Null Pointer Ausnahme in SessionFactory, wenn @Autowired Spring + Hibernate + Annotation

Ich versuche den folgenden Code, um Daten aus dem Postboten zu holen und in DB zu speichern. Aber die nullPointerException tritt auf.Null Pointer Ausnahme in SessionFactory, wenn @Autowired Spring + Hibernate + Annotation

Die web.xml ist als

Das ist mein DAO Impl Code

@Repository 
public class AddBeneficiaryDaoImpl implements AddBeneficiaryDao { 
    private SessionFactory sessionFactory; 

    @Autowired 
    public void setSessionFactory(SessionFactory sessionFactory) { 
     this.sessionFactory = sessionFactory; 

    } 

    @Override 
    public void insertBeneRegistration(AddBeneficiaryModel beneDetails) { 
     System.out.println("Inside insertBeneRegistration"); 
     System.out.println("Session Factory " + sessionFactory); 
     Session session = sessionFactory.openSession(); 
     System.out.println("session : " + session); 
     try { 
      Transaction tx = session.beginTransaction(); 
      session.save(beneDetails); 
      tx.commit(); 
     } finally { 
      session.close(); 
     } 

    } 
}

Der Fehler ist wie folgt s

Bitte gehen Sie durch. Wenn etwas anderes erforderlich ist, fragen Sie bitte, werde ich aktualisieren

Vielen Dank im Voraus

Ihre 'sessionFactory' null ist. Wo konfigurieren Sie die Bean 'sessionFactory'? Es sollte in einer 'xml' Konfigurationsdatei aline wie folgt gewesen sein: '' – pleft

Sollte ich es in spring-servlet.xml hinzufügen ? –

Benötigt viel mehr Konfiguration, ein Beispiel finden Sie hier: http://www.baeldung.com/hibernate3-spring – pleft

Fügen Sie diese in Ihrem applicationContext.xml
