apache common之文件上传
依赖jar：<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.3.1</version>
</dependency>
采用fileupload组件进行上传，jsp页面：
<form name="upform" method="post" action="${basePath}data/upload" enctype="multipart/form-data">
<table class="table table-striped">
<tr>
<th colspan="2" align="center">
领客网linkrmb.com数据上传单
</th>
</tr>
<tr>
<td>
用户账户(email)：
</td>
<td>
<input id="email" name="email" type="text" value="${item.email}">
</td>
</tr>
<tr>
<td>
上传文件：
</td>
<td>
<input name="file" type="file" size="20" >
</td>
</tr>
</table>
<center>
<inputtype="submit" value="提交">
<inputtype="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;
}
