Не удалось лениво инициализировать набор ролей, не удалось инициализировать прокси - нет сеанса

У меня возникла проблема при ленивой загрузке. Это нормально работает с активной загрузкой. Ниже приведен код для applicationContext.xml

Я все перепробовал. Я думаю, что транзакционная аннотация не работает. Я использовал аннотацию @Transactional в своем классе обслуживания для метода. Вот мой класс обслуживания

@Override
    @Transactional
    public SchoolSessionDetail saveSchoolSession(SchoolSessionDetail sessionDetail) {
        List<SmsSchoolSession> sessions = smsSchoolSessionRepository.findBySmsSchool_IdOrderByStartDateDesc(loggedInSchool().getId());
        sessions.forEach(session->{
            if (session.getIsCurrent() == (byte)1) {
                session.setIsCurrent((byte)0);
                saveStudentArchive(session.getSmsClassroom(), session.getSmsStudentArchives());
            }
        });
        SmsSchoolSession session = createNewSchoolSession(sessionDetail);
        sessions.add(session);
        if (smsSchoolSessionRepository.save(sessions) != null) {
            SmsSchoolSession currentSession = smsSchoolSessionRepository.findByIsCurrentAndSmsSchool((byte)1, loggedInSchool());
            updateSchoolSession(currentSession);
            return new SchoolSessionDetail(currentSession);
        }
        return null;
    }

Пожалуйста, предложите мне решение для этого.
