在使用Hibernate启用程序时，什么会导致奇怪的属性解析错误？

Question

是什么原因导致hibernate试图解析包路径，同时也会失败：

Exception in thread "Timer-9" org.hibernate.QueryException: could not resolve property: codeto of: citylist_AUD [select new list(ee, e) from citylist_AUD ee, ee.codeto.wes.Citylist_AUD e where ee.originalId.citylist_id = e.originalId.id and ee.originalId.Road_id = :Road_id and e.originalId.REV.id = (select max(e2.originalId.REV.id) from ee.codeto.wes.Citylist_AUD e2 where e2.originalId.REV.id <= :revision and e.originalId.id = e2.originalId.id) and ee.originalId.REV.id = (select max(ee2.originalId.REV.id) from road_city_AUD ee2 where ee2.originalId.REV.id <= :revision and ee.originalId.Road_id = ee2.originalId.Road_id and ee.originalId.citylist_id = ee2.originalId.citylist_id) and ee.REVTYPE != :delrevisiontype and e.REVTYPE != :delrevisiontype]

我使用hibernate 3.6.9

在我引入两个已审计实体之间的ManyToMany关系审计之前，一切都很顺利。基本上是Road.java：

@Audited
@Entity
@Table(name = "ROAD")
@Cache(usage = CacheConcurrencyStrategy.READ_WRITE)
public class Road {
    ...
    @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)
    @ManyToMany(fetch = FetchType.LAZY)
    @JoinTable(name = "ROAD_CITYLIST", joinColumns = { @JoinColumn(name = "ROAD_ID") }, inverseJoinColumns = { @JoinColumn(name = "CITYLIST_ID") })
    @Fetch(FetchMode.SUBSELECT)
    @Cache(usage = CacheConcurrencyStrategy.NONE)
    private Set<CityList> citylists;
    ...
}

我用同样的逻辑做了一个类似的小测试，并取得了成功。我真的很感激你给予我任何帮助或者推动它朝着正确的方向前进。如果需要更多的信息，只需命名它，我可以提供。

回答我自己的问题：

该漏洞是使用hibernate envers的3.6，在某些情况下，从爱沙尼亚域名派生的包名(例如ee.codeto.foo)遇到了麻烦。这是因为hibernate在构建查询时使用了"ee“作为别名，如果使用了包的完整类名(现在总是这样)，hibernate认为包名后面的下一部分是列名。

在hibernate的后期版本中，这个问题得到了解决。可能不是因为这是爱沙尼亚的域名，而是因为更好的别名使用。用"ee_“代替"ee”。因此，当您可能有一个以"ee_“作为包名的第一部分的包时，碰巧使用hibernate envers，并且碰巧使用了多到多的映射，并且碰巧有hibernet试图在包中使用完整类名的不幸情况，那么您可能受到此bug的影响非常小。
