Class Neo4jTransactionManager

java.lang.Object

org.springframework.transaction.support.AbstractPlatformTransactionManager

org.springframework.data.neo4j.transaction.Neo4jTransactionManager

All Implemented Interfaces:

Serializable, Aware, BeanFactoryAware, InitializingBean, PlatformTransactionManager, ResourceTransactionManager

public class Neo4jTransactionManager
extends AbstractPlatformTransactionManager
implements ResourceTransactionManager, BeanFactoryAware, InitializingBean

PlatformTransactionManager implementation for a single Neo4j OGM SessionFactory. Binds a Neo4j OGM Session from the specified factory to the thread, potentially allowing for one thread-bound Session per factory. SharedSessionCreator is aware of thread-bound session and participates in such transactions automatically. It is required for Neo4j OGM access code supporting this transaction management mechanism.

This transaction manager is appropriate for applications that use a single Neo4j OGM SessionFactory for transactional data access. JTA (usually through JtaTransactionManager) has not been tested or considered at the moment.

This transaction manager does not support nested transactions or requires new propagation.

Constructor Detail

Neo4jTransactionManager

public Neo4jTransactionManager()

Create a new Neo4jTransactionManager instance.

An SessionFactory has to be set to be able to use it.

See Also:

setSessionFactory(SessionFactory)

Neo4jTransactionManager

public Neo4jTransactionManager(org.neo4j.ogm.session.SessionFactory sessionFactory)

Create a new Neo4jTransactionManager instance.

Parameters:

sessionFactory - SessionFactory to manage transactions for

Method Detail

setSessionFactory

public void setSessionFactory(org.neo4j.ogm.session.SessionFactory sessionFactory)

Set the SessionFactory that this instance should manage transactions for.

By default, a default SessionFactory will be retrieved by finding a single unique bean of type SessionFactory in the containing BeanFactory.

getSessionFactory

public org.neo4j.ogm.session.SessionFactory getSessionFactory()

Return the SessionFactory that this instance should manage transactions for.

setBeanFactory

public void setBeanFactory(BeanFactory beanFactory)
                    throws BeansException

Retrieves a default SessionFactory bean.

Specified by:

setBeanFactory in interface BeanFactoryAware

Throws:
