java,使用美图秀秀上传,设置头像

最近在倒弄个一个网站，www.thinkdee.com 没有完成，还在做，这里要用到用户头像设置，本来想自己处理的，看到网上美图功能太强大了，就试了一把！

美图开放平台：http://open.web.meitu.com/

开发文档：http://open.web.meitu.com/wiki/

后台图片处理：

@RequestMapping("uploadface")
    @ResponseBody
    public boolean uploadface(HttpServletRequest request,HttpServletResponse response,@RequestParam("Filedata") MultipartFile file ) throws Exception{
        if(!file.isEmpty()){
            //得原始名字1.jpg
            String originName = file.getOriginalFilename();
            //取出.jpg
            String fileType = originName.substring(originName.indexOf("."));
            //生成新文件名 abc
            String newFileName = UUIDGenerator.getUUID();
            //生成abc.jpg
            String newFile = newFileName + fileType;
            //文件生成的路径-文件夹
//            String uploadDir = MyWebUtil.getUploadHeadPath();
            
            SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMdd");
            String datePath = sdf.format(new Date());

            File f = new File(uploadDir);
            if(!f.exists()){
                f.mkdirs();
            }
            String toDiskPath    = imgPath + newFile;
            //生成的文件路径

            byte[] bytes = file.getBytes();
            FileOutputStream fos = new FileOutputStream(filePath);
            fos.write(bytes);  //写入文件
            //更新数据库
            Subject subject = SecurityUtils.getSubject();
            String logName = (String)subject.getPrincipal();

            String mid = filePath +"-mid" +fileType;

            ScaleImage is = new ScaleImage();
