使用Spring MVC，Tomcat应用程序为静态资源启用浏览器缓存

Question

I am using Tomcat-7, Spring-4, Hibernate-4 in my application. I have tried two approaches to make caching work but they don't seem to be working when I checked with gtmetrix .

Approach-1 using .htaccess file:

<IfModule mod_expires.c>
  ExpiresActive On
  ExpiresByType image/jpg "access 1 year"
  ExpiresByType image/jpeg "access 1 year"
  ExpiresByType image/gif "access 1 year"
  ExpiresByType image/png "access 1 year"
  ExpiresByType text/css "access 1 month"
  ExpiresByType application/pdf "access 1 month"
  ExpiresByType application/x-javascript "access 1 month"
  ExpiresByType application/x-shockwave-flash "access 1 month"
  ExpiresByType image/x-icon "access 1 year"
  ExpiresDefault "access 2 days"
</IfModule>

Approach-2 using Spring MVC xml Config mvc:interceptors :

<mvc:interceptors>
   <mvc:interceptor>
        <mvc:mapping path="/resources/*"/>
        <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>

What are the other approaches that I can use with Tomcat, Spring-MVC to make browser caching work ?
Please share your experience.

Answer 1

The other approach is this:

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