本文实例讲述了JSP导出Excel文件的方法。分享给大家供大家参考,具体如下:

<%@page import=\"jxl.Workbook,com.ecc.emp.core.*,com.ecc.emp.data.*,com.ecc.emp.jdbc.ConnectionManager,jxl.format.VerticalAlignment,java.sql.*,jxl.write.*,jxl.format.UnderlineStyle,javax.sql.DataSource\"%>
<%@page language=\"java\" contentType=\"text/html; charset=UTF-8\"%>
<%@taglib uri=\"/WEB-INF/CTP.tld\" prefix=\"ctp\"%>


<%@ include file=\"http://www.xxxx.com/head.jsp\" %>
<%
 Context context = (Context)request.getAttribute(\"context\");String flag =\"交易日期,交易时间,摘要,借方发生额,贷方发生额,对方账号,对方户名,单位卡号,主卡标识,用途,备注\";
 IndexedCollection indexedCollection = (IndexedCollection)context.getDataElement(\"parentCardDetails\");
 String[] sourceStrArray=flag.split(\",\");
 List selValList = new ArrayList();
 selValList.add(\"序号#\");
 for(int i=0;i
 
 <%
