為何我用spring mvc獲取不到表單提交資料？

SpringMVC

這個問題也困擾了我很久，自己學習用的很多專案也需要表單提交，用@ModelAttribute和@RequestParam都沒有用。。

不知道是否是配置有問題，以下是部分程式碼，使用的IDE是idea15.0，

第一次用CSDN問問題，可能格式不規範，多多包涵。

Controller：

@Controller
public class UserController {
    private static final Log logger = LogFactory.getLog(UserController.class);

    @RequestMapping(value = "/{formName}")
    public String loginForm(
            @PathVariable String formName){
        return formName;
    }

    @RequestMapping(value = "/register", method = RequestMethod.POST)
    public String login(
//            @RequestParam(value = "loginname", required = false) String loginname,  //沒用
//            @RequestParam(value = "birthday", required = false) Date birthday,  //沒用
            @ModelAttribute("user") User user,    //沒用
            Model model){
        logger.info(user);
        model.addAttribute("user", user);
        return "success";
    }
}
