下面分享一下个人对这个问题的解决办法，同时也请有更好解决方法的高手不吝指教！

首先是controller层：（这是点击页面“注册”按钮，表单提交的action）

// 保存到数据库	@RequestMapping(value = "doRegister", method = RequestMethod.POST)	public RedirectView createUser(@ModelAttribute("user") User user, RedirectAttributes redirectAttributes,			HttpServletResponse response) {		// 模拟数据库保存		System.out.println(user.getUsername() + "   is saved!");		redirectAttributes.addAttribute("username", user.getUsername());		return new RedirectView("{username}");	}    // 注册成功后展现用户主页    @RequestMapping(value = "{username}", method = RequestMethod.GET)    public String showUserHome(@PathVariable String username, Model model, HttpServletRequest request) {             model.addAttribute(username);        return request.getAttribute(Keys.SKIN_DIR_NAME) + "home";    }

其次是拦截器：（加入一些全局配置，如基本的站点信息）

@Override	public void postHandle(HttpServletRequest request, HttpServletResponse response, Object arg2,			ModelAndView modelAndView) throws Exception {		final Map<String, Object> model = modelAndView.getModel();		if (!(modelAndView.getView() instanceof RedirectView)) {			model.put("param1", "value1");			model.put("param2", "value2");			model.put("param3", "value3");		} else {			//进行其它操作		}	}

关键点是org.springframework.web.servlet.view.RedirectView。
