删除查询的 Hibernate 版本更新后出现子树意外结束异常

当我从表中删除所有数据时，出现奇怪的异常。自从我将 Hibernate 版本从 3.x.x 更新到 4.2.6 后，就出现了异常。

我调用从表中删除数据的 Dao 方法：

  @Override
  public void deleteAll()
  {
     EntityManager em = getEntityManager();
     em.createQuery( "DELETE Document" ).executeUpdate();
  }

Entity:

@Entity
@Table( name = "document" )
public class Document implements Serializable
{
  @Override
  @Id
  @GeneratedValue( strategy = GenerationType.IDENTITY )
  @Column( name = "document_id" )
  private int           id;

  private String                 filename;

  @Temporal( TemporalType.TIMESTAMP )
  @Column( name = "file_modified_time" )
  private Date                   fileModifiedTime;

  @ManyToOne( fetch = FetchType.LAZY )
  @JoinColumn( name = "attached_to_Task_fk" )
  private Task       attachedToTaskFk;

 //Getter/Setter
}

当我向删除查询添加 where 子句时，不会发生异常。

em.createQuery( "DELETE Document d WHERE d.id > 0" ).executeUpdate();

但我不认为 Hibernate 是这样想的。

我已经检查了以下主题：

• 子树意外结束 https://stackoverflow.com/questions/2066361/hibernate-and-unexpected-end-of-subtree-exception
• Hibernate 和子树意外结束异常 https://stackoverflow.com/questions/2066361/hibernate-and-unexpected-end-of-subtree-exception

有谁知道如何解决这个问题？

这似乎是一个休眠错误 https://hibernate.atlassian.net/browse/HHH-8578该问题已在 4.2.7 和 4.3.0.Beta5 中修复。 DeleteExecutor 以前需要一个Where 子句。

您可以找到patch https://github.com/hibernate/hibernate-orm/commit/e3419f6d722a276fd846178ee59b3176a9fb0da7如果您尚未准备好升级到 4.2.7，请访问 GitHub。
