Question

您好我试着找到我的问题的答案，但第二天没有成功:)所以我决定在这里写我的帖子。所以我使用Hibernate envers并通过他的Id获取当前实体的所有修订版。然后我想得到这个实体的所有改变道具并创建新实体，其中包含更改oldValue newValue的更改日期。几天前我的项目工作正常后，它不是:)。所以这是图片：这是我的功能，返回结果。

@Override
public List<List<Object[]>> getAuditForPelaltyProtocolItem(int id) {
    List<List<Object[]>> auditResultList = new ArrayList<>();
    AuditReader reader = AuditReaderFactory.get(getSession());
    AuditQuery query = reader.createQuery().forRevisionsOfEntity(PenaltyProtocolItem.class, false, true)
            .add(AuditEntity.id().eq(id)).
            add(AuditEntity.property("changed").eq(false)); 
    auditResultList.add(query.getResultList());

    AuditQuery queryTwo = reader.createQuery().forRevisionsOfEntity(PenaltyProtocolItem.class, false, true)
            .add(AuditEntity.id().eq(id)).
            add(AuditEntity.property("changed").eq(true));
    auditResultList.add(queryTwo.getResultList());
    return auditResultList;

}

这是我的PenaltyProtocolItem类：

@Audited
public class PenaltyProtocolItem implements Serializable, Comparable<PenaltyProtocolItem>{

private int version;

private static final long serialVersionUID = 2271491886865089185L;

private int id = -1;
private PenaltyProtocol protocol = null;
private RepatriateVehicle repatriateVehicle = null;
private Parking parking = null;
private Violation violation = null;
private PenaltyVehicleTax tax = null;
private Employee createdBy = null;
private Employee modifiedBy = null;
private String remark = null;
private Time rowTime = null;
private String street = null;
private ParkingZoneTypes zone = null;
private Timestamp modifiedTime = null;
private boolean isChanged = false;
}

我的另一个带有envers注释的课程

@Audited
public class RepatriateVehicle implements Serializable{

private int version;

private static final long serialVersionUID = 84210604965295166L;

private int id = -1;
private VehicleType vehicleType = null;
private VehicleStatus vehicleStatus = null;
private Employee createdBy = null;
private Employee modifiedBy = null;
private String regNum = null;
private VehicleMake make = null;
private String model = null;
private String color = null;
private Timestamp modifiedTime = null;
}

我是否需要使用@Audited on my entity (VehicleType, VehicleStatus,Employee, VehicleMake)或我需要使用@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)。当我不更改它时，我只需将其替换为新实体，因此我不需要审计表来进行此更改。当我在审计表中更改PenaltyProtocolItem时，PenaltyProtocolItem包含我所做的所有更改，但是当我得到结果时，我的RepatriateVehicle所有属性都为null，而且几天前当我使用相同的函数时，所有道具都是来自RepatriateVechicle审计表的值，但没有现在。从那以后我改变了唯一的东西我将注释从@Audit更改为@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)但是我不知道我改变了哪一个，现在我很伤心:)。这是我的审计表的图片： enter image description here enter image description here

当我尝试获取((PenaltyProtocolItem)nextObj[0]).getRepatriateVehicle().getMake()时，我收到错误org.hibernate.ObjectNotFoundException: No row with the given identifier exists可能是因为它在审核表中查找了这样的行，但是需要从公共模式中获取它。如果有人可以帮助我，我会节省更多的时间:)。感谢

我无法相信我找到了它。所以让我们花一些时间来搜索其他人。我的问题是什么：注释。所以我有一个实体 PenaltyProtocolItem具有一些不需要审核的属性，但是当我将其替换为其他时，我需要保存此实体的不同ID，因此我需要@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)而非@Audit，因为@Audit希望我注释PenaltyProtocolItem的所有实体道具。与RepatriateVehicle一样，它需要@Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)。我希望这对某些人有用，因为我真的失去了大约2天才能找到它。但这是我第一次接触技术，所以可能是正常的:)。
