首次休眠 - 运行时出错

Question

这是我的代码：

import java.util.List;
import org.hibernate.Criteria;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;
public class Test {
  public static void main(String[] args) {
    Configuration config = new Configuration();
    config.configure("/com/azienda/progettoCorso/Hibernate/mode/hbm
        /hibernate.cfg.xml");                 
    SessionFactory sessionFactory = config.buildSessionFactory();
    Session session = sessionFactory.openSession();
    Transaction trans = session.beginTransaction();
    //ISTRUZIONI SQL
    Criteria criteria = session.createCriteria(Aula.class);
    List<Aula> list = criteria.list();
    trans.commit();
    session.getSessionFactory().close();
  }
}

我在运行时收到此错误，我不知道如何解决。你可以帮我吗？

这是我的配置文件

是配置问题吗？我需要一些帮助，因为我是冬眠新手，不知道我到底在做什么。如果我的 cfg 上有一些错误，我看不到它们。

感谢您的帮助

从我所看到的情况来看，它似乎缺少休眠.cfg文件或格式不正确。你为什么不从互联网上拿一个示例项目来理解然后结构。
