REST fileupload in Spring controller using multipart/form-data

Is it possible to upload file with additional data (like description etc.) with use of multipart/form-data? I'm using backbone.js in my frontend and I call REST api with it (jQuery).I don't use any view resolver but I want to somehow pass my file to controller like:

@RequestMapping(value = "/image/upload", method = RequestMethod.POST)public String upload(UploadItem uploadItem, HttpSession session)

so that uploadItem stores:

private String desctiption;private List<CommonsMultipartFile> fileData;

But I'm not adding (and I can't) this to my model.

Of course I'm also interested if it's possible to have controller like:

@RequestMapping(value = "/image/upload", method = RequestMethod.POST)public String upload(someFileType uploadItem, String desctiption)
