Configuring Using the Transaction Template
The following configuration shows how TmfTransactionManager can be used in a Spring
Transaction Template:
ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(“txbean.xml");
transactionTemplate = new TransactionTemplate(transactionManager);
transactionTemplate.execute(new TransactionCallback()
{
// the code in this method executes in a transactional context
public Object doInTransaction(TransactionStatus status)
{
//code to invoke the POJO Service for example.
//it can be new SimpleService().addRecord();
//then add record will be executed in a TMF Transaction.
}
});
Configuring Using the TmfTransactionManager Programmatically
The following configuration shows how TmfTransactionManager can be created
programmatically and used in a TMF transaction:
public class SimpleService {
public void addRecord(SimpleBean b){
DefaultTransactionDefinition def = new DefaultTransactionDefinition();
/* setting the transaction name explicitly can only be done programmatically*/
def.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);
TransactionStatus status = txManager.getTransaction(def);
try {
//code to invoke the POJO Service for example.
//it can be new SimpleService().addRecord();
//then add record will be executed in a TMF Transaction.
txManager.commit(status);
}
catch (MyException ex)
{
txManager.rollback(status);
throw ex;
}
}
}
