成功標題消息是顯示在瀏覽器的URL重定向

Question

當我在使用Spring MVC在我的應用程序，當我創建的用戶我必須表明在頭成功消息， 所以我用這個代碼

modelAndView.setViewName("redirect:/mainPage"); 
     modelAndView.addObject("successMessage", "user created successfully"); 

     return modelAndView; 

但我的問題是我在瀏覽器URL中收到此消息。假設如果我使用像下面那樣，Success消息顯示在主頁面的標題中，但主頁面中的記錄消失。

modelAndView.setViewName("mainPage"); 
      modelAndView.addObject("successMessage", "user created successfully"); 

      return modelAndView; 

這是我mainpage.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1" 
    pageEncoding="ISO-8859-1"%> 
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> 
<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %> 
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>

<script type="text/javascript" src="js/bootstrap-dropdown.js"></script> 
<script type="text/javascript"> 
// Implement checkbox-like buttons 
$(".toggle-buttons > .g-button").click(function() { 
    $(this).siblings(".g-button").removeClass("checked"); 
    $(this).addClass("checked"); 
}); 
</script>

請幫我提前

Answer 1

感謝一旦你做了重定向不保留的價值。所以你沒有在mainPage控制器中獲得successMessage。

請參閱here一個類似的問題。

您可以按照建議將該值放入會話中。 或者在下一個控制器從請求中獲取它，然後將其設置爲modelandview。

祝你好運。
