spring 3 upload many files

Question

yeah,our customer want to upload more than one file. we use spring 3 mvc. the official example like this:

markup:

<form method="post" action="/form" enctype="multipart/form-data">
  <input type="text" name="name"/>
  <input type="file" name="file"/>
  <input type="submit"/>
</form>

code:

@RequestMapping(value = "/form", method = RequestMethod.POST)
public String handleFormUpload(@RequestParam("name") String name,
                               @RequestParam("file") MultipartFile file) {

  if (!file.isEmpty()) {
    byte[] bytes = file.getBytes();
    // store the bytes somewhere
    return "redirect:uploadSuccess";
  } else {
    return "redirect:uploadFailure";
  }
}

there is only one file,so i can write the file input name in the method. but what should i do if i want to upload many files. i could not write all the file input names because if is generated by the js code. i only know that its name like 'attach_' then ,what should i write in the method ? if i write like this

 @RequestParam() MultipartFile file

or

@RequestParam("attach_") MultipartFile file

i'll get a error.
