Доброго времени суток. Есть код:

@Controller
public class MainController {
    private int callsNum = 0;
    @RequestMapping(value = "/", method = RequestMethod.GET)
    @Transactional
    public String helloWorld() {
        System.out.println(++callsNum);
        return "home";
    }
}

При развертывании приложения контроллер вызывается 3 раза:

В чём может быть проблема?
