我有以下结构:

@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...
}

在数据库中,我有 2 个表:C_MEETING 和 C_ACCREDITATION,它们都包含 TEMPORARY_CONTAINER_ID 作为 PK。

当我尝试查询时:

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

我看到了正确的结果query.getResultSize()

但是当我尝试用query.list()

我收到此错误:

添加@MappedSuperclass到您的 TemporaryContainerTO 类。我认为您可以从中删除@Entity和删除@Inhertitance
