我在尝试让经审计的实体引用未经审计的实体时遇到问题。在我们的应用程序中，某些实体是在不使用休眠的情况下引导的，这些实体是我们的元模型，不需要审计。
工作示例：
public class A {
private String id;
private List<B> attributeReferences;
}
public class B {
private String id;
private A attributeReference;
}
如果我执行代码：
A rev1 = getAuditReader().find(A.class, "foo", 1);
A rev2 = getAuditReader().find(A.class, "foo", 2);
A rev3 = getAuditReader().find(A.class, "foo", 3);
一切顺利，但是如果我尝试获取 B 的版本，则会发生错误：
B rev2 = getAuditReader().find(B.class, "bar", 2);
org.hibernate.ObjectNotFoundException：不存在具有给定标识符的行 [metafoo]
Envers 通过对我的 metafoo 实体的惰性引用成功地查找了 B 实体。但是，当尝试将其存储在其缓存中时，我的 B 实体的 hashcode 方法被调用，这反过来会查找审计表中不存在的 metafoo，从而引发异常。
有没有办法可以忽略那些不存在的引用而不是抛出这个错误？（也许通过在查询中排除此类引用）
如何完全处理不存在的数据（假设我们从审计表中删除了所有超过 1 个月的条目）我们如何仍然查询引用不存在的实体？
PS：
如果可能，我不想修改哈希码函数
我不想审核我的元模型
表结构：
表一：
ID
----------------------------------------
metaFooAttribute
fooAttribute
foo
表 A_AUD：
REV REVTYPE ID
----------------------------------------
1 0 fooAttribute
1 0 foo
2 1 foo
3 1 foo
表 B：
ID
----------------------------------------
bar
表 B_AUD：
REV REVTYPE ID ATTRIBUTE_ID
----------------------------------------
1 0 bar metaFooAttribute
1 0 bar fooAttribute
2 1 bar fooAttribute

编辑：
我发现这篇文章很有趣，但它并没有解决问题，因为我的参考是 A 类型，所以注释 @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED) 不起作用。
