Method Detail

doInTransaction

public final Object doInTransaction(TransactionStatus status)

Description copied from interface: TransactionCallback

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.

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. 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.

Specified by:

doInTransaction in interface TransactionCallback

Parameters:

status - associated transaction status

Returns:

a result object, or null
