Exécution d'une requête mysql en tant que requête native dans Hibernate

Question

Je suis nouveau sur Hibernate. Je crée une application web en utilisant JSF, Spring et Hibernate. Je suis en train de mettre en œuvre cette requête générée par le filtre utilisateur à l'aide mise en veille prolongée

select * from (Select DATE_FORMAT(a.call_offered_time,'%d %b %Y %k:%i:%s') As 'call_date', a.caller_id as 'Caller', DATE_FORMAT(a.call_offered_time,'%d %b %Y %k:%i:%s') as 'Call Connected', DATE_FORMAT(a.call_disconnect_time,'%d %b %Y %k:%i:%s') as 'Call Disconnected',a.channel_no as 'Channel', a.call_status as 'Call Status', (Case When a.call_routed_to_agent=Null or a.call_routed_to_agent='' then 'IVRS' Else call_routed_to_agent End) as 'Call Routed To', b.ddi,TIMESTAMPDIFF(SECOND,a.call_offered_time,a.call_disconnect_time) as 'Duration'from CallDetail a,ddi_details b Where a.call_reference_no =b.call_reference_no and a.call_offered_time Between '2006-01-01 00:00:00' And '2010-11-20 23:59:00') as t order by STR_TO_DATE(t.call_date,'%d %b %Y %k:%i:%s') 

Pour cela, j'ai essayé le code suivant

Session session = null; 
    // This step will read hibernate.cfg.xml and prepare hibernate for use 
    SessionFactory sessionFactory = this.getSessionFactory(); 

    session =sessionFactory.openSession(); 



    //Create Select Clause HQL 
    String SQL_QUERY ="select * from (Select DATE_FORMAT(a.call_offered_time,'%d %b %Y %k:%i:%s') As 'call_date', " + 
         "a.caller_id as 'Caller', DATE_FORMAT(a.call_offered_time,'%d %b %Y %k:%i:%s') as " + 
         "'Call Connected', DATE_FORMAT(a.call_disconnect_time,'%d %b %Y %k:%i:%s') as " + 
         "'Call Disconnected',a.channel_no as 'Channel', a.call_status as 'Call Status', " + 
         "(Case When a.call_routed_to_agent=Null or a.call_routed_to_agent='' then 'IVRS' " + 
         "Else call_routed_to_agent End) as 'Call Routed To', b.ddi," + 
         "TIMESTAMPDIFF(SECOND,a.call_offered_time,a.call_disconnect_time) as " + 
         "'Duration'from CallDetail a,iss_master.ddi_details b Where " + 
         "a.call_reference_no =b.call_reference_no and a.call_offered_time Between " + 
         "'2006-01-01 00:00:00' And '2010-11-20 23:59:00') as t order by STR_TO_DATE(t.call_date,'%d %b %Y %k:%i:%s')"; 

    System.out.println(SQL_QUERY); 

    Query query = session.createSQLQuery(SQL_QUERY).addEntity(InboundCallDetail.class); 

    List result = query.list(); 

Quand je lance ce code, je reçois l'erreur suivante

Veuillez corriger mon erreur ou suggérer d'autres moyens.

Merci à l'avance,

P.S Ceci est une application de rapport pour la condition « où » dans la requête est générée par l'utilisateur à travers le filtre.

Mise à jour Désolé d'être en retard! Depuis que je créé l'application à l'aide Spring Hibernate Je n'ai pas créé hibernate-config.xml au lieu que je fourni les détails dans l'application-context.xml

Mon mise à jour du code java est en fo llows

@PersistenceContext private EntityManager em; 
EntityManagerFactory emf = Persistence.createEntityManagerFactory("myapp"); 

em = emf.createEntityManager(); 
Query query = em.createNativeQuery(SQL_QUERY); 

Veuillez corriger mes problèmes. Merci pour les mises à jour !!

Mise à jour

J'ai essayé comme suggéré par @ckuetbach et j'ajouté

<value> 
     com/address/InboundCallDetail.hbm.xml 
    </value> 

dans le fichier application context.xml

Maintenant, je reçois cette erreur

Veuillez corriger mon erreur!

Answer 1

Si vous souhaitez exécuter la requête mysql requête native dans Hibernate vous pouvez utiliser createNativeQuery()

Answer 2

Je pense que vous avez manqué d'inclure une cartographie de vous entité. Vous devez créer et ajouter des fichiers de mappage pour toutes vos entités.

<property name="mappingResources"> 
    <list> 
     <value> 
      com/address/Address.hbm.xml 
     </value>     
     <value> 
      com/address/InboundCallDetail.hbm.xml 
     </value>  
    </list> 
</property> 

Le deuxième problème semble être que vous n'avez pas défini la mise en veille prolongée Dialect Hibernate Dialect must be explicitly
