为什么“重定向”(即,“返回“ redirect:/ myPage””返回)不适用于我的Tiles页面定义?

jsp

为什么我的“重定向”(即return "redirect:/myPage")不起作用?

注意:“
myPage”是Tiles页面定义。

(FWIW,我遇到的“双提交”问题的解决方案是使用重定向到“ myPage”。但是,我无法使“重定向”正常工作。)

到目前为止,我已经尝试了以下方法。

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"))

但是,无济于事。以上所有URL均无法重定向。即,我得到HTTP状态404-[描述,请求的资源不可用]。

(注意:主布局模板和组成“ myPage”页面定义的JSP文件位于“ WEB-INF / views”文件夹中。)

以下是一些相关的配置信息。

是什么导致我无法重定向到Tiles页面定义:“ myPage”?

感谢Sotirios的评论所留下的提示,我发现无法“重定向”到“ myPage”与Tiles没有任何关系。

相反,经过一番努力,我意识到这是与“ myPage”关联的控制器的配置。

我必须将以下“ public ModelAndViewmyPage(HttpSession会话)”方法添加到Controller中(请参见下面的代码段),以便执行成功的重定向(即从另一个控制器进行重定向)…即,使用

return new ModelAndView("redirect:/myPage");

问题是“ myPage”控制器 包含“公共ModelAndView
myPage(HttpSession会话)”方法…(再次感谢,Sotirius)。

下面是“公共ModelAndView myPage(HttpSession会话)”方法-代码段)

    @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");
        }
