Question

I am using spring/hibernate. I have service layer and DAO layer. Transactions are placed in Service layer.
I have FirstServiceImpl class. In one of the method of FirstServiceImpl class it has 500 lines of code. what I did was I took all 500 lines of code and placed in a separate class(wrote one interface and implementation class. In the FirstServiceImpl class I autowired newly created interface to access its single method).
I placed @Transactional on FirstServiceImpl class.

My question is “does the newly created class logic also runs in Transactional context”?

Thanks!

I am not sure but I think it will use transaction propagation. But I can tell you sure way to test whether it works or not.

Do following database operation through your code in single transaction.

Insert/update one row into db, try to insert/update second row in the same transaction.

While inserting second row intentionally raise an exception. If you can see "first entry" in database, that means your transaction is not rolled back. And it does not work.

While if there is no first row entry in database, that means your transaction is rolled back. Here you may get UnexpectedRollbackException.

Before testing make sure your annotation is @Transactional(propagation=Propagation.REQUIRED)
