Class SharedSessionCreator

java.lang.Object

org.springframework.orm.jpa.hibernate.SharedSessionCreator

public abstract class SharedSessionCreator
extends Object

Delegate for creating shareable Session/StatelessSession references for a given SessionFactory.

Typically used next to LocalSessionFactoryBuilder. Note that LocalSessionFactoryBean exposes shared Session as well as StatelessSession references for dependency injection already, avoiding the need to define separate beans for the shared sessions.

7.0

Method Details

createSharedSession

public static Session createSharedSession(SessionFactory sessionFactory)

Create a shared Session proxy for the given SessionFactory.

The returned instance behaves like SessionFactory.getCurrentSession() but without the manual get call, automatically delegating every Session method invocation to the current thread-bound transactional session instance. Designed to work with HibernateTransactionManager as well as JTA.

Alternatively, use SessionFactory.getCurrentSession() directly.

Parameters:

sessionFactory - the SessionFactory to build the Session proxy for

createSharedStatelessSession

public static StatelessSession createSharedStatelessSession(SessionFactory sessionFactory)

Create a shared StatelessSession proxy for the given SessionFactory.

The returned instance automatically delegates every StatelessSession method invocation to the current thread-bound transactional session instance. On the first invocation within a new transaction, a StatelessSession will be opened for the current transactional JDBC Connection.

Works with HibernateTransactionManager (side by side with a thread-bound regular Session that drives the transaction) as well as JdbcTransactionManager or JtaTransactionManager (with a plain StatelessSession on top of a transactional JDBC Connection).

Alternatively, call SpringSessionContext.currentStatelessSession(SessionFactory) for every operation, avoiding the need for a proxy.

Parameters:

sessionFactory - the SessionFactory to build the StatelessSession proxy for
