How to enable browser caching of static content(images, css, js) with Tomcat?

try (with changing the values)

<mvc:resources mapping="/static/**" location="/public-resources/" 
       cache-period="31556926"/>
<mvc:annotation-driven/>

You can also use an interceptor:

<mvc:interceptors>
   <mvc:interceptor>
    <mvc:mapping path="/static/*"/>
    <bean id="webContentInterceptor" 
         class="org.springframework.web.servlet.mvc.WebContentInterceptor">
        <property name="cacheSeconds" value="31556926"/>
        <property name="useExpiresHeader" value="true"/>
        <property name="useCacheControlHeader" value="true"/>
        <property name="useCacheControlNoStore" value="true"/>
    </bean>
   </mvc:interceptor>
</mvc:interceptors>
