java使用Hibernate envers时，什么可能导致奇怪的属性解析错误？

Question

是什么原因导致hibernate尝试解析包路径，并且在执行此操作时失败：

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]

我正在使用hibernate 3.6.9

在我为两个被审计实体之间的许多关系引入审计之前，一切都是正常的。基本上是公路。爪哇：

@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，结果成功了。我真的很感激任何帮助或朝着正确的方向推动。如果需要其他信息，请说出它的名字，我可以提供

回答我自己的问题：

该漏洞是3.6版本的hibernate envers的问题，在某些情况下，它会遇到来自爱沙尼亚域名（例如ee.codeto.foo）的包名问题。这是因为hibernate envers在构建查询时的某个时刻使用了“ee”作为别名，如果使用了包的完整类名（现在总是这样），那么hibernate认为包名中“ee”之后的下一部分是列名

在hibernate的更高版本中，这个问题得到了解决。可能不是因为爱沙尼亚的域名，而是因为更好的别名使用。使用“ee_em>”代替“ee”。因此，当你可能很不幸地拥有一个包，包名的第一部分是“ee389;”，并且碰巧使用了hibernate envers，碰巧使用了多对多映射，碰巧遇到了不幸的情况，hibernet试图在包中使用完整的类名，那么你可能会受到影响这个虫子
