页时如果当前页=1为true,就是当前页,否则还可以减1

//下一页如果当前页的size小于你的每一页设置的条数为true,那么就是是当前页,否则就+1;
