no as far as you know you can't. But why worring ? the AS takes care of saving resources. You can fine tune the idle time with the @CacheConfig annotation. The idleTimeoutSeconds parameter configures the amount of idle time before the bean is passivated and the removalTimeoutSeconds configures the amount of idle time before the bean is permanently removed.
