Question

我在我的应用程序中使用spring mvc，当我创建用户时我必须在标题中显示成功消息，所以我使用了这段代码

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

        return modelAndView;

但我的问题是我在浏览器网址中收到此消息。假如我使用如下所示，成功消息显示在主页的标题中，但主页中的记录消失。

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

            return modelAndView;

这是我的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" %>

<jsp:include page="../templates/header.jsp"></jsp:include>

<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>

<style>
.errorblock {

<c:if test="${not empty errorMessage}">

</c:if>

<c:if test="${not empty successMessage}">

请帮帮我

执行重定向后，不会保留该值。所以你没有在mainPage控制器中获得successMessage。

请参阅here类似问题。

您可以按照建议将值放入会话中。或者在下一个控制器中从请求中获取它，然后将其设置为modelandview。

祝你好运。

重定向时，浏览器URL中会显示成功标题消息
