Here is what I do for small projects with only marginal usage of method calls within the same class. In-code documentation is strongly advised, as it may look strange to colleagues. But it works with singletons, is easy to test, simple, quick to achieve and spares me the full blown AspectJ instrumentation. However, for more heavy usage I'd advice the AspectJ solution as described in Espens answer.

@Service
@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS)
class PersonDao {

    private final PersonDao _personDao;

    @Autowired
    public PersonDao(PersonDao personDao) {
        _personDao = personDao;
    }

    @Transactional
    public void addUser(String username, String password) {
        // call database layer
    }

    public void addUsers(List users) {
        for (User user : users) {
            _personDao.addUser(user.getUserName, user.getPassword);
        }
    }
}
