springMVC实现多文件上传

<h2>上传多个文件 实例</h2>
<form action="/workreport/uploadMultiFile.html" method="post" enctype="multipart/form-data">
<p>
选择文件:<input type="file" name="files">
<p>
选择文件:<input type="file" name="files">
<p>
选择文件:<input type="file" name="files">
<p>
<input type="submit" value="提交">
</form>

　　 // 多文件上传
@RequestMapping(value = "/uploadMultiFile")
public String uploadMultiFile(HttpServletRequest request) {

// 创建一个通用的多部分解析器
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver(request.getSession().getServletContext());
// 判断 request 是否有文件上传,即多部分请求
if (multipartResolver.isMultipart(request)) {
// 转换成多部分request
MultipartHttpServletRequest multiRequest = (MultipartHttpServletRequest) request;
// get the parameter names of the multipart files contained in this request
Iterator<String> iter = multiRequest.getFileNames();
while (iter.hasNext()) {
// 取得上传文件
List<MultipartFile> multipartFiles = multiRequest.getFiles(iter.next());
String basePath = "F:/testDir/";

multipartFile.transferTo(new File(basePath + fileName));
}
}
}
}
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return "test/success";
}

// 文件上传
@RequestMapping(value = "/uploadFile", method = RequestMethod.POST)
public String uploadFile(HttpServletRequest request) throws IOException {
