You should use Redirect Flash Model attributes when redirecting.

 @RequestMapping(value = "/add", method = RequestMethod.POST)
      public ModelAndView adduser(@ModelAttribute("productForm") Errors error, RedirectAttributes redir) {

        ModelAndView modelAndView = new ModelAndView("product");
        System.out.println(modelAndView);
        redir.addFlashAttribute("outMessage", "User Registration Success");
        return new ModelAndView("redirect:/productSetup");
      }

Refer this for more info : https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/web/servlet/mvc/support/RedirectAttributes.html
