controller

@PostMapping("/uploads")
    public String uploads(MultipartFile[] files, HttpServletRequest req){
        String format = sdf.format(new Date());
        String realPath = req.getServletContext().getRealPath("/img/")+ format;
        File folder = new File(realPath);
        if(!folder.exists()){
            folder.mkdirs();
        }
        for (MultipartFile file : files) {
            String oldName = file.getOriginalFilename();
            String newName = UUID.randomUUID().toString()+oldName.substring(oldName.lastIndexOf("."));
            try {
                file.transferTo(new File(folder,newName));
                String url = req.getScheme()+"://"+req.getServerName()+":"+req.getServerPort()+"/img/"+format+"/"+newName;
                System.out.println(url);
                //return "success";
