java.lang.NoClassDefFoundError : org/hibernate/cfg/AnnotationConfiguration 错误

Question

我已经创建了一个网络动态项目，并且想使用 Hibernate与它。

然后，我使用了 Hibernate Code Generation生成类代码，我创建了一个类 HibernateUtil我在哪里初始化 SessionFactory .

public class HibernateUtil {
    private static final SessionFactory sessionFactory = buildSessionFactory();
    
    private static SessionFactory buildSessionFactory(){
        try{
            SessionFactory sessionFactory = 
                    new AnnotationConfiguration().configure().buildSessionFactory();
            return sessionFactory;
        }catch(Exception ex){
            ex.printStackTrace();
            throw new ExceptionInInitializerError(ex);
        }
    }
    
    public static SessionFactory getSessionFactory() {
        return sessionFactory;
    }
    
    public static void shutdown() {
        getSessionFactory().close();
    }
}

还有一个类HibernateSessionFactoryListener :

public class HibernateSessionFactoryListener implements ServletContextListener{

    @Override
    public void contextInitialized(ServletContextEvent arg0) {
        Session session = HibernateUtil.getSessionFactory().openSession();
        System.out.println("\n Context Initilaise \n");
    }

    @Override
    public void contextDestroyed(ServletContextEvent arg0) {
        HibernateUtil.shutdown();
        System.out.println("\n Context Detruit \n");
    }

}

当我运行我的项目时，我收到此错误消息:

我该如何解决这个问题？

这是我的 Java 构建路径:

在 Hibernate 3.6 中，“org.hibernate.cfg.AnnotationConfiguration”已被弃用，其所有功能已移至“org.hibernate.cfg.Configuration”。因此，您可以安全地将“AnnotationConfiguration”替换为“Configuration”类
