Example 3 with TransactionListener

use of org.activiti.engine.impl.cfg.TransactionListener in project Activiti by Activiti.

the class StandaloneMybatisTransactionContext method fireTransactionEvent.

/**
 * Fires the event for the provided {@link TransactionState}.
 *
 * @param transactionState The {@link TransactionState} for which the listeners will be called.
 * @param executeInNewContext If true, the listeners will be called in a new command context.
 *                            This is needed for example when firing the {@link TransactionState#COMMITTED}
 *                            event: the transacation is already committed and executing logic in the same
 *                            context could lead to strange behaviour (for example doing a {@link SqlSession#update(String)}
 *                            would actually roll back the update (as the MyBatis context is already committed
 *                            and the internal flags have not been correctly set).
