Class ExtendedEntityManagerCreator

java.lang.Object
  extended by org.springframework.orm.jpa.ExtendedEntityManagerCreator

public abstract class ExtendedEntityManagerCreator
extends java.lang.Object

Factory for dynamic EntityManager proxies that follow the JPA spec's semantics for "extended" EntityManagers.

Supports explicit joining of a transaction through the joinTransaction() method ("application-managed extended EntityManager") as well as automatic joining on each operation ("container-managed extended EntityManager").

2.0

exceptionTranslator - the exception translator to use for translating JPA commit/rollback exceptions during transaction synchronization (may be null)
Returns:
an application-managed EntityManager that can join transactions but does not participate in them automatically

createApplicationManagedEntityManager

public static javax.persistence.EntityManager createApplicationManagedEntityManager(javax.persistence.EntityManager rawEntityManager,

Create an EntityManager that can join transactions with the joinTransaction() method, but is not automatically managed by the container.

Parameters:
rawEntityManager - raw EntityManager
emfInfo - the EntityManagerFactoryInfo to obtain the EntityManagerPlusOperations and PersistenceUnitInfo from
