Hi,

Here is my controller code:

@RequestMapping(method = RequestMethod.POST)

          public String create(UploadItem uploadItem, BindingResult result,

                              HttpServletRequest request, HttpServletResponse response,

                              HttpSession session) {

                    if (result.hasErrors()) {

                              for (ObjectError error : result.getAllErrors()) {

                                        System.err.println("Error: " + error.getCode() + " - "

                                                            + error.getDefaultMessage());

                              }

                              return "categories/upload-category-image";

                    }

 

 

                    // Some type of file processing...

                    logger.debug("-------------------------------------------");

                    try {

                              MultipartFile file = uploadItem.getFileData();

                              String fileName = null;

//                              InputStream inputStream = null;

                              OutputStream outputStream = null;

                              if (file.getSize() > 0) {

 

 

                                        if (file.getSize() > 100000000) {

                                    logger.debug("File Size:::" + file.getSize());

                                    return "categories/upload-category-image";

                                        }

                                        logger.debug("size::" + file.getSize());

                                logger.debug("Category Id==>" + uploadItem.getId());

 

 

                                fileName = file.getOriginalFilename();

                                        outputStream = new FileOutputStream(fileName);

                                        logger.debug("fileName:" + file.getOriginalFilename());

                                outputStream.write(file.getBytes());

 

 

                                int pos = fileName.lastIndexOf('.');

                                String ext = fileName.substring(pos+1);

                                logger.debug("==>Id:"+Integer.parseInt(uploadItem.getId()));

                                logger.debug("==>ContentType:"+ext);

                                categoryImageService.create(Integer.parseInt(uploadItem.getId()), fileName, file.getBytes(), ext);

                                        outputStream.close();

 

 

                              }

 

 

                              // ..........................................

                              session.setAttribute("uploadFile", file.getOriginalFilename());

                    } catch (Exception e) {

                              throw new RuntimeException(e);

                    }

                    return "redirect:/categories/fullList";

          }

 

where if (file.getSize() > 100000000)  means checking if the size > 10MB?

and "categoryImageService.create(Integer.parseInt(uploadItem.getId()), fileName, file.getBytes(), ext);" thrown exception when I tried to upload a 4MB jpeg file. But 9KB is fine.

Any suggestion is very well appreciated.

Thanks

Sam
