Spring MVC disables caching for .js resource files

We have a bunch of .js files in a web application that are not located under the same directory. The user interface was developed separately, and it took quite a while to reorganize it to have all * .js files in one place.

The problem is that these files are very heavily cached by browsers, and this creates a lot of problems with every update of the application. And we decided to disable caching for these files.

So, the * .js files were included in the servlet mapping:

<servlet-mapping>
    <servlet-name>app</servlet-name>
    <url-pattern>*.js</url-pattern>
</servlet-mapping>

I tried using mvc: resources, but it does not handle url masks as follows:

<mvc:resources mapping="*.js" location="*.js" cache-period="0"/>

This does not work, and I have a 404 answer when I try to access the js file.

I also tried mvc: interceptor:

    <mvc:interceptor>
        <mvc:mapping path="*.js"/>
        <bean id="webJSContentInterceptor"
              class="org.springframework.web.servlet.mvc.WebContentInterceptor">
            <property name="cacheSeconds" value="0"/>
            <property name="useExpiresHeader" value="true"/>
            <property name="useCacheControlHeader" value="true"/>
            <property name="useCacheControlNoStore" value="true"/>
        </bean>
    </mvc:interceptor>

This also results in a 404 error.

Is it possible?
