如何使用Tomcat启用静态内容(images,css,js)的浏览器缓存？

<!-- Default servlet -->
<servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
    <init-param>
        <param-name>debug</param-name>
        <param-value>0</param-value>
    </init-param>
    <init-param>
        <param-name>listings</param-name>
        <param-value>false</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<!-- Enable browser caching for static content -->
<init-param>
    <param-name>cacheControl</param-name>
    <param-value>max-age=3600, public</param-value>
</init-param>
