java - PageNotFound - 在 DispatcherServlet 中未找到带有 URI [] 且名称为 'dispatcher' 的 HTTP 请求的映射

Question

在我的 Spring MVC 应用程序中，除了一个之外，我的所有 RequestMapping 都已正确映射。我无法弄清楚为什么会出现 PageNotFound 错误。对于方法 addSatisfaction，我收到 PageNotFound - 在名为“dispatcher”的 DispatcherServlet 中未找到带有 URI [/CCHPWeb/heart2heart/feedback/102/resolution/satisfaction] 的 HTTP 请求的映射.

我的 Controller :

@Controller
@RequestMapping("/heart2heart/feedback")
public class H2HFeedbackController {

    private static final Logger logger = LoggerFactory.getLogger(H2HFeedbackController.class);
    private final ActivitiService activitiService;
    private final Heart2HeartService heart2heartService;

    @Autowired
    public H2HFeedbackController(ActivitiService activitiService, Heart2HeartService heart2heartService) {
    super();
    this.activitiService = activitiService;
    this.heart2heartService = heart2heartService;
    }

    @RequestMapping(value = "/${feedbackId}/resolution/satisfaction", method = RequestMethod.GET)
    public String getSatisfaction(@PathVariable int feedbackId, Model model) {
    Feedback feedback = new Feedback();
    feedback.setId(feedbackId);
    try {
        feedback = heart2heartService.getFeedbackById(feedback);
        if (feedback.getId() == 0) {
        model.addAttribute("error", "Feedback does not exist");
        model.addAttribute("status", "404 - Not Found");
        return "error";
        }
        model.addAttribute("feedback", feedback);
    } catch (Exception e) {
        logger.error("Exception :: ", e);
    }
    return "heart2heart/closeFeedback";
    }

    @RequestMapping(value = "/{feedbackId}", method = RequestMethod.GET)
    public String viewFeedback(@PathVariable int feedbackId, Model model) {
    Feedback feedback = new Feedback();
    feedback.setId(feedbackId);
    try {
        feedback = heart2heartService.getFeedbackById(feedback);
        if (feedback.getId() == 0) {
        model.addAttribute("error", "Feedback does not exist");
        model.addAttribute("status", "404 - Not Found");
        return "error";
        }
        model.addAttribute("feedback", feedback);
    } catch (Exception e) {
        logger.error("Exception :: ", e);
    }
    return "heart2heart/feedbackView";
    }
}

我的WebApplicationInitializer是:

public class SiteMain implements WebApplicationInitializer {
    @Override
    public void onStartup(ServletContext container) throws ServletException {
        AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext();
        dispatcherContext.register(MvcConfig.class);
        ServletRegistration.Dynamic dispatcher = container.addServlet("dispatcher", new DispatcherServlet(dispatcherContext));
        dispatcher.setLoadOnStartup(1);
        dispatcher.addMapping("/");
    }
}

Answer 1

这里不需要 $:

/${feedbackId}/resolution/satisfaction

更改为

/{feedbackId}/resolution/satisfaction

$ 代表正则表达式中的“字符串(或行)结尾”。我认为您在路径映射中并不真正需要它，因为它对于整数 FeedbackId 没有意义。
