Cache not flushed

[eboix]

Hi all,

I'm using the OSCache integration from SprindModules, and it really improves the performance of the app, but I can't get the cache to flush.

Here goes an excerpt of the config:

	<bean id="baseDao"    class="org.springmodules.cache.interceptor.proxy.CacheProxyFactoryBean">
	    <property name="cacheProviderFacade">
		<ref local="cacheProvider" />
	    </property>
	    <property name="cachingAttributes">
		<props>
		     <prop key="obtenirTotesFasesProduccio">[cacheProfileId=cacheWheels]</prop>
		</props>
	    </property>
	    <property name="cacheFlushAttributes">
		<props>
		    <prop key="actualitzarFase">[cacheProfileIds=cacheWheels][flushBeforeExecution=true]</prop>
		</props>
	    </property>
	    <property name="target">
		<ref bean="baseDaoTarget"/>
	    </property>
	</bean>

...the idea is to cache results from "obtenirTotesFasesProduccio", and flush before executing "actualitzarFase" in "baseDaoTarget".

I've enable debugging:

The first call gets cached:

2006-02-10 12:58:43,818 DEBUG [org.springframework.transaction.support.TransactionSynchronizationManager] - Initializing transaction synchronization

2006-02-10 12:58:43,819 DEBUG [org.springmodules.cache.provider.AbstractCacheProviderFacadeImpl] - Method 'getFromCache(CacheKey, String)'. Variable 'cachedObject': null

Later, a call to "actualitzarFase" generates the following log (so the cache seems to be cleared):

2006-02-10 12:58:50,031 DEBUG [org.springframework.transaction.support.TransactionSynchronizationManager] - Initializing transaction synchronization

But a later call to "obtenirFasesProduccio" gets again the first cached value from the cache:

Anyone is using OSCache with Spring ? Maybe I should try another cache impl ?

Hi all,

Well, I simply changed from OSCache to JCS and everything is going well... I've lost the CronExpression feature though.

Then there might be an issue with OSCache. Post your problem on spring modules mailing list just in case - Alex, the maintainer, can probably help you out.
