找不到用于休眠配置的类？

Question

我正在使用Intellij，Maven，Tomcat，Hibernate和JEE创建一些应用程序。 当我尝试通过Tomcat通过Intellij运行我的应用程序时，webrowser中出现错误：

我的项目结构如下：

当我运行JUnit测试时，所有功能都可以正常工作。

import com.advertisement.entity.Advertisement;
import com.advertisement.entity.AppUser;
import junit.framework.TestCase;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;

/**
 * Unit test for simple App.
 */
public class AppTest extends TestCase {

    public void testAppUser() {
        SessionFactory sessionFactory = new Configuration().configure()
                .buildSessionFactory();
        Session session = sessionFactory.openSession();
        session.beginTransaction();

        AppUser user = new AppUser("firstuser");
        session.save(user);

        session.getTransaction().commit();
        session.close();
    }

    public void testAppAdvertisement() {
        SessionFactory sessionFactory = new Configuration().configure()
                .buildSessionFactory();
        Session session = sessionFactory.openSession();
        session.beginTransaction();

        Advertisement advertisement = new Advertisement();
        session.save(advertisement);

        session.getTransaction().commit();
        session.close();
    }
}

问题是当我将其部署到Tomcat并在运行之后。在我看来，Tomcat没有看到Hibernate或Hibernate的配置，某些Hibernate配置路径不正确？
