Java Hibernate-加载时需要使用unions策略-id加载的每个子类的表

我的结构如下：

@Entity
@Inheritance(strategy = InheritanceType.TABLE_PER_CLASS)
public abstract class TemporaryContainerTO {
   protected Long temporaryContainerId;

   @Id
   @GeneratedValue(strategy = GenerationType.TABLE)
   @Column(name = "TEMPORARY_CONTAINER_ID", unique = true, nullable = false)
   public Long getTemporaryContainerId() {
      return temporaryContainerId;
   }

   public void setTemporaryContainerId(Long temporaryContainerId) {
      this.temporaryContainerId = temporaryContainerId;
   }
}

@Entity
@Table(name = "C_MEETING", catalog = "dbo")
public class MeetingTO extends TemporaryContainerTO {
   other properties....
}

@Entity
@Table(name = "C_ACCREDITATION", catalog = "dbo")
public class AccreditationTO extends TemporaryContainerTO {
   other properties...
}

在db中，我有两个表：C_会议和C_认证，都包含作为PK的临时容器ID

当我尝试查询时：

// fetch options
Criteria criteria = fullTextSession.createCriteria(TemporaryContainerTO.class);
criteria.setFetchMode("country", FetchMode.JOIN);
query.setCriteriaQuery(criteria);

我看到了

query.getResultSize（）的正确结果

但是当我尝试使用
query.list（）获取对象时

我收到这个错误：
