Spring mapping

在练习搭SPRING框架的时候 碰到的问题：
Sep 21, 2009 1:23:16 PM org.springframework.web.servlet.DispatcherServlet noHandlerFound
WARNING: No mapping for [/Demo/index.html] in DispatcherServlet with name 'Demo'

但是在

<servlet>

		<servlet-name>Demo</servlet-name>

		<servlet-class>

			org.springframework.web.servlet.DispatcherServlet

		</servlet-class>

		<init-param>

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

			<param-value>

				/WEB-INF/classes/applicationContext.xml

			</param-value>

		</init-param>

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

	</servlet>

	<servlet-mapping>

		<servlet-name>Demo</servlet-name>

		<url-pattern>*.xhtml</url-pattern>

	</servlet-mapping>

	<servlet-mapping>

		<servlet-name>Demo</servlet-name>

		<url-pattern>*.html</url-pattern>

	</servlet-mapping>

applicationContext.xml 里面也配置好了　

<bean id="SimpleUrlMapping"

		class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">

		<property name="interceptors">

			<list>

				<ref bean="sessionInViewInterceptor" />

			</list>

		</property>

		<property name="mappings">

			<props>			

				<prop key="**/Demo/index.html">Demo.HomeController</prop>

			

			</props>

		</property>

		<property name="order">

			<value>1</value>

		</property>

	</bean>

但是还是报没有ＭＡＰＰＩＮＧ　　哪位大侠来指点下　谢谢
