修复我的previous issue 后，我又遇到了一些麻烦。我尝试了许多常见的修复程序，但似乎没有一个对我有用。以下是我项目中的相关文件：

我一直在设置 Hibernate 一段时间，感谢任何帮助。

    【解决方案1】：

    修好了！我在使用 Hibernate 访问数据库的 bean 中构建 SessionFactory 时使用了 addAnnotatedClass() 方法。完整代码如下：

    AccountAccessBean.java

    @Stateless(mappedName = "AccountAccessBean")
@LocalBean
public class AccountAccessBean {
    public void resigterAccountEvent() {

        Configuration configuration = new Configuration().configure();
        ServiceRegistry registry = new StandardServiceRegistryBuilder()
                .applySettings(configuration.getProperties())
                .build();
        SessionFactory sessionFactory = configuration
                .addAnnotatedClass(Account.class)
                .addAnnotatedClass(Accountaccesslog.class)
                .buildSessionFactory(registry);
        Session session = sessionFactory.openSession();

        session.beginTransaction();
        Account accountEntity = (Account) session.get(Account.class, new Integer(1));
        System.out.println(accountEntity.getId());

    }
}
