Question

I am using spring mvc in my application,when i created user i have to show the success message in a header,
so i used this code

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

        return modelAndView;

But my problem is i am getting this message in browser url. suppose if i use like as below,Success message is showing in a header of mainpage ,but the records in main page disappear.

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

            return modelAndView;

this is my 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" %>

Answer 1

Once you do a redirect the value is not preserved. So you are not getting successMessage in the mainPage controller.

See here a similar question.

You can put the value in session as suggested.
Or in the next controller fetch it from the request and then set it to the modelandview.

Best of luck.
