최대 절전 모드 트랜잭션 블록 문제

Question

내 관련 DAO 클래스

@Autowired 개인의 SessionFactory sessionFactory의에서 코드;

public void getTabletbyNameAndSave(String []selectedMedicines) { 
    sessionFactory.getCurrentSession().beginTransaction(); 
    EPrescriber ePrescriber=new EPrescriber(); 
    List<SelectedTablets> selectedTabletsList=new ArrayList<SelectedTablets>(); 
    for (String item : selectedMedicines) { 

     Tablets tablets=null; 
     String hql="from Tablets t where t.category='"+item.trim()+"' "; 
     Query queryList = sessionFactory.getCurrentSession().createQuery(hql); 
     tablets=(Tablets)queryList.uniqueResult(); 

     SelectedTablets selectedTablets=new SelectedTablets(); 
     selectedTablets.setTablets(tablets); 
     selectedTablets.setePrescriberid(ePrescriber); 
     selectedTabletsList.add(selectedTablets); 
     sessionFactory.getCurrentSession().save(selectedTablets); 

    } 

    ePrescriber.setPatientName("Kasun"); 
    ePrescriber.setSelectedTablets(selectedTabletsList); 
    sessionFactory.getCurrentSession().save(ePrescriber); 
    sessionFactory.getCurrentSession().getTransaction().commit();  
} 

여기에 오류가 있습니다. 내 트랜잭션 블록이 올바르게 처리되지 않은 것으로 보입니다. 이 문제에 대해 조언 해주십시오. 감사!

로컬 트랜잭션에 수동으로 트랜잭션을 할당하여 올바른 트랜잭션에서 최종 커밋을 실행하려고합니다. 다음과 같은 것 :

@Autowired private SessionFactory sessionFactory; 

public void getTabletbyNameAndSave(String []selectedMedicines) { 

    Session currentSession = sessionFactory.getCurrentSession(); 
    Transaction tx = currentSession.beginTransaction(); 

    EPrescriber ePrescriber=new EPrescriber(); 
    List<SelectedTablets> selectedTabletsList=new ArrayList<SelectedTablets>(); 
    for (String item : selectedMedicines) { 

     Tablets tablets=null; 
     String hql="from Tablets t where t.category='"+item.trim()+"' "; 
     Query queryList = currentSession.createQuery(hql); 
     tablets=(Tablets)queryList.uniqueResult(); 

     SelectedTablets selectedTablets=new SelectedTablets(); 
     selectedTablets.setTablets(tablets); 
     selectedTablets.setePrescriberid(ePrescriber); 
     selectedTabletsList.add(selectedTablets); 
     currentSession.save(selectedTablets); 

    } 

    ePrescriber.setPatientName("Kasun"); 
    ePrescriber.setSelectedTablets(selectedTabletsList); 
    currentSession.save(ePrescriber); 
    tx.commit();  
}
