@Transactional method calling another method without @Transactional anotation?

Question

I\'ve seen a method in a Service class that was marked as @Transactional, but it was also calling some other methods in that same class which were not marked as

Answer 1

The inner method will affect the outer method if the inner method is not annotated with @Transactional.

In case inner method is also annotated with @Transactional with REQUIRES_NEW, following will happen.

...
@Autowired
private TestDAO testDAO;

@Autowired
private SomeBean someBean;

@Override
@Transactional(propagation=Propagation.REQUIRED)
public void outerMethod(User user) {
  testDAO.insertUser(user);
  try{
    someBean.innerMethod();
  } catch(RuntimeException e){
    // handle exception
  }
}


@Override
@Transactional(propagation=Propagation.REQUIRES_NEW)
public void innerMethod() {
  throw new RuntimeException("Rollback this transaction!");
}

The inner method is annotated with REQUIRES_NEW and throws a RuntimeException so it will set its transaction to rollback but WILL NOT EFFECT the outer transaction. The outer transaction is PAUSED when the inner transaction starts and then RESUMES AFTER the inner transaction is concluded. They run independently of each other so the outer transaction MAY commit successfully.
