Jdbi3: transaction with more than one dao and @Transaction annotation

I have to execute a transactions that involves methods in more than one dao, so I am using something like:

    jdbi.useHandle(handle -> {

        handle.useTransaction(h -> {

            Dao1 dao1 = h.attach(Dao1.class);
            Dao2 dao2 = h.attach(Dao2.class);
            dao1.method1();
            dao2.method2();
        });
    });

but if for example in Dao1 method1 is annotated with @Transaction, like:

public interface Dao1 {

   @SqlUpdate
   @Transaction
   public void method1();
}

The above handle parts will execute both the methods in the same transaction? Or method1 will open a new transaction during execution?

Do not use @Transaction annotation if you want to reuse DAO methods in another transaction. This makes slow performance and complicated checkpoints for rollbacks, if DBMS can support, it causes exceptions.
