无法将文件保存在控制器中的磁盘上

Question

I have following controller:

@PostMapping(value = "/load_attachment")
    public DeferredResult uploadingPost(@RequestParam("attachment") MultipartFile[] uploadingFiles, @RequestParam("stoneId") String stoneId) throws IOException {
        logger.info("Upload {} files for stone: {}", uploadingFiles.length, stoneId);
        for (MultipartFile uploadedFile : uploadingFiles) {
            File file = new File(uploadedFile.getOriginalFilename());
            uploadedFile .transferTo(file);
            logger.info("path:{}", file.getAbsolutePath()); // I expect to find files here

        }
}

No exceptions happens but I could not find files on file system.

In your case, Application server doesn't application server inside folder path so you should specify it manually!...

  for (MultipartFile uploadedFile : uploadingFiles) {
        File file = new File("path/to/your/server/application/directory"+uploadedFil‌e.getOriginalFilenam‌e());
        uploadedFile .transferTo(file);
        logger.info("path:{}", file.getAbsolutePath()); // I expect to find files here

    }
