本文介绍了为什么是“重定向”？ （也就是说，`return" redirect：/ myPage"`）不能用于我的Tiles页面定义？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

为什么我的重定向（即返回redirect：/ myPage）无效？

Why is my "redirect" (that is, return "redirect:/myPage") not working?

注意：myPage是 Tiles 页面定义。

Note: "myPage" is a Tiles page definition.

（FWIW，我所遇到的双重提交问题的解决方案是使用重定向到myPage。但我无法让重定向工作。）

(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.)

到目前为止，我已尝试过以下内容。

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"))

但无济于事。以上网址都不会重定向工作。也就是说，我得到HTTP状态404 - [描述，请求的资源不可用]。

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].

（注意：主要布局模板和组成的JSP文件myPage页面定义位于WEB-INF / views文件夹中。）

(Note: the main layout template, and the JSP files that comprise the "myPage" page definition are located in a "WEB-INF/views" folder.)

以下是一些相关的配置信息。

Below is some relevant configuration information.

什么可能阻止我重定向到Tiles页面定义：myPage？

What might be preventing me from redirecting to the Tiles page definition: "myPage"?

      • 推荐答案

      感谢Sotirios的评论留下的提示，我发现我无法重定向到myPage与Tiles无关。

      Thanks to hints left by Sotirios' comments, I discovered that my inability to "redirect" to "myPage" had nothing whatever to do with Tiles.

      相反，在更难看之后，我意识到这是与myPage相关联的控制器的配置。

      Rather, after a harder look, I realized that it was the configuration of the controller associated with "myPage".

      我必须将以下公共ModelAndView myPage（HttpSession会话）方法添加到Controller（请参阅下面的代码段），以便执行成功的重定向（即，从另一个控制器）...即，使用

      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");

      问题是myPage控制器不包含 public ModelAndView myPage（HttpSession session）方法......（再次感谢Sotirius）。

      The problem was that the "myPage" controller did not contain an "public ModelAndView myPage(HttpSession session)" method...(thanks again, Sotirius).

          @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");
        }
