java - Spring 配置 : No mapping found for HTTP request with URI in DispatcherServlet with name 'dispatcherServlet'

Question

我认为配置文件中缺少某些内容，但我看不到。

当我在浏览器中输入 --> localhost:8080/Procura/notifications --> 我在控制台中输入这个 -->org.springframework.web.servlet.DispatcherServlet noHandlerFound警告:在名为“dispatcherServlet”的 DispatcherServlet 中找不到带有 URI [/Procura/notifications] 的 HTTP 请求的映射

Web.xml(我也试过 3.0)

<?xml version="1.0" encoding="ISO-8859-1"?>

Controller

package com.procura.controller;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class NotificationController {

    final Logger logger = LoggerFactory.getLogger(NotificationController.class);

    @RequestMapping(value = "/notifications")
    public String listAll(Model uiModel) {
        System.out.println("In method");
        logger.info("Listing notifications");
        return "notifications/list";
    }
}

我认为<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" />与@RequestMapping 注释冲突。如果您想使用带注释的请求映射将您的请求 url 映射到 Controller ，请尝试从您的 spring mvc 配置中删除 BeanNameUrlHandlerMapping
