利用The Pager Tag Library 实现分页功能

1： 在应用服务器中，你所应用到项目的web-inf/web.xml中的<web-app>...</web-app> 标签中添加：

<taglib>

<taglib-uri>

http://jsptags.com/tags/navigation/pager //可以更改

</taglib-uri>

<taglib-location>

/WEB-INF/jsp/pager-taglib.tld //指明pager-taglib.tld存放的位置

</taglib-location>

</taglib>

2： 到http://jsptags.com/tags/navigation/pager/下载pager-taglib-2.0.war包，解压后可获得pager-taglib.jar，将其放到web-inf/lib/包下。pager-taglib.tld可以到/WEBINF/jsp/包下。

3：在所需要分页的jsp页面顶部添加：<%@ taglib uri="http://jsptags.com/tags/navigation/pager " prefix="pg" %>

4：

<% totalItems = list.size(); //接收到的list

String style = “simple“

Sing position = "both"; //top bottom

int maxPageItems ＝1； //每页显示数据的个数

int maxIndexPages = 4;//显示跳转页面的个数

String index = "center";

%>

<pg:pager

items="<%= totalItems %>"

index="<%= index %>"

maxPageItems="<%= maxPageItems %>"

maxIndexPages="<%= maxIndexPages %>"

export="offset,currentPageNumber=pageNumber"

scope="request">

<pg:param name="style"/>

<pg:param name="position"/>

<pg:param name="index"/>

<pg:param name="maxPageItems"/>

<pg:param name="maxIndexPages"/>

<input type="hidden" name="pager.offset" value="<%= offset %>">

<%-- warn if offset is not a multiple of maxPageItems --%>

<% if (offset.intValue() % maxPageItems != 0 &&

("alltheweb".equals(style) || "lycos".equals(style)) )

{

%>

<p>Warning: The current page offset is not a multiple of Max. Page Items.

<br>Please

<pg:first><a href="<%= pageUrl %>">return to the first page</a></pg:first>

if any displayed range numbers appear incorrect.</p>

<% } %>

// 显示跳转的jsp；

<% if ("top".equals(position) || "both".equals(position)) { %>

<pg:index><jsp:include page="paging-links.jsp" flush="true"/></pg:index>

<% } %>

<% for(int i = 0; i <size; i++ ){%>

<pg:item>

<td> <%= list.get(i)%></td> // 简单的显示数据；

</pg:item>

<%

}

%>

</pg:pager>

5. paging-links.jsp 如下：或者参照jsptags中的示范copy你所需要的显示格式

<%@ page session="false" %>

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

<table width=100% cellpadding=2 cellspacing=0 border=0 bgcolor=e3e9f8>

<tr><td><font face=arial size=2>&nbsp;<b>Matches</b></font>

</td><td align=right nowrap width=1%><font face=arial size=-1>

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

<pg:page export="first,last">

<%= first %> - <%= last %> of <%= total %>

</pg:page>

<pg:first export="url" unless="current">

&nbsp;<b><a href="<%= url %>">First Page</a></b>&nbsp;|

</pg:first>

<pg:prev export="url,first,last">

<% int prevItems = (last.intValue() - first.intValue()) + 1; %>

<b><a href="<%= url %>">Previous <%= prevItems %></a></b>

</pg:prev>

<pg:next export="url,first,last">

<% int nextItems = (last.intValue() - first.intValue()) + 1; %>

|&nbsp;<b><a href="<%= url %>">Next <%= nextItems %></a></b>

</pg:next>

&nbsp;&nbsp;</font></td></tr>

</table>

</pg:index>
