呵呵，楼主既然思路都有了还怕写不出代码么？
你这个思路没有问题的！
可以把这个问题拆分复成几个小问题，就简单多了。
第一是文件上传，可以参照Jakarta的FileUpload组件，其实也不一定要用这制个，用普通的Post也就行了。
第二是Excel解析，用JSL或者POI都行
第三是数据保存，这个应该简单吧，一个循环，一行对应一条数据，写好了方法循环赋值调百用就行了。
第四是查询和显示，这个更简单了，度不用多说。
文件上传和Excel解析的例子网上很多的，改改就变自己的了，何必在这管别人要代码呢～
private static HSSFWorkbook readFile(String filename){
zhidaotry {
wb = new HSSFWorkbook(new FileInputStream(filename));
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return wb;
}
两种jar包内 jxl 和 apache的集成开源 写入文件容或者直接保存
一、列表页面的部分代码
[html] view plaincopy
<input type="button" class="cxBut2" value="导出数据" onclick="_export()"/>
[javascript] view plaincopy
function _export(){
document.location.href="download.jsp?czId=<%=czId%>&czNum=<%=czNum%>&beginIssue=<%=beginIssue%>&endIssue=<%=endIssue%>&pageNum=<%=pageNum%>&czName="+$("#czId").find("option:selected").text();
}
二、download.jsp
[html] view plaincopy
<%@ page contentType="application/vnd.ms-excel" language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@page import="com.zhcw.kaijiang.service.ExportExcal"%>
<%@page import="java.io.OutputStream"%>
<%
String czNum = request.getParameter("czNum");
String czId = request.getParameter("czId");
String czName = request.getParameter("czName");
String beginIssue = request.getParameter("beginIssue");
String endIssue = request.getParameter("endIssue");
String pageNum = request.getParameter("pageNum");
response.resetBuffer();
response.setHeader("Content-Disposition", "attachment;filename="+ new String(czName.getBytes("UTF-8"), "iso8859-1")+".xls");//指定下载的文件名
response.setContentType("application/vnd.ms-excel");
try{
ExportExcal exportExcal = new ExportExcal(beginIssue, czId, czName, czNum, endIssue, pageNum);
exportExcal.export(response.getOutputStream());
}catch(Exception ex){
ex.printStackTrace();
}
%>
3.这个页面主要负责接收上一个页面传来的数据，e68a84e799bee5baa6e997aee7ad94335然后调用后台相应的导出方法来实现导出功能。
注意：这两行代码必须要写：
[html] view plaincopy
response.resetBuffer();<pre name="code" class="html">response.setContentType("application/vnd.ms-excel");</pre>
<pre></pre>
<p></p>
<pre></pre>
<p></p>
<p></p>
三、后台处理类<pre name="code" class="java">package com.zhcw.kaijiang.service;
