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