Impossible d'ouvrir la session Hibernate pour la transaction: org.hibernate.exception.GenericJDBCException

Question

J'ai un projet printanier où pour cela j'utilise mysql comme base de données. J'ai configuré le pool de connexion Tomcat JDBC dans le fichier de configuration servelet et la connexion est fonctionnant bien dans ma machine locale. Mais récemment j'ai recréé notre serveur à distance et là suis après l'erreur ci-dessous quand j'essaye d'accéder à la base de données.

{"error":"unauthorized","error_description":"Could not open Hibernate Session for transaction; nested exception is org.hibernate.exception.GenericJDBCException: Could not open connection"}curl: (6) Could not resolve host: application 

Alors quelle sera la raison de ce même projet erreur.Dispositif ont pas de problèmes plus tôt et la question vient après recréer le server.I peut accéder à la base de données du serveur MySQL distant de phpMyAdmin en utilisant le même nom d'utilisateur et mot de passe. Aussi pas de problème lorsque nous exécutons le projet dans la machine locale et dans la base de données mysql locale. Voici mon fichier de configuration de servlet de printemps.

Voici comment j'utilise la session dans ma classe de service:

@Repository 
@Transactional 
public class MyMainService implements MainDao { 
    @Autowired 
    private SessionFactory sessionFactory; 

    private org.hibernate.Session getCurrentSession(){ 
     return sessionFactory.getCurrentSession(); 
    } 

    // just a sample 
    @Override 
    public void setUser(String idStr, Integer age) { 
     UserSample newUserSam = new UserSample(); 
     try{ 
      newUserSam.setAge(age); 
      newUserSam.setId(idStr); 
      getCurrentSession().saveOrUpdate(newUserSam); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 

}
