Question

我正在尝试学习Spring MVC。到目前为止，我已经完成了以下工作：

的web.xml

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xmlns="http://java.sun.com/xml/ns/javaee" 
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
                        http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
                        id="WebApp_ID" version="2.5">
      <display-name>SpringMvc</display-name>


      <servlet>
          <servlet-name>spring</servlet-name>
          <servlet-class>
             org.springframework.web.servlet.DispatcherServlet
          </servlet-class>
          <load-on-startup>1</load-on-startup>
       </servlet>

      <servlet-mapping>
        <servlet-name>spring</servlet-name>
        <url-pattern>/</url-pattern>
      </servlet-mapping>

    </web-app>

弹簧servlet.xml中

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/mvc
                        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
                        http://www.springframework.org/schema/beans
                        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <mvc:resources location="/resources/" mapping="/resources/**"/> 
    <mvc:annotation-driven/>
    <context:component-scan base-package="com.awesomememe"></context:component-scan>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>


</beans>

HomeController.java

package com.awesomeme.controllers;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;

@Controller
public class HomeController {

    public String showHomePage(Model model){
        model.addAttribute("message","Smrita is awesome");
        return "home";
    }

}

针对home.jsp

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Home Page</title>
</head>
<body>
        Message from the controller is 
        <h1>${message}</h1>
</body>
</html>

我的目录结构如下：

我添加了以下罐子：

但是当我尝试运行应用程序时，我收到以下错误：

我到底错过了什么。任何建议都会有很大的帮助。

为什么我得到java.lang.ClassNotFoundException：org.springframework.web.servlet.DispatcherServlet错误？
