Java 无法创建请求的服务[org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]？

我使用的是SQLite和Hibernate ORM core版本5.4.20.Final，但出现以下错误

最后，我有一个课程，负责坚持

import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.hibernate.cfg.Configuration;

import com.abigsite.facturationsystem.model.Role;

public class Example {
    public static void main(String[] args) {
        SessionFactory session = new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();
        Session s = session.openSession();

        Transaction t = s.beginTransaction();

        Role role = new Role();
        s.save(role);
        t.commit();
    }
}

错误发生在以下行：

SessionFactory session = new Configuration().configure("hibernate.cfg.xml").buildSessionFactory();

验证数据库的位置，此外，依赖项中使用了SQLite JDBC.jar，另一方面，使用了正确的方言，与库相同

您可能用错误的标记标记了这个问题。您的代码正在使用Hibernate，而不是NHibernate:-）已编辑，很抱歉我没有意识到。您可能用错误的标记标记了此问题。您的代码正在使用Hibernate，而不是NHibernate:-）编辑，很抱歉我没有意识到。
