java.lang.NoClassDefFoundError：org / hibernate / cfg / Anno

然后,我使用Hibernate代码生成来生成类代码,并创建了一个HibernateUtil类,我在其中初始化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();
    }
}

另一个类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：

我怎么解决这个问题 ？

这是我的Java构建路径：
