跟老师的一样，找不到DispatcherServlet，一直报404，为什么？

Question

我用的tomcat，服务器一启动就会报：

严重: Servlet [mvc-dispatcher] in web application [/spring-mvc-study] threw load() exception

为什么找不到DispatcherServlet啊？？

我web.xml文件如下：

<!DOCTYPE web-app PUBLIC

 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"

 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>

  <display-name>Archetype Created Web Application</display-name>

  <!-- DispatcherServlet, Spring MVC的核心 -->

  <servlet>

<servlet-name>mvc-dispatcher</servlet-name>

<servlet-class> org.springframework.web.servlet.DispatcherServlet</servlet-class>

<!-- DispatcherServlet对应的上下文配置， 默认为/WEB-INF/$servlet-name$-servlet.xml

-->

<init-param>

          <param-name>contextConfigLocation</param-name>

          <param-value>/WEB-INF/configs/spring/mvc-dispatcher-servlet.xml</param-value>

        </init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>mvc-dispatcher</servlet-name>

   <!-- mvc-dispatcher拦截所有的请求-->

<url-pattern>/</url-pattern>

</servlet-mapping>

  

  

  

</web-app>

我mvc-dispatcher-servlet.xml内容如下：

<?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:context="http://www.springframework.org/schema/context"

        http://www.springframework.org/schema/mvc

        http://www.springframework.org/schema/mvc/spring-mvc.xsd ">

<!-- 本配置文件是工名为mvc-dispatcher的DispatcherServlet使用， 提供其相关的Spring MVC配置 -->

<!-- 启用Spring基于annotation的DI, 使用户可以在Spring MVC中使用Spring的强大功能。

<context:annotation-config />

<!-- DispatcherServlet上下文， 只管理@Controller类型的bean， 忽略其他型的bean, 如@Service -->

<context:component-scan base-package="com.imooc.mvcdemo">

<context:include-filter type="annotation"

expression="org.springframework.stereotype.Controller" />

</context:component-scan>

<!-- HandlerMapping, 无需配置， Spring MVC可以默认启动。 DefaultAnnotationHandlerMapping 

annotation-driven HandlerMapping -->

<!-- 扩充了注解驱动，可以将请求参数绑定到控制器参数 -->

<mvc:annotation-driven />

<bean

class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />

<property name="prefix" value="/WEB-INF/jsps/" />

<property name="suffix" value=".jsp" />

</bean>

</beans>

访问http://localhost:8080/spring-mvc-study这个正常显示

访问http://localhost:8080/spring-mvc-study/hello/mvc 就报404错误
