Spring3+ibatis (SQL Server)+pager-taglib.tld查询分页的实现

pager-taglib分页开始~
查了好多关于分页的技术，最终选定以下方法实现~

1.首先下载jar包：pager-taglib.jar，pager-taglib.jar放在WEB-INF/lib目录下；

下载地址：http://download.csdn.net/detail/jeofey/8641287

2.将pager-taglib.tld文件放在WEB-INF目录下,pager-taglib.tld文件的内容见文章末尾；

3.只粘贴实现分页的关键部分

jsp中：

[html] view
plaincopy

标签库：

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>

<%@ taglib uri="http://java.sun.com/jsp/jstl/fmt" prefix="fmt"%>

<%@taglib uri="http://jsptags.com/tags/navigation/pager" prefix="pg" %>



实现分页用的几个变量：

<%

int currentPage = Integer.parseInt((String)request.getAttribute("page"));

int pageSize=25;

int resultCount = Integer.parseInt((String)request.getAttribute("resultCount"));

int pageCount=((resultCount - 1)/pageSize) + 1;

currentPage=Math.min(currentPage, pageCount);

int offset=(currentPage -1) * pageSize;

int totalpage = (resultCount % pageSize == 0) ? resultCount / pageSize

: (resultCount / pageSize) + 1;

%>



分页标记开始(为了显示清晰，放在div里面)：

<div>

<!-- 分页标记开始 -->

<ul style="float:right">

<pg:pager

items="<%= resultCount %>"

offset="<%= offset %>"

index="center"

maxPageItems="<%=pageSize%>"

maxIndexPages="10"

isOffset="false"

export="currentPageNumber=pageNumber"

scope="request">

<pg:index export="totalItems=itemCount">

<% if(((Integer)currentPageNumber).intValue() != 1) { %>

<pg:first>

<li><a href="/PageProject/directcity/alllist/tj/<%= pageNumber %>.html">首页</a></li>

</pg:first>

<%}%>

<pg:prev>

<li><a href="/PageProject/directcity/alllist/tj/<%= pageNumber %>.html">上一页</a></li>

</pg:prev>

<pg:pages>

<% if(pageNumber == currentPageNumber) { %>

<li class="ifpon"><span><%= pageNumber %></span></li>

<% } else { %>

<li><a href="/PageProject/directcity/alllist/tj/<%= pageNumber %>.html"><%= pageNumber %></a></li>

<% } %>

</pg:pages>

<pg:next>

<li><a href="/PageProject/directcity/alllist/tj/<%= pageNumber %>.html">下一页</a></li>

</pg:next>

<% if(((Integer)currentPageNumber).intValue() != totalpage) { %>

<pg:last>

<li><a href="/PageProject/directcity/alllist/tj/<%= pageNumber %>.html">尾页</a></li>

</pg:last>

<%}%>

<pg:page export="firstItem, lastItem"></pg:page>

</pg:index>

</pg:pager>

</ul>

<!-- 分页标记结束 -->



</div>

SQL语句：

[sql] view
plaincopy

例1 ：select * from (

select top pageSize * from (

select top offset + pageSize *

from ( select * from 表1 union all select * from 表2 union all select * from 表3) ) result

where 条件

order by 排序字段 desc )a order by 排序字段 asc )b order by 排序字段 desc

例2： select top pageSize * from 表 where 主键 not in(select top (currentPage-1)*pageSize news_id from 表)

最后插张调试结果的图片：



pager-taglib.tld文件内容：

[plain] view
plaincopy

<info>

The Pager Tag Library is the easy and flexible way to implement paging of

large data sets in JavaServer Pages (JSP). It can emulate all currently

known paging styles with minimal effort. It also includes re-usable index

styles that emulate the search result navigators of popular web sites

such as Google[sm], AltaVista® and Yahoo!. The Pager Tag Library does most

of the work for you by dynamically organizing your data set into pages and

generating a browsable index with virtually any look desired.
