Have you had experience using the @Transactional annotation in your projects?

The @Transactional annotation in Java is used for managing transactions at the method or class level. It ensures that all operations within the method are executed as a single unit: either all succeed (commit) or, in case of an error, are rolled back (rollback).

Example of usage:

@Service
public class UserService {

    @Transactional
    public void createUserAndAccount(User user, Account account) {
        userRepository.save(user);
        accountRepository.save(account);
        // If an exception occurs here, both operations will be rolled back
    }
}

Thus, @Transactional helps ensure data integrity and simplifies transaction management.
