Spring mvc 图片上传,求代码

Spring mvc 图片上传，public void savePhoto(InputStream inputStream) throws Exception 里面怎么写

@RequestMapping("saveAdvertFile.action")
public ModelAndView saveAdvertFile(@RequestParam MultipartFile loadPicPath, HttpServletRequest request)
{
if (loadPicPath != null)
{
log.info("file name=" + loadPicPath.getOriginalFilename());

                    //保存图片路径
        String realPath = CConstants.ADV_ROOT_PATH
            + System.currentTimeMillis() + loadPicPath.getOriginalFilename();
        try
        {File newFile = new File(realPath);
            loadPicPath.transferTo(newFile);

            status.setFilePath(realPath);
            status.setLoadSuccess(true);

        }
        catch (Exception e)
        {
            log.error("error file load:" + e);

            status.setFilePath("");
            status.setLoadSuccess(false);
        }

    }
    else
    {
        log.info("file name=null.");
    }
    return forward("/view/schedule/advert-notify", null);
}
