I am writing webapp and trying to cache some pojos called from the controller.
I was not able to get anything to work when I tried to use org.springframework.cache.annotation.Cacheable, so I switched to com.googlecode.ehcaceh.annotations.Cacheable and I still can’t cache it.
My code is as follows:
@Controller
public class Conttroller {
@RequestMapping(method = RequestMethod.GET)....
public Person getPerson(String id) {
LOG.debug("Trying to get resource...);
Person person = personService.detect(id);
LOG.debug("got person");
and the service looks like this:
public class PersonService {
@Cacheable(cacheName="deviceCache")
public Person detect(String id) {
LOG.debug("cache missed")
My applicationContext looks like
<context:component-scan base-package="com.mycompany" />
<ehcache:annotation-driven cache-manager="ehCacheManager" />
<bean id="cacheManager" class="org.springframework.cache.ehcache.EhCacheCacheManager">
<property name="cacheManager">
<ref bean="ehCacheManager" />
</property>
</bean>
<bean id="ehCacheManager" class="org.springframework.cache.ehcache.EhCacheManagerFactoryBean" p:configLocation="/META-INF/ehcache.xml" />
and my ehcache looks like this:
<defaultCache eternal="false" maxElementsInMemory="1000"
overflowToDisk="false" diskPersistent="false" timeToIdleSeconds="0"
timeToLiveSeconds="600" memoryStoreEvictionPolicy="LRU"/>
<cache name="deviceCache"
maxElementsInMemory="100" overflowToDisk="false" diskPersistent="false"
timeToIdleSeconds="0" timeToLiveSeconds="300"
memoryStoreEvictionPolicy="LRU" />
Interestingly, it caches my unit test perfectly ...
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration({"classpath:META-INF/applicationContext-test.xml"})
public class PersonServiceTest {
private static final Logger LOG = LoggerFactory.getLogger(PersonServiceTest.class);
@Test
public void testCache() {
LOG.debug("Getting person...");
Device detect = personService.detect("test");
LOG.debug("Getting person again ...");
detect = personService.detect("test");
LOG.debug("Done");
}
which produces:

13:45:02.887 [main] DEBUG c.g.e.a.i.CacheAttributeSourceImpl - Adding CACHE advised method 'detect' with attribute: CacheableAttributeImpl [cacheInstanceResolver=com.googlecode.ehcache.annotations.resolver.SingletonCacheableCacheResolver@5c2bfdff, cacheKeyGenerator=HashCodeCacheKeyGenerator [includeMethod=true, includeParameterTypes=true, useReflection=false, checkforCycles=false], parameterMask=ParameterMask [mask=[]]]

But the output of my war (passing through tomcat7 / eclipse wtp):

So my question is: why does it work in my unit test and not in webapp? And how can I use spring annotation instead of googlecode annotation?
