Envers：錯誤映射具有已刪除實體的集合

我們使用Hibernate Envers從特定日期的實體及其相關實體獲取完整數據。問題在於，在訪問集合中的項目時發生錯誤，該集合在該時刻之後被刪除。所以看來問題是因爲訪問數據庫來檢索不存在的實體。Envers：錯誤映射具有已刪除實體的集合

這是主要的實體：

    public void setYear(int year) {

    }

這是我們用來從envers獲取數據的代碼：

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()); 
    }

然後，我們嘗試用推土機將數據的DTO映射，我們得到這個錯誤：

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]

正如我所說，這似乎是因爲推土機訪問從payro刪除的項目llSalaryItems集合來自主實體的列表。

所以，問題是。有可能將實體中的數據映射到集合中的已刪除項目到DTO中？我們正在做正確的方式嗎？

PD：我們正在使用Hibernate的版本4.2.21.Final

在此先感謝。

您所描述的是由HHH-8093和HHH-8051標識的問題，這兩個問題都暫定爲Hibernate Envers 6.0版本。

如果我在6.0版本之前找到這些，我會嘗試。

很明顯，這並不能解決您對Hibernate Envers 4.2的迫切需求，而這種需求很古老，不再維護或修補。

謝謝你的回答@naros，我以爲是這個錯誤https://hibernate.atlassian.net/browse/HHH-5845它已經修復了4.2.21.Final版本。有什麼解決方法可以嘗試，直到您發佈解決方案？ – jeyViso
