你什麼時候得到這個異常？ – VPK

服務器啓動時 –

在加載您嘗試使用它的頁面之前，您需要添加'modelAttribute'作爲模型的一個屬性。 – VPK

您需要添加屬性在控制器類用戶。

@Controller 
@RequestMapping(value = "/register") 
public class RegisterController { 
    @RequestMapping(method = RequestMethod.POST) 
    public String processRegistration(@ModelAttribute User user,Model m) {   
    User user=new User(); 
    m.addAttribute(user); 
    return "RegistrationSuccess"; 
}
