Question

我正在开发一个spring mvc项目。我想上传图片并将其保存到resources / img /文件夹。

我尝试了下面的代码，但它没有将图像保存到目录中。

@Autowired
    private HttpServletRequest request;
    try {
            // MultipartFile file = uploadItem.getFileData();
            String fileName = null;
            InputStream inputStream = null;
            OutputStream outputStream = null;
            if (multipartFile.getSize() > 0) {
                inputStream = multipartFile.getInputStream();

                System.out.println("File Size:::" + multipartFile.getSize());

                fileName = request.getSession().getServletContext().getRealPath("/resources/") + "/students/"
                        + multipartFile.getOriginalFilename();
                outputStream = new FileOutputStream(fileName);
                System.out.println("OriginalFilename:" + multipartFile.getOriginalFilename());
                System.out.println("fileName----"+fileName);
                int readBytes = 0;
                byte[] buffer = new byte[10000];
                while ((readBytes = inputStream.read(buffer, 0, 10000)) != -1) {
                    outputStream.write(buffer, 0, readBytes);
                }
                outputStream.close();
                inputStream.close();
            }

        } catch (Exception e) {
            e.printStackTrace();
        }

异常

   String saveDirectory=request.getSession().getServletContext().getRealPath("/")+"images\\";//to save to images folder
   String fileName = multipartFile.getOriginalFilename();//getting file name
   System.out.println("directory with file name: " + saveDirectory+fileName);
   multipartFile.transferTo(new File(saveDirectory + fileName));
