解决办法：
CommonsMultipartFile cf= (CommonsMultipartFile)multipartFile;
DiskFileItem fi = (DiskFileItem)cf.getFileItem();
File file= fi.getStoreLocation();
if(!file.exists()){
multipartFile.transferTo(file);
}
Map<String,String> mapImage = UploadFTPFile.getFtpUpload().getUploadPathMap(file,Constants.POSTER_FLAG,multipartFile.getOriginalFilename());
//if(file.exists())file.delete();
return mapImage;
