Question

我在netbeans中创建了一个java应用程序，它读取csv文件并使用hibernate ORM将数据插入SQL DB。 Java应用程序运行正常，并在我从IDE运行应用程序时将记录插入到数据库中。但是如果我将项目编译成JAR文件并在命令提示符下运行它，那么我会收到以下错误。任何帮助都非常感谢，因为我是Java的新手，我无法弄清楚导致问题的原因。

这是会话的代码

    SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
    Session session = sessionFactory.openSession();

这是从命令提示符

运行时获得的异常

我想出了这个问题，我签署了jar文件并从命令提示符执行它，这导致了问题。如果我在没有签名的情况下运行jar文件，它运行正常！
