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

    <!--为DispatcherServlet建立映射 -->
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

SpringMVC另外一个重要的配置文件。
DispatcherServlet会根绝web.xml中配置的<servlet-name>去找<servlet-name>-servlet.xml的文件来加载spring的一些配置信息。我这里就应该取名叫springmvc-servlet.xml
