Hi,
In Hibernate when i save() an
object in a transaction, and then i rollback it, the saved
object still remains in the DB. It's strange because this issue doesn't happen with the update() or delete() method, just with save().
Here is the code i'm using:
DbEntity dbEntity = getDbEntity();
HibernateUtil.beginTransaction();
Session session = HibernateUtil.getCurrentSession();
session.save(dbEntity);
HibernateUtil.rollbackTransaction();
And here is the HibernateUtil class (just the involved functions, i guarantee the getSessionFactory() method works well - there is an Interceptor handler, but it doesn't matter now):
private static final ThreadLocal<Session> threadSession = new ThreadLocal<Session>();
private static final ThreadLocal<Transaction> threadTransaction = new ThreadLocal<Transaction>();
/**
* Retrieves the current Session local to the thread.
* <p/>
* If no Session is open, opens a new Session for the running thread.
*
* @return Session
*/
public static Session getCurrentSession()
throws HibernateException {
Session s = (Session) threadSession.get();
try {
if (s == null) {
log.debug("Opening new Session for this thread.");
if (getInterceptor() != null) {
log.debug("Using interceptor: " + getInterceptor().getClass());
s = getSessionFactory().openSession(getInterceptor());
} else {
s = getSessionFactory().openSession();
}
threadSession.set(s);
}
} catch (HibernateException ex) {
throw new HibernateException(ex);
}
return s;
}
/**
* Start a new database transaction.
*/
public static void beginTransaction()
throws HibernateException {
Transaction tx = (Transaction) threadTransaction.get();
try {
if (tx == null) {
log.debug("Starting new database transaction in this thread.");
tx = getCurrentSession().beginTransaction();
threadTransaction.set(tx);
}
} catch (HibernateException ex) {
throw new HibernateException(ex);
}
}
/**
* Rollback the database transaction.
*/
public static void rollbackTransaction()
throws HibernateException {
Transaction tx = (Transaction) threadTransaction.get();
try {
threadTransaction.set(null);
if ( tx != null && !tx.wasCommitted() && !tx.wasRolledBack() ) {
log.debug("Tyring to rollback database transaction of this thread.");
tx.rollback();
}
} catch (HibernateException ex) {
throw new HibernateException(ex);
} finally {
closeSession();
}
}
Thanks
