Ehcache refreshed at request time

[gcorro]

Hi,


I have my EhCache being refreshed each 24 hrs as you can see in the snippet below:

<ehcache>
<!-- Required elements -->
<diskStore path="/MQ/programs/xxx/"/>
<defaultCache
maxElementsInMemory="10000"
eternal="false"
timeToIdleSeconds="86400"
timeToLiveSeconds="86400"
overflowToDisk="true"/>
</ehcache>


I wonder if there's a way to mandate to EhCache that it has to refresh the cache in a given moment, I mean, consider I have a web page with a button that says "Refresh Cache Now" so the cache does not have to wait 24 hrs after the last update.

Thanks!

I would guess you want to call clear.

Thanks for your replay, however considering I have my cache configured in the way described below, How could I get a reference to the EhCache interface?

<bean id="mySessionFactory"
class="org.springframework.orm.hibernate3.LocalSes sionFactoryBean">
<property name="dataSource" ref="myDataSource" />
<property name="mappingResources">
<list>
<value>resources/hibernate/Agents.hbm.xml</value>
<value>resources/hibernate/CAgents.hbm.xml</value>
<value>resources/hibernate/Passes.hbm.xml</value>
<value>resources/hibernate/VersionsForm.hbm.xml</value>
<value>resources/hibernate/Aut.hbm.xml</value>
<value>resources/hibernate/MsgMgr.hbm.xml</value>
<value>resources/hibernate/IntAut.hbm.xml</value>
<value>resources/hibernate/ExpInt.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.Orac le9Dialect</prop>
<prop key="hibernate.cache.provider_class"> org.hibernate.cache.EhCacheProvider</prop>
<prop key="hibernate.cache.use_query_cache">true</prop>
<prop key="hibernate.cache.provider_configuration_file_r esource_path">resources/Ehcache.xml</prop>
</props>
</property>
</bean>

Ahhh I see your problem. I'm not sure if you can get at the cache or not, I'd have a look at the JavaDoc.

You can get it through the Hibernate API :

http://www.hibernate.org/hib_docs/v3...e/EhCache.html

Otherwise I suppose you can get it with the ehcache API, but since ecache 1.2 the ehcache manager isn't a singleton anymore, so you have to know its instance name (and I have no idea what this name is...) :

Is there an example where Spring + Hibernate + EhCache + a chance to manipulate the cache through a config file and/or direct cache refresh somewhere? Thanks!

I'm sure there's a bug in JIRA about injecting in the Hibernate cache through LocalSessionFactoryBean. There might have even been a patch attached to it. This would make the whole thing a lot easier.
