form表单文件上传后台处理

fileUpload接收到form提交请求,DefaultMultipartHttpServletRequest类封装了form提交的所有信息，包括文件上传信息

@RequestMapping(name="/fileUpload",method=RequestMethod.POST)

public String upload(DefaultMultipartHttpServletRequest request,HttpServletResponse response){

try {

MultipartFile multipartFiles = request.getFile("orgKey");

multipartFiles.transferTo(new File( "d:/log/3"+multipartFiles.getOriginalFilename()));

MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;

Map<String, MultipartFile>  map= multipartRequest.getFileMap();

Set<Map.Entry<String, MultipartFile>>  set = map.entrySet();

for(Map.Entry<String, MultipartFile> entry :set){

MultipartFile multipartFile =entry.getValue();

String fileName = multipartFile.getOriginalFilename();

InputStream inputStream = multipartFile.getInputStream();

String localName = "d:/log/"+multipartFile.getOriginalFilename();

File  localFile =new File(localName);

        FileUtils.copyInputStreamToFile(inputStream, localFile);

}

} catch (Exception e) {

e.printStackTrace();

}

return null;

}
