I think what you're looking for is session variables in Spring. There's actually 4 ways of doing it, each with its pros and cons. You can find more details in the following link. It provides one of the best explanation on this topic on the net.

为什么不能直接在 loginProcess 中调用 dvdCURDOperation 方法。

如果您的目标是 302 重定向，以便浏览器 url 更改为

/dvd_hibernate/DvdController/dvdCURDOperation

您必须在 Session 中保存 userDeutils 并在 dvdCURDOperation 方法中检索它。

request.getSession.setAttribute("userDetails", userDetails);
return new ModelAndView("redirect:/dvd_hibernate/DvdController/dvdCURDOperation");

As you've no doubt discovered by now, passing a ModelMap to a RedirectView will have no effect. Others have mentioned session variables, but if you'd prefer to keep your controllers stateless, you can pass any arguments you need as URL parameters.
