java - 可以将redirectView 与jsp 一起使用吗？

Question

我需要在重定向后显示一条“消息”，modelAndView但是众所周知，这是不可能的，然后，我使用redirectView，但我不知道如何显示视图。总之，我需要改变这个：

ModelAndView model = new ModelAndView("product/edit");

在

RedirectView redirectView = new RedirectView("product/edit");

Answer 1

You can store message as session scope attribute and then redirect to jsp page where you can access it back using JSP Standard Tag Library and Expression language.

Controller:

@RequestMapping(...)
public String method1(...){
    ...
    session.setAttribute("message", "Hello, How are you?");
    return "redirect:product/edit";
}

Note: Here you can use RedirectView as well.

JSP:

${sessionScope.message}
