java - 即使定义了请求映射，为什么请求调度程序仍在 spring mvc 中查找 View ？

Question

我有一个spring mvc应用程序，配置如下。我已经正确配置了 spring 上下文、调度程序 servlet 和注释处理。我仍然遇到这个问题，即使我定义了请求映射，spring 仍在尝试查找 JSP，并且出现以下错误

HTTP Status 404 - /resp/WEB-INF/views/public_html.jsp

但是，我能够成功调用其他请求映射(主要是 POST)。请参阅下面的配置信息。欢迎所有建议。

Controller

@Controller
public class LandingPageController {


@RequestMapping(value = "/" , method = RequestMethod.GET)
public ModelAndView homePage(HttpServletRequest request) {

    return new ModelAndView("index", "model", null);
}

@RequestMapping(value = "/public_html", method = RequestMethod.GET)
public ModelAndView homePagePub(HttpServletRequest request) {

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

提前致谢!

让我们复兴这个......:)

这应该有效......但无论如何你还有其他选择可以尝试。 您可以返回一个 RedirectView，或者只是返回一个 String 'redirect:/'。

//...
@RequestMapping(value = "/public_html", method = RequestMethod.GET)
public View homePagePub() {
    return new RedirectView("/", true);
}
// - OR -
@RequestMapping(value = "/public_html", method = RequestMethod.GET)
public String homePagePub() {
    return "redirect:/";
}
//...
