Hibernate Enversを使用して、特定の日付にエンティティおよび関連するエンティティから完全なデータを取得しています。問題は、その瞬間に削除されたコレクションからアイテムにアクセスするときにエラーが発生することです。 これは、もう存在しないエンティティを取得するためにDBにアクセスしているために問題があるようです。エンベロープ：削除されたエンティティを含むコレクションのマッピングエラー
これがメインの実体である：

これは、我々がenversからデータを取得するために使用したコードです：
public PayrollEntity findHistorical(String idPayroll, DateTime date) {
AuditReader reader = AuditReaderFactory.get(getEntityManager());
return reader.find(PayrollEntity.class, idPayroll, (int)
reader.createQuery()
.forRevisionsOfEntity(PayrollEntity.class, false, true)
.add(AuditEntity.revisionProperty("revTimestamp").lt(date.getMillis()))
.addProjection(AuditEntity.revisionNumber().max())
.add(AuditEntity.id().eq(idPayroll))
.getSingleResult());
}
その後、我々はドーザを使用してDTOにデータをマップしようと、
Caused by: javax.persistence.EntityNotFoundException: Unable to find es.gc.epsilon.core.domain.SalaryItemEntity with id 15
at org.hibernate.ejb.Ejb3Configuration$Ejb3EntityNotFoundDelegate.handleEntityNotFound(Ejb3Configuration.java:157) [hibernate-entitymanager-4.2.14.SP1-redhat-1.jar:4.2.14.SP1-redhat-1]

私が言ったように、それはドーザーがペイロから削除されたアイテムにアクセスしたためですllSalaryItems collectionメインエンティティからのリスト。
ですから、質問はです。コレクション内の削除された項目を含むエンティティからのデータを、DTOにマップすることは可能ですか？私たちは正しい方法でやっていますか？
PD：私たちは事前にHibernateのバージョン4.2.21.Final
感謝を使用しています。
Answer @narosありがとうございます、私はそれがすでに4.2.21.Finalのバージョンで修正されているこのバグhttps://hibernate.atlassian.net/browse/HHH-5845だと思った。 解決策をリリースするまでは何か回避策がありますか？ – jeyViso
