Level 2 caching for OneToOne associations in Hibernate

Solution Verified - Updated -

Issue

  • Entities between which there exist a @OneToOne association are marked cacheable
  • The @OneToOne association itself is marked with @Cache(...)
  • Access to the entities is resolved in cache (e.g. using EntityManager.find(<class>, <key>))
  • Each time the association is accessed in a new entity manager, a database query is observed

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP) 6,7
  • Hibernate 4,5
