/*单个文件上传Service代码片段 需要注意的是，后台controller接收的参数不能与对象的属性名同名，不然就会数据绑定错误，如果文件也是属于该对象中的属性，也不可以，因为这个file必须要用multipartFile对象进行接收，如果是多个multipartFile就使用多个对象进行接收参数*/
    @Override
        public void addShop(Shops shop, MultipartFile photo, MultipartFile licensePhoto) throws IOException{
    
                /*进行shop的持久化*/
                shop.setApplyTime(DateUtil.format(new Date()));
                shop.setShopStatus(0);
    
                if(!photo.isEmpty() && photo.getSize()>0 && !licensePhoto.isEmpty() && licensePhoto.getSize()>0){
    
                    String sepa = File.separator;
                    //通过springMVC获取session对象
                    ServletContext session = SysContent.getSession().getServletContext();
                    System.out.println(session);
                    //项目根路径
                    String realPath = SysContent.getSession().getServletContext().getRealPath("/static/upload");
                    System.out.println(realPath);
                    //得到上传时的文件名
