之前自己写了一个分页自定义标签:OssPageSplitTag

第一步:  需要建立OssPageSplitTag类.

package com.dianziq.wenda.admin.tag;

import java.io.IOException;

import javax.servlet.jsp.JspException;
import javax.servlet.jsp.tagext.BodyTagSupport;

import org.apache.commons.lang3.StringEscapeUtils;


import com.dianziq.wenda.admin.base.collection.PageSplit;

/**
 * 后台分页的标签库
 * 
 * @author Vernon.Chen
 */
public class OssPageSplitTag<T> extends BodyTagSupport {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	private String data = "pageSplit";// 数据集合名字

	private String href; // 连接地址

	private StringBuffer output; // 页面输出

	public String getData() {
		return data;
	}

	public void setData(String data) {
		this.data = data;
	}

	public String getHref() {
		return href;
	}

	public void setHref(String href) {
		this.href = href;
	}

	@Override
	public int doStartTag() throws JspException {
		try {
			output = new StringBuffer();
			hander();
			this.pageContext.getOut().write(output.toString());
		} catch (IOException e) {
			e.printStackTrace();
		}
		return SKIP_BODY;
	}

	@SuppressWarnings({ "unchecked" })
	private void hander() {
		// 转义href
		href = StringEscapeUtils.escapeHtml4(href);
		href = StringEscapeUtils.escapeEcmaScript(href);
		
		// 如果URL不包含? 则添加?
		if (href.indexOf("?") < 0) {
			href += "?";
		}
		if (href.endsWith("?") || href.endsWith("&amp;")) {
			href += "pageIndex=";
		} else {
			href += "&amp;pageIndex=";
		}
		PageSplit<T> pageSplit = (PageSplit<T>) this.pageContext.getRequest()
				.getAttribute(data);
		if (pageSplit != null) {
			StringBuffer page = new StringBuffer();
			page.append("<div class=\"pagination\">");
			page.append("<ul>");
			page.append("<li><a href=\"" + href + 1 + "\" title=\"首页\">&laquo; 首页</a></li>");
			page.append("<li><a href=\"" + href + pageSplit.getPrevPage() + "\" title=\"上一页\">&laquo; 上一页</a></li>");
			if (pageSplit.getTotalPage() <= 4) {// totalPage <=4 的时候
				for (int i = 1; i <= pageSplit.getTotalPage(); i++) {
					page.append("<li");
					if (pageSplit.getPageIndex() == i) {
						page.append(" class=\" active\" ");
					} else {
						page.append(" class=\"\" ");
					}
					page.append("><a href=\"" + href + i + "\" title=\"" + i + "\" >" + i + "</a></li>");
				}
			} else if (pageSplit.getTotalPage() > 4 && pageSplit.getTotalPage() <= 9) {// totalPage 在(4,9] 之间的时候
				int endPageIndex = pageSplit.getPageIndex() + 3 > pageSplit
						.getTotalPage() ? pageSplit.getTotalPage() : pageSplit
						.getPageIndex() + 3;
				for (int i = 1; i <= endPageIndex; i++) {
					page.append("<li");
					if (pageSplit.getPageIndex() == i) {
						page.append(" class=\" active\" ");
					} else {
						page.append(" class=\"\" ");
					}
					page.append("><a href=\"" + href + i + "\" title=\"" + i + "\" >" + i + "</a></li>");
				}
				if (pageSplit.getPageIndex() + 3 < pageSplit.getTotalPage()) {
					page.append("<li><a href=\"javascript:;\">...</a></li>");
				}
			} else {// totalPage 在(9,totalPage] 之间的时候
				if (pageSplit.getPageIndex() + 3 <= 9) {
					for (int i = 1; i <= pageSplit.getPageIndex() + 3; i++) {
						page.append("<li");
						if (pageSplit.getPageIndex() == i) {
							page.append(" class=\" active\" ");
						} else {
							page.append(" class=\"\" ");
						}
						page.append("><a href=\"" + href + i + "\" title=\"" + i + "\" >" + i + "</a></li>");
					}
					page.append("<li><a href=\"javascript:;\">...</a></li>");
				} else {
					int endPageIndex = pageSplit.getPageIndex() + 3 > pageSplit
							.getTotalPage() ? pageSplit.getTotalPage()
							: pageSplit.getPageIndex() + 3;

					page.append("<li><a href=\"" + href + 1 + "\" class=\"\" title=\"1\">1</a></li>");
					page.append("<li><a href=\"" + href + 2 + "\" class=\"\" title=\"2\">2</a></li>");
					page.append("<li><a href=\"javascript:;\">...</a></li>");
					for (int i = pageSplit.getPageIndex() - 3; i <= endPageIndex; i++) {
						page.append("<li");
						if (pageSplit.getPageIndex() == i) {
							page.append(" class=\" active\" ");
						} else {
							page.append(" class=\"\" ");
						}
						page.append("><a href=\"" + href + i + "\" title=\"" + i + "\" >" + i + "</a></li>");
					}
					if (pageSplit.getPageIndex() + 3 < pageSplit.getTotalPage()) {
						page.append("<li><a href=\"javascript:;\">...</a></li>");
					}
				}
			}
			page.append("<li><a href=\"" + href + pageSplit.getNextPage() + "\" title=\"下一页\">&raquo; 下一页</a></li>");
			page.append("<li><a href=\"" + href + pageSplit.getTotalPage() + "\" title=\"最后\">&raquo; 最后</a></li>");
			page.append("</ul>");
			page.append("</div>");
			output.append(page);
		}
	}

	/*
	 * (non-Javadoc)
	 * 
	 * @see javax.servlet.jsp.tagext.BodyTagSupport#doEndTag()
	 */
	@Override
	public int doEndTag() throws JspException {
		return super.doEndTag();
	}

}

第二步: 建立tld文件, 要放在WEB-IFO下面.

<?xml version="1.0" encoding="UTF-8"?>
<taglib xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-jsptaglibrary_2_0.xsd"
	version="2.0">
	
	<description>dzqOss taglibs 1.0</description>
	<display-name>dzqOss tablibs</display-name>
	<tlib-version>1.0</tlib-version>
	
	<short-name>dzqOss</short-name>
	<uri>/WEB-INF/tld/dzq_oss_taglibs.tld</uri>

	<!-- 分页  -->
	<tag>
		<name>pagination</name>
		<tag-class>com.dianziq.wenda.admin.tag.OssPageSplitTag</tag-class>
		<body-content>JSP</body-content>
		<attribute>
			<name>href</name>
			<required>true</required>
			<rtexprvalue>true</rtexprvalue>
		</attribute>
		<attribute>
			<name>data</name>
			<required>true</required>
			<rtexprvalue>false</rtexprvalue>
		</attribute>
	</tag>
	
</taglib>

第三步: JSP页面引入css, js

<!-- *************************  网站模板CSS  *********************** -->
			<link rel="stylesheet" href="<%=basePath%>bootstrap/css/bootstrap.min.css" type="text/css" media="screen" />
			<!-- *************************  网站模板JS   *********************** -->
			<script type="text/javascript" src="<%=basePath%>js/jquery-1.8.1.js"></script>
			<script type="text/javascript" src="<%=basePath%>bootstrap/js/bootstrap.min.js"></script>

第四步: 引入自定义标签

<%@ taglib prefix="dzqOss" uri="/WEB-INF/tld/dzq_oss_taglibs.tld"%>

第五步: 调用.

<dzqOss:pagination href="bgMng/user/userFlag!query.action?queryType=${queryType}&keyword=${keyword}" data="ossUserFlagSplit"></dzqOss:pagination>

注意: 其中href中,我们直接用${}表达式直接输入,会导致JS注入的,所以在Java代码中我利用了.

// 转义href
		href = StringEscapeUtils.escapeHtml4(href);
		href = StringEscapeUtils.escapeEcmaScript(href);

在Strus中, <s:property value="userName" escapeHtml="true"/> 源码里也是用的这个转义的common-lang包. 比较好用. 

看看运行效果图:
