Spring Transactions [closed]

Question

I have two dao methods and if these two methods are called separately by two different functions. How can i make the dao methods to be transactional(1 transaction two methods) so that if there is any error in second dao method both methods will be rolled back..

Answer 1

you wrap them in a service layer.

public interface MyTransactionalService{

  public void doStuff();

}

@Service
@Transactional
class MyTransactionalServiceImpl implements MyTransactionalService{

  @Autowired GenericDaoImpl<ClassOne> classOneDao;
  @Autowired GenericDaoImpl<ClassTwo> classTwoDao;

  // this method will be transactional
  public void doStuff(){
    classOneDao.doThis();
    classTwoDao.doThat();
  }

}
