Loading selected Hibernate entities with JPA & Spring

Is there a way to loa开发者_StackOverflow社区d only selected entities with Hibernate?

I would like to only load a selected handful for integration testing.

I create an AnnotationConfiguration programatically for this kind of tests and use methods such as addAnnotatedClass(Class) to "enlist" entities.

I ended up using a custom persistence.xml and gave it to the EntityManagerFactory in the spring config.
