Spring配置：在DispatcherServlet中找不到带有URI的HTTP请求的映射，名称为“dispatcherServlet”

Question

我认为配置文件中缺少某些内容，但我看不到。

当我放入浏览器时 - ＆gt; localhost：8080 / Procura / notifications - ＆gt;我进入控制台了 - ＆gt; org.springframework.web.servlet.DispatcherServlet noHandlerFound Warnung：在DispatcherServlet中找不到带有URI [/ Procura / notifications]的HTTP请求的映射，名称为“dispatcherServlet”

Web.xml（我也试过3.0）

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<servlet-mapping>

</servlet-mapping>

</web-app>

控制器

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";
    }
}

项目结构

Answer 1

我认为<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" />与@RequestMapping注释相冲突。 如果要使用带注释的请求映射将请求URL映射到控制器，请尝试从spring mvc config中删除B​​eanNameUrlHandlerMapping

Answer 2

显然Tomcat已损坏。但现在一切正常。

Answer 3

第一个甚至让dispatcherServlet阻塞后缀如：* .do; 这样jsp后缀就不会被阻塞，第二种方法是添加spring-servlet.xml MVC：默认servlet的处理程序
