 org.springframework.orm.jpa.SharedEntityManagerCreator
| SharedEntityManagerCreator | | abstract public class SharedEntityManagerCreator (Code) | | Factory for a shared JPA EntityManager for a given EntityManagerFactory.
The shared EntityManager will behave just like an EntityManager fetched
from an application server's JNDI environment, as defined by the JPA
specification. It will delegate all calls to the current transactional
EntityManager, if any; else, it will fall back to a newly created
EntityManager per operation.
