自定义标签分页.doc

下面是使用自定义标签分页的方法 首先是tld文件(fenYeTag.tld)： ?xml version=1.0 encoding=UTF-8? !DOCTYPE taglib PUBLIC -//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN /dtd/web-jsptaglibrary_1_2.dtd taglib tlib-version2.0/tlib-version jsp-version1.0/jsp-version short-namefenyeTag/short-name tag namefenYeTag/name tag-classorg.itstar.olineExam.usersManage.util.FenYeTagelib/tag-class !-- 所要跳转的action -- attribute nameaction/name requiredtrue/required rtexprvaluetrue/rtexprvalue /attribute !-- 总记录数 -- attribute nameallCount/name requiredtrue/required rtexprvaluetrue/rtexprvalue /attribute !-- 当前的页数 -- attribute namecurrentPageIndex/name requiredtrue/required rtexprvaluetrue/rtexprvalue /attribute !-- 每一页所要显示的条数 -- attribute namejishu/name requiredtrue/required rtexprvaluetrue/rtexprvalue /attribute !-- 所要调用的方法 -- attribute namemethod/name requiredfalse/required rtexprvaluetrue/rtexprvalue /attribute /tag /taglib 接下来是标签体FenYeTagelib.java package org.itstar.olineExam.usersManage.util; import javax.servlet.ServletRequest; import javax.servlet.jsp.JspException; import javax.servlet.jsp.tagext.BodyContent; import javax.servlet.jsp.tagext.BodyTagSupport; /** * @author 龚世俊 E-mail:gongshijun2005@126.com * @version 创建时间：2008-8-11 下午12:07:28 * 类说明，用于分页 */ public class FenYeTagelib extends BodyTagSupport { //用户请求的method private String method; //点击时提交处理的url(必须) private String action; //数据库的数据总条数(必须) private int allCount = 0; //显示给用户看的内容 private String outer=; //当前页号(必须) private int currentPageIndex = 1; //每页显示的条数(必须) private int jishu = 0; //总页数 private int pageCount = 0; /** * 根据总记录数和每页的基数计算总页数 */ public void countPageCount() { int temp = this.allCount%this.jishu; if(temp!=0) { this.pageCount = allCount/this.jishu+1; } else { this.pageCount = allCount/this.jishu; } } public void setBodyContent(BodyContent arg0) { super.setBodyContent(arg0); }
