Method Detail

doInTransaction

public final java.lang.Object doInTransaction(TransactionStatus status)
Description copied from interface: TransactionCallback
Gets called by TransactionTemplate.execute(org.springframework.transaction.support.TransactionCallback) within a transactional context. Does not need to care about transactions itself, although it can retrieve and influence the status of the current transaction via the given status object, e.g. setting rollback-only.

Allows for returning a result object created within the transaction, i.e. a domain object or a collection of domain objects. A RuntimeException thrown by the callback is treated as application exception that enforces a rollback. Any such exception will be propagated to the caller of the template, unless there is a problem rolling back, in which case a TransactionException will be thrown.

Specified by:
doInTransaction in interface TransactionCallback<java.lang.Object>
Parameters:
status - associated transaction status
Returns:
a result object, or null

doInTransactionWithoutResult

protected abstract void doInTransactionWithoutResult(TransactionStatus status)
Gets called by TransactionTemplate.execute within a transactional context. Does not need to care about transactions itself, although it can retrieve and influence the status of the current transaction via the given status object, e.g. setting rollback-only.

A RuntimeException thrown by the callback is treated as application exception that enforces a rollback. An exception gets propagated to the caller of the template.

Note when using JTA: JTA transactions only work with transactional JNDI resources, so implementations need to use such resources if they want transaction support.

Parameters:
status - associated transaction status
