Я хочу проверить сущности перед их сохранением / обновлением.Для этого я использую аннотации @PrePersist и @PreUpdate и выкидываю исключение для отката транзакции.Затем я ловлю исключение и информирую пользователя о том, что объект недействителен.Все работает нормально для @PrePersist, но @PreUpdate заполняет журнал предупреждением и трассировкой стека, прежде чем я могу поймать исключение.
Тестовый объект:
@Entity
public class TestEntity implements Serializable {
private static final long serialVersionUID = 1L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)
private Long id;
private String name = "default";
@PrePersist
private void prePersist() { throw new RuntimeException("Test runtime exception in prePersist"); }
@PreUpdate
private void preUpdate() { throw new RuntimeException("Test runtime exception in preUpdate"); }
public String getName() { return name; }
public void setName(String name) { this.name = name; }
}
Бин сеанса тестирования:
@Stateless
@LocalBean
public class TestSession {
private static final Logger logger = Logger.getLogger("TestSession");
@PersistenceContext
private EntityManager em;
@Resource
private SessionContext ctx;
public void testRollback() {
try {
TestEntity entity = new TestEntity();
em.persist(entity);
} catch (RuntimeException ex) {
logger.severe("Runtime exception catched in session bean.");
if (ctx.getRollbackOnly()) {
logger.info("Context rollbacked.");
} else {
logger.info("Context is ok.");
}
}
}
public void testRollback2() {
try {
TestEntity entity = em.find(TestEntity.class, new Long(1));
if (entity != null) { entity.setName("test"); }
em.flush();
} catch (RuntimeException ex) {
logger.severe("Runtime exception catched in session bean.");
if (ctx.getRollbackOnly()) {
logger.info("Context rollbacked.");
} else {
logger.info("Context is ok.");
}
}
}
}
Вывод при вызове testRollback:
GRAVE: Runtime exception catched in session bean.
INFO: Context rollbacked.
Вывод при вызове testRollback2:
ATTENTION: java.lang.RuntimeException: Test runtime exception in preUpdate

Похоже, что журнал генерируется eclipselink.Как я должен обрабатывать откат транзакции внутри метода @PrePersist, чтобы избежать всей этой регистрации?
