我正在開發一個應用程序,其中當用戶按下「登錄」按鈕LoginForm.jsp
和UserRegistration.jsp
會導致UserAccount jsp
網頁上的特定action.In LoginForm
- >用戶帳戶表單顯示。在用戶註冊表單中輸入詳細信息並提交時 - 顯示用戶帳戶表單。 下面是控制器代碼,當請求爲UserAccount.html
如何知道從哪個jsp頁面請求已經到控制器中的Spring MVC
@RequestMapping(value="/UserAccount.html", method = RequestMethod.POST)
public ModelAndView userAccountForm(@Valid @ModelAttribute("user") UserDetails user,BindingResult result) {
if(result.hasErrors())
{ System.out.println(result.getAllErrors());
ModelAndView model1=new ModelAndView("UserRegistration");
return model1;
}
// User validation
System.out.println(user.getAccountType());
userDAO.create(user);
ModelAndView model1 = new ModelAndView("UserAccount");
return model1;
}
loginForm.jsp中
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>

現在對我來說,我需要知道從jsp頁面UserAccount被調用,基於此執行不同的操作。 我是Spring MVC的新手,並在整個互聯網上搜索解決方案。
第一個沒有工作一些how.it返回空值 –
您是否在窗體中爲頁面參數添加了隱藏字段? – stevecross
是的我已經在我的兩個頁面中添加了LoginForm和UserRegistration,如下所示:和 –
