Я написал код java, который отслеживает сбои транзакций. И чем обновить некоторые поля в базе данных.
@Stateless
@TransactionManagement(TransactionManagementType.BEAN)
public class TransactionObserver {
private static final Logger log = Logger.getLogger(TransactionObserver.class);
@PersistenceContext
private EntityManager em;
@Resource
private SessionContext ctx;
@Asynchronous
public void observeAfterTransactionFailed(@Observes(during = TransactionPhase.AFTER_FAILURE) @TransactionFailure Long id) {
log.error("-----------Transaction Failure Oserver Start");
try {
UserTransaction userTransaction = ctx.getUserTransaction();
userTransaction.begin();
TestEntity step = em.find(TestEntity.class, id);
userTransaction.commit();
}
catch (SecurityException e) {
log.error(e.getMessage());
}
}
Допустим, в этом примерном методе я просто найду объект и ничего с ним не сделаю.
Этот наблюдатель наблюдает за событием, которое вызывается внутри метод с аннотацией @TransactionTimeout(value = 1, unit = TimeUnit.SECONDS). Это работает нормально, когда я запускаю его на своем компьютере без точек останова.
Но когда я устанавливаю точку останова для метода observeAfterTrasactionFailed в классе Observer, я получаю сбой в сети, когда пытаюсь найти объект с моим EntityManager.
Мне кажется, что когда я пытался нормально работать, он проходил, потому что транзакция была откатана после запуска кода наблюдателя. Но поскольку я установил, что точка останова транзакции успевает завершиться, и чем-то новая транзакция не может создать новое соединение с базой данных.
У вас есть идеи, что я делаю неправильно?
