Examples with TransactionNotification org.mule.runtime.api.notification.TransactionNotification used on opensource projects

Example 1 with TransactionNotification

use of org.mule.runtime.api.notification.TransactionNotification in project mule by mulesoft.

the class TransactionNotificationsTestCase method testTransactionNotifications.

@Test
public void testTransactionNotifications() throws Exception {
    final CountDownLatch latch = new CountDownLatch(3);
    // the code is simple and deceptive :) The trick is this dummy transaction is handled by
    // a global TransactionCoordination instance, which binds it to the current thread.
    Transaction transaction = new DummyTransaction(muleContext);
    ((MuleContextWithRegistries) muleContext).getRegistry().lookupObject(NotificationListenerRegistry.class).registerListener(new TransactionNotificationListener<TransactionNotification>() {

        @Override
        public boolean isBlocking() {
            return false;
        }

        @Override
        public void onNotification(TransactionNotification notification) {
            if (new IntegerAction(TRANSACTION_BEGAN).equals(notification.getAction())) {
                assertEquals("begin", notification.getActionName());
                latch.countDown();
            } else if (new IntegerAction(TRANSACTION_COMMITTED).equals(notification.getAction())) {

                assertEquals("rollback", notification.getActionName());
                latch.countDown();
            }
        }
    }, notification -> transaction.getId().equals(notification.getResourceIdentifier()));
    transaction.begin();
    transaction.commit();
    transaction.rollback();
    // Wait for the notifcation event to be fired as they are queued
    latch.await(2000, MILLISECONDS);
    assertEquals("There are still some notifications left unfired.", 0, latch.getCount());
}
