后台使用servlet3.0的part用于上传

	
	@RequestMapping("/upload")
	@ResponseBody
	public String upload(HttpServletRequest request) throws IOException, ServletException {
		
		String dir = System.getProperty("user.dir");
		
		Part p = request.getPart("photo");
		System.out.println(p.getSubmittedFileName());
		p.write(dir+File.separator+p.getSubmittedFileName());
		
		
		return "index";
	}
