トランザクション用のHibernateセッションを開くことができませんでした：org.hibernate.exception.GenericJDBCException

Question

私はデータベースとしてmysqlを使用しているところでspringプロジェクトを持っています。サーブレット設定ファイルにTomcat JDBC接続プールを設定しました。私のローカルマシンで正常に動作します。しかし、私はリモートサーバを再作成した後、データベースにアクセスしようとするとエラーが発生します。

{"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 

だから何がこのerror.The同じプロジェクトの理由になりますが、以前は問題がないと問題がserver.Iは、同じユーザー名とパスワードを使用してphpMyAdminのからリモートサーバのMySQLデータベースにアクセスすることができます再作成後に来ます。ローカルのマシンとローカルのmysqlデータベース内でプロジェクトを実行しても問題ありません。 以下は私の春のサーブレット設定ファイルです。

があなたのポンポンで、次の依存関係を追加します。

@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(); 
     } 
    } 

} 

はここに私のpom.xmlファイルである：私は私のサービス・クラスでセッションを使用していますどのようにこれは

私のpom.xmlはJBossでうまく動作します。HIBERNATE依存関係は同じままです。
