spring框架问题

Question

本人最近刚刚学习spring，遇到个棘手的问题，请各位大侠帮个忙，谢谢
我在配置页面跳转时发生Servlet Dispatcher is not available问题

我的web.xml文件如下：

<?xml version="1.0" encoding="UTF-8"?>
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">

<welcome-file-list>
    <welcome-file>index.html</welcome-file>
</welcome-file-list>

<servlet>
    <servlet-name>Dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/applicationContext.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>Dispatcher</servlet-name>
    <url-pattern>*.cgi</url-pattern>
</servlet-mapping>

applicationContext.xml文件内容如下：

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