我正在使用 hibernate envers 5.2.17.Final 版本来存储和检索实体的审计历史记录，并在检索Category实体的审计历史记录时出现以下异常。

这是我的Category实体的样子。如您所见，NCRRule 使用NAME而不是主键Id映射到 Category 。

@Data
@Entity
@Table(name = TableNames.CATEGORY)
@Audited
@AuditTable(value = TableNames.CATEGORY_HISTORY)
public class Category {

    @Id
    @Column(name = "ID")
    @GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "categoryGenerator")
    @SequenceGenerator(name = "categoryGenerator", sequenceName = "GENERAL_CATEGORY_SQ", allocationSize = 1)
    private long id;

    @ManyToOne
    @JoinColumn(name = "NCR_RULE", insertable = false, updatable = false, referencedColumnName = "NAME")
    @Getter(onMethod = @__({@JsonIgnore, @Transient}))
    @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED)
    private NCRRule ncrRule;
}

NCRRule是未经审计的实体

@Entity
@Table(name= TableNames.NCR_RULE)
public class NCRRule implements Serializable {

    @Id
    @Column(name = "ID")
    private Long id;

    @Column(name = "NAME", unique = true)
    private String ncrRuleName;

    public Long getId() {
        return id;
    }

    public String getNcrRuleName() {
        return ncrRuleName;
    }
}

异常堆栈跟踪如下：

我尝试将in设置@AuditMappedBy(mappedBy = "ncrRuleName")为实体，但在启动时出现异常。private NCRRule ncrRule;Category

Caused by: org.hibernate.MappingException: @AuditMappedBy points to a property that doesn't exist: NCRRule.ncrRuleName

检索审计历史的代码是：

        AuditQuery auditQuery = auditReader.createQuery()
            .forRevisionsOfEntity(Category.class, false, true)
            .add(AuditEntity.id().eq(entityId))
            .addOrder(AuditEntity.revisionProperty("timestamp").asc());

        List<AuditQueryResult<Category>> auditQueryResults = AuditQueryUtils.getAuditQueryResults(auditQuery, Category.class);
