Nested @Transactional

Question

Is it possible to nest @Transactional annotated methods in spring? Consider something like this:

@Transactional
public void a() {
    obj.b();
}

@Transactio         


        

Answer 1

The second @Transactional annotation on method b() is not required because by default @Transactional has a propagation of REQUIRED, therefore methods called by method a() will be transactional. If you are looking to start a new transaction within a method called by method a() you will need to modify the propagation rules. Read about Transaction Propagation.
