　　采用fileupload组件进行上传，jsp页面：

<form name="upform" method="post" action="${basePath}data/upload" enctype="multipart/form-data">

<tr>
<th colspan="2" align="center">

<input id="email" name="email" type="text" value="${item.email}">
</td>
</tr>

</td>
</tr>
</table>
<center>
<input  type="submit" value="提交">
<input  type="reset" value="重置">
</center>
</form>
　　对应的控制层的代码：

protected String storeFile(HttpServletRequest request, String baseDir)
throws Exception {
DiskFileItemFactory factory = new DiskFileItemFactory();
ServletFileUpload upload = new ServletFileUpload(factory);
List<FileItem> items = upload.parseRequest(request);
Iterator<FileItem> itr = items.iterator();
String file = "common_data_file_";
while (itr.hasNext()) {
FileItem item = (FileItem) itr.next();
if (!item.isFormField()) {
System.out.println("上传文件的大小:" + item.getSize());
System.out.println("上传文件的类型:" + item.getContentType());
System.out.println("上传文件的名称:" + item.getName());
file = file + item.getFieldName();
item.write(new File(baseDir + File.separator + file));
break;
}
}
return file;
}
