        String filePath = "D:/image/";

        try{
            this.uploadFile(file.getBytes(), filePath, fileName);
        } catch (Exception e) {
        }
        return "success";
    }

    public static void uploadFile(byte[] file, String filePath, String fileName) throws Exception{
        File targetFile = new File(filePath);
        if(!targetFile.exists()){
            targetFile.mkdirs();
        }
        FileOutputStream out = new FileOutputStream(filePath+fileName);
        out.write(file);
        out.flush();
        out.close();
