Class LocalTransactionManagerLookup

java.lang.Object
  org.springframework.orm.hibernate.LocalTransactionManagerLookup

All Implemented Interfaces:

net.sf.hibernate.transaction.TransactionManagerLookup

public class LocalTransactionManagerLookup

extends java.lang.Object

implements net.sf.hibernate.transaction.TransactionManagerLookup

Implementation of Hibernate's TransactionManagerLookup interface that returns a Spring-managed JTA TransactionManager, determined by LocalSessionFactoryBean's "transactionManager" property.

The main advantage of this TransactionManagerLookup is that it avoids double configuration of JTA specifics. A single TransactionManager bean can be used for both JtaTransactionManager and LocalSessionFactoryBean, with no JTA setup in Hibernate configuration.

Alternatively, use Hibernate's own TransactionManagerLookup implementations: Spring's JtaTransactionManager only requires a TransactionManager for suspending and resuming transactions, so you might not need to apply such special Spring configuration at all.
