Question

我收到此404错误消息

The requested resource (/ghs1986/WEB-INF/pages/poll1.jsp) is not available.

来自这种控制器方法。

@RequestMapping(value = "/poll1", method = RequestMethod.POST)
public ModelAndView processPoll1(@RequestParam String vote) {
    poll1DAO.tallyVote(vote);
    ModelAndView modelAndView = new ModelAndView("PollPage");
    modelAndView.addObject("PollPage", new Cookie("poll1", "voted"));
    return modelAndView;    
}

这是ghs1986-servlet.xml

Answer 1

问题解决了。我更改了方法以返回String并返回以下内容：

return "redirect:/polls";

使用ModelAndView的Spring 3 - 404错误
