为什么我的“重定向”（即return "redirect:/myPage"）无效？
注意：“myPage”是Tiles页面定义。
（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。）
到目前为止，我已经尝试了以下内容。
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]。
（注意：主要布局模板和构成“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。
什么可能阻止我重定向到Tiles页面定义：“myPage”？

答案 0 :(得分：5)
感谢Sotirios的评论留下的暗示，我发现我无法“重定向”到“myPage”与Tiles无关。
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。
我不得不向Controller添加以下“public ModelAndView myPage（HttpSession session）”方法（参见下面的代码片段），以便执行成功的重定向（即，从另一个控制器）...即，使用< / p>
return new ModelAndView("redirect:/myPage");
问题是“myPage”控制器不包含“公共ModelAndView myPage（HttpSession会话）”方法......（再次感谢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");
}
