two methods in one transaction

Question

I have a DAO class with two following methods:

@Transactional
public void save() throws Exception {

}

@Transactional
public void save2() {

}

In the service class I call those methods as follows:

public void processDAO() {
    dao.save();
    dao.save2();
}

My question is, will those methods run as part of the same transaction or in independent transactions or none of these?

Thanks and best regards,

Answer 1

If the processDAO() method or the class of this method or a method/class which is higher in the call stack is also annotated with @Transactional, then they will run in the same transaction, otherwise in two different transactions.
