How not to audit a join table and related entities using Hibernate Envers?
提问by Romain Linsolas
I use Hibernate Envers to audit my entities.
我使用 Hibernate Envers 来审计我的实体。
I have one audited entity, Foo, which has a List<Bar>as properties. However, I don't want to audit the Barentities. Thus, I wrote that:
我有一个经过审计的实体 ，Foo它有一个List<Bar>as 属性。但是，我不想审计Bar实体。因此，我写道：
@Entity
@Audited
public class Foo {
@JoinTable(name = "T_FOO_BAR", joinColumns = @JoinColumn(name = "FOO_ID"), inverseJoinColumns = @JoinColumn(name = "BAR_ID"))
@ManyToMany(cascade = PERSIST)
@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)
public List<Bar> getBars() {
return bars;
}
}
Now, I want to retrieve a revision of Foo:
现在，我想检索以下版本Foo：
AuditReader reader = AuditReaderFactory.get(getEntityManager());
Foo revision = (Foo) reader.createQuery().forEntitiesAtRevision(Foo.class, 42).getSingleResult();
Unfortunately, when I want to retrieve all the data (i.e. when it lazy loads the bars), I get the error ORA-00942: table or view does not exist, as it tried to query:
不幸的是，当我想检索所有数据时（即当它延迟加载时bars），我收到错误ORA-00942: table or view does not exist，因为它试图查询：
select ... from T_FOO_BAR_AUD x, T_BAR y where ...
I though that using @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED), Hibernate Envers would keep the links with the Baritems of the currententity.
我虽然使用@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)，Hibernate Envers 会保持与当前实体的Bar项目的链接。
So how can I solve my problem, without having to explicitely audit the tables T_BARand T_FOO_BAR(the join table)? In others words, when I retrieve the list of barsfrom my revision entity, I get the list of barsfrom my current entity (as the links between Fooand Barare not audited).
那么如何解决我的问题，而不必明确地审计表T_BAR和T_FOO_BAR（连接表）？在别人的话，当我检索列表bars从我的修订实体，我得到的名单bars，从我目前的实体（如之间的联系Foo，并Bar未经审计）。
Thanks.
谢谢。

It looks like you're using @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)when you should be using @NotAuditedin your case.
看起来您在@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)应该@NotAudited在您的情况下使用时正在使用。
RelationTargetAuditMode.NOT_AUDITEDwill simply not audit the target entity. It will still try to audit the List<Bar>property of Foo, and thus the join table.
RelationTargetAuditMode.NOT_AUDITED不会审计目标实体。它仍然会尝试审计 的List<Bar>属性Foo，从而审计连接表。
From the docs:
从文档：
If you want to audit a relation, where the target entity is not audited (that is the case for example with dictionary-like entities, which don't change and don't have to be audited), just annotate it with
@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED). Then, when reading historic versions of your entity, the relation will always point to the "current" related entity.
如果你想审计一个关系，其中目标实体没有被审计（例如类似字典的实体就是这种情况，它不会改变也不必被审计），只需用
@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED). 然后，在读取实体的历史版本时，该关系将始终指向“当前”相关实体。
