springmvc静态资源配置没起作用:配置报错

    <beans:bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

        <beans:property name="prefix" value="/WEB-INF/views/"/>

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

    </beans:bean>

    <resources mapping="/static/**" location="/static/" />

    <view-controller path="/" view-name="redirect:/index.do"/>

    </interceptors>

</beans:beans>
为什么我配置的
<resources mapping="/static/**" location="/static/" />     <view-controller path="/" view-name="redirect:/index.do"/>
这两项都不起作用呢，通过/static/js/common.js都返回不了，所有static目录下的内容都不返回。
哪位高手帮忙看看啊
