Great post thank you. But I have a question; I can’t remove the cached query from the cache! I need to refresh the cache after performing data changes.

The point is that the Entity Manager is part of JPA and JPA does not define those nice caching methods. However as Shervin wrote you can use the hints methods to pass this on to hibernate.

Caching is a bit of a neglected part of JPA – also of JPA 2.0 as it seems right now.

@Michael, what you can do is on the query you create, you can say:

entityManager.createQuery(“select person from person”).setHint(“org.hibernate.cacheable”, true).getResultList();

Then it will enable the query caching.
Hope this helps.

Hi,
I am using hibernate entity manager.
I wanted to use the query cache as you explained above, but Query returned by entity manager createQuery() method does not support setCacheable() ability.
