问题
Why is my "redirect" (that is, return "redirect:/myPage") not working?
Note: "myPage" is a Tiles page definition.
(FWIW, the solution to a "double-submit" issue I am having is use a redirect to "myPage". But I am unable to get the "redirect" to work.)
So far, I've tried the following.
return new ModelAndView("redirect:/myPage"))
return new ModelAndView("redirect:/myPage.jsp"))
return new ModelAndView("redirect:/views/myPage"))
return new ModelAndView("redirect:/views/myPage.jsp"))
return new ModelAndView(new RedirectView("myPage"))
return new ModelAndView(new RedirectView("myPage.jsp"))
return new ModelAndView(new RedirectView("/views/myPage"))
return new ModelAndView(new RedirectView("/views/myPage.jsp"))
return new ModelAndView(new RedirectView("/WEB-INF/views/myPage"))
return new ModelAndView(new RedirectView("/WEB-INF/views/myPage.jsp"))
But, to no avail. None of the above URLs redirects work. That is, I get HTTP Status 404 - [description, the requested resource is not available].
(Note: the main layout template, and the JSP files that comprise the "myPage" page definition are located in a "WEB-INF/views" folder.)
Below is some relevant configuration information.
What might be preventing me from redirecting to the Tiles page definition: "myPage"?

回答1:
Thanks to hints left by Sotirios' comments, I discovered that my inability to "redirect" to "myPage" had nothing whatever to do with Tiles.
Rather, after a harder look, I realized that it was the configuration of the controller associated with "myPage".
I had to add the following "public ModelAndView myPage(HttpSession session)" method to the Controller (see snippet, below), in order to perform a successful redirect (i.e., from another controller)...i.e., using
return new ModelAndView("redirect:/myPage");
The problem was that the "myPage" controller did not contain an "public ModelAndView myPage(HttpSession session)" method...(thanks again, Sotirius).
Below, is the "public ModelAndView myPage(HttpSession session)" method - code snippet)
@Controller
@Scope("session")
@SessionAttributes(
{
"sharedList"
})
public class MyPageController implements Serializable
{
@ModelAttribute("sharedList")
public List<Pojo1> createSharedList()
{
return new ArrayList<Pojo1>();
}
@RequestMapping(value = "/myPage", method = RequestMethod.GET)
@ResponseBody
public ModelAndView myPage(HttpSession session)
{
createSharedList();
return new ModelAndView("myPage");
}
