	 * @param request
	 * @param response
	 * @param pageContext
	 * @return

	 */

		//获得form
		UserinfoForm myForm = (UserinfoForm) form;
		//获得提交的文件对象
		FormFile ff = myForm.getPhotos();
		//获得文件字节流
		byte[] b=ff.getFileData();
		//获得上传的文件名
		String fileName=ff.getFileName();
		//获得upload文件夹的真实路径
		String filePath=request.getSession().getServletContext().getRealPath("/images/photos");
		//获得随机的文件名
		String randomName=UUID.randomUUID().toString();
		//获得上传文件的后缀名
		String fix=fileName.substring(fileName.lastIndexOf("."));
		//创建输出文件的输出流
		FileOutputStream fos=new FileOutputStream(filePath + "/" + randomName + fix);

		//关闭
		fos.close();
		
		try {
