Не удалось открыть сеанс Hibernate для транзакции: org.hibernate.exception.GenericJDBCException

Question

У меня есть проект Spring, где для этого я использую mysql в качестве базы данных. Я сконфигурировал пул соединений Tomcat JDBC в файле конфигурации приложения, и соединение отлично работает на моей локальной машине. Но в последнее время я воссоздал наш удаленный сервер и там, после того как я получил ошибку ниже, когда пытаюсь получить доступ к базе данных.

{"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 

Так что будет причиной для этого error.The же проект имеет никаких проблем раньше, и этот вопрос приходит после воссоздания server.I может получить доступ к базе данных MySQL удаленного сервера из PHPMyAdmin используя имя пользователя и пароль. Также не проблема, когда мы запускаем проект в локальной машине и локальной базе данных mysql. Ниже приведен файл конфигурации моего сервлета.

Это, как я использую сессии в своем классе услуги:

@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(); 
     } 
    } 

}

Это мой pom.xml, который хорошо работает с JBoss. Просто убедитесь, что у вас есть дополнительные . Ограничения зависимостей HIBERNATE остаются неизменными.
