Spring annotation cache: CacheDecoratorFactory not

Question

I'm trying to use Sping Annotation cache with EhCache. So, for first, I added the dependency to my pom.xml and configured the application-context.xml as:

<ehcache:annotation-driven cache-manager="cacheManager" />

<ehcache:config cache-manager="cacheManager">
    <ehcache:evict-expired-elements interval="60" />
</ehcache:config>

<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean">
    <property name="configLocation"  value="ehcache.xml"/>
</bean>

This is the ehcache.xml configuration file:

<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">
    <defaultCache eternal="true" maxElementsInMemory="100" overflowToDisk="false" />
    <cache name="alfresco" maxElementsInMemory="10" eternal="true" overflowToDisk="false" />
</ehcache>

for last, I added the Annontation @Cachable to the methods that need to be cached:

@Cacheable(value="alfresco")
public EMContents getContents(RestTemplate restTemplate, String ticket, String webScriptUrl, String em_name)

I create a junit class to call two times the same method, and, it doesn't use the cache the second time (the first one doesn't create the key value).

It seems to work fine, but I get this message:

Any clue? Something seems to be wrong with my configuration.

Thanks for your time

Andrea,

Make sure that the instance of the bean with the @Cachable annotation is the spring managed one, not one you are creating yourself. If you have the right one the log will produce something like this when the method is invoked:

2012-11-16 09:40:21,731 [http-8081-2] DEBUG com.googlecode.ehcache.annotations.interceptor.EhCacheInterceptor  - Generated key '1396312488991822982' for invocation: ReflectiveMethodInvocation: public edu.wmich.gowmu.sso.dataobject.User edu.wmich.gowmu.sso.bl.UserManager.getUser(java.lang.String,java.lang.String); target is of class [edu.wmich.gowmu.sso.bl.UserManager]
