我们正在使用Envers审核表。我们正在使用Envers的AuditReader获得更改的历史记录。
数据已正确存储在数据库（表和审计表）中。
我们这样检索审核数据
public List<D> findAlleHistoriek(@Nonnull String erkenningsDossierId) {
List<D> erkenningsDossiers = new ArrayList<>();
List<Number> revisionNumbers = auditReader.getRevisions(ErkenningsDossier.class, erkenningsDossierId);
for (Number rev : revisionNumbers) {
// -- exception occurs here:
ErkenningsDossier dossier = auditReader.find(ErkenningsDossier.class, erkenningsDossierId, rev);
// --
erkenningsDossiers.add((D) dossier);
}
return erkenningsDossiers;
}
然后我们得到这个异常：
org.hibernate.HibernateException: HHH000143: Bytecode enhancement failed because no public, protected or package-private default constructor was found for entity:
be.vaph.sparta.services.actoren.maatschappelijkerol.erkendemaatschappelijkerol.ErkendeMaatschappelijkeRol. Private constructors don't work with runtime proxies!
知道我们在做什么错吗？
我相信，这些是我们数据模型中最相关的部分：

// ...
