I have a dao package where all my DaoClasses implements amongst others the following methode:
public class XDaoImpl implements XDao {
private SessionFactory sessionFactory;
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory = sessionFactory;
}
public SessionFactory getSessionFactory() {
return sessionFactory;
}
@Override
public void saveOrUpdate(MyObject o) {
//Transaction trans = getSessionFactory().getCurrentSession().beginTransaction();
getSessionFactory().getCurrentSession().saveOrUpdate(o);
//trans.commit();
}
}
If I run my application it needs a lot time to store my objects to the database. I belief it happens because I create a new Transaction for each object. So I tried to use Spring Framework’s xml based declarative transaction implementation. But till now it does not work for me:
