Dispatcher servlet - url mapping

I have my dispatcher servlet url mapping configuration like this below
<bean id="uriMapping" class="org.springframework.web.servlet.handler.Sim pleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/page1.html">firstController</prop>
<prop key="/page2.html">secondController</prop>
<prop key="/page3.html">thirdController</prop>
</props>
</property>
</bean>

Everything works fine, but I need to add one more entry in <props> tag. I need to hava sht like this:

<prop key="/htmlPagesDir/**/*.html">forwardingController</prop>

just to enable url's with /htmlPagesDir/ prefix and .html extenstion directly accessing my html pages withing webapp/htmlPagesDir

What kind of controller to use, thank you for any help...
