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 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
}
}
