java利用MultipartRequest的getFileName方法不能得到原文件名问题

想利用MultipartRequest的getFileName方法来一次获取多个上传的文件名字时,得到的不是文件的名字,而是 input 的name属性

最后找到了答案，解决方法，参照http://stackoverflow.com/questions/13946859/retrieve-the-file-name-while-using-file-type-input

原来的代码

   @RequestMapping(value = {"multipleFileUpload"}, method =  {RequestMethod.GET, RequestMethod.POST})

    public  String multipleFileUpload(

            ModelMap modelMap,

            MultipartHttpServletRequest request,

            HttpServletResponse response) throws IOException {

        Iterator<String> itr =  request.getFileNames();

        while(itr.hasNext()){

            String str = itr.next();    //这个文件并不是原来的文件名

            multipartFile = (CommonsMultipartFile)request.getFile(str);

            MultipartFile mpf = request.getFile(str);

            InputStream is = mpf.getInputStream();

            byte[] bytes = IOUtils.toByteArray(is);

            CompressWorker worker = new CompressWorker(statusMap, bytes, str, compressSize, jobId);

            worker.start();

        }

        modelMap.addAttribute("json", new ReturnMap("线程已经启动"));

        return "json";

    }

修改后的代码

   @RequestMapping(value = {"multipleFileUpload"}, method =  {RequestMethod.GET, RequestMethod.POST})

    public  String multipleFileUpload(

            ModelMap modelMap,

            MultipartHttpServletRequest request,

            HttpServletResponse response) throws IOException {

        CommonsMultipartFile multipartFile = null；

        Iterator<String> itr =  request.getFileNames();

        while(itr.hasNext()){

            String str = itr.next();

            multipartFile = (CommonsMultipartFile)request.getFile(str);

            String fileName = multipartFile.getOriginalFilename();   //原文件名

            MultipartFile mpf = request.getFile(str);

            InputStream is = mpf.getInputStream();

            byte[] bytes = IOUtils.toByteArray(is);

            CompressWorker worker = new CompressWorker(statusMap, bytes, fileName, compressSize, jobId);

            worker.start();

        }

        modelMap.addAttribute("json", new ReturnMap("线程已经启动"));

        return "json";

    }
