POI读取Excel2003数据存储数据库
1、JSP Form表单部分代码（关键：enctype="multipart/form-data"）
<FORM id=impform name=impform action="ImportOperation1.jsp"
method=post enctype="multipart/form-data" onSubmit="onSave();return false">
<TABLE class=viewform width="100%">
<COLGROUP>
<COL width="20%">
<COL width="80%">
<TBODY>
<TR class=Title>
<TH colSpan=2><%=SystemEnv.getHtmlLabelName(19464,user.getLanguage())%></TH></TR>
<TR class=spacing>
<TD class=line1 colSpan=2 ></TD></TR>
<TR class= Spacing><TD class=Line colSpan=2></TD></TR>
<TR>
<TD><%=SystemEnv.getHtmlLabelName(16699,user.getLanguage())%></TD>
<TD class=Field>
<input class=inputstyle type=file name="filename" size=40>
<button Class=AddDoc type=button onclick="onSave(this)">
<%=SystemEnv.getHtmlLabelName(18596,user.getLanguage())%></button> </TD>
</TR>
<TR class= Spacing><TD class=Line colSpan=2></TD></TR>
<%
String msg="";
if(request.getAttribute("msg")!=null){
msg = Util.null2String((String)request.getAttribute("msg"));
}
if(msg!=""){
%>
<TR>
<td id="msg" align="left" colspan="3">
<font size="2" color="#FF0000"><%=msg %></font>
</td>
</TR>
<%} %>
<TR>
<td><a href="markerInformation1.xls"><%=SystemEnv.getHtmlLabelName(18616,user.getLanguage())%></a></td>
</TR>
<TR>
<td align="left" colspan="3">
说明：请按模板排列导入EXCEL文档中各字段的顺序 </td>
</TR>
<TR class= Spacing><TD class=Line1 colSpan=2></TD></TR>
</TBODY>
</TABLE>
<div id='_xTableLoadmask' style='background:#FFFFFF;padding:3px;width:100%;display:none' valign='top'></div>
</FORM>
2、接收请求ImportOperation1.jsp
<%@page import="weaver.file.FileUploadToPath"%>
<%@ page import="weaver.general.Util" %>
<%@ page import="java.util.*" %>
<%@ page language="java" contentType="text/html; charset=GBK" %> <%@ include file="/systeminfo/init.jsp" %>
<jsp:useBean id="rs" class="weaver.conn.RecordSet" scope="page" />
<%@ page import="westvalley.basis.Markerinformation"%>
<%
//文件上传
FileUploadToPath fu = new FileUploadToPath(request) ;
//上传后的文件路径
filename = fu.uploadFiles("filename");
Markerinformation mi = new Markerinformation(request,response);
mi.import1Data(filename,request);
//进行导入
System.err.println("信息"+mi.getMsg());
request.setAttribute("msg", mi.getMsg());
request.getRequestDispatcher("import1.jsp").forward(request, response);
%>
