springMVC <input type="file" 的簡單上傳至服務器

簡單的文件上傳 ，供大家參考

private  object uploadPDF(HttpServletRequest request, Object object ) throws IOException{

MultipartHttpServletRequest multipartRequest = (MultipartHttpServletRequest) request;
MultipartFile multipartfile = multipartRequest.getFile("pdfPath");
if (multipartfile != null && multipartfile.getSize() > 0) {
StringBuffer buffer = new StringBuffer(FileUtils.createFolder(FolderType.BOOKCITY_PDF, id));
buffer.append(FileUtils.createFileName(multipartfile.getOriginalFilename()));
File file = new File(buffer.toString());
if (!file.exists()) {
file.mkdirs();
}
       try {
multipartfile.transferTo(file);
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
       String imageName = multipartfile.getOriginalFilename();
       if(!StrUtil.isNull(imageName)){
        //expert.setPictureName(imageName.substring(0,imageName.indexOf(".")));
       }
       String bigPath = buffer.substring(buffer.indexOf(FolderType.UPLOAD));
       object .seturl("/" + bigPath);
}
return object ;
}
