EHCache Singleton CacheManager

Here's the problem, when we enable the hibernate secondary cache using org.hibernate.cache.EHCacheProvider, and enable ACEGI user cache using

<property name="userCache">
<bean class="org.acegisecurity.providers.dao.cache.EhCacheBasedUserCache">
<property name="cache">
<bean class="org.springframework.cache.ehcache.EhCacheFactoryBean">
<property name="cacheName" value="AcegiUserCache">
</property>
</bean>
</property>
</bean>
</property>

They belongs to two different cache manager.

Instead of have to configure 2 different cache manager separately, have to have separate cache invalidating thread etc, we can fall back to the EHCache Singleton CacheManager.

hibernate.cache.provider_class=net.sf.ehcache.hibernate.SingletonEhCacheProvider

Now ACEGI will use the same EHCache CacheManager. They can be configured in the same ehcache.xml file. Yup!
