java - org.hibernate.QueryException : could not resolve property: createdDate_MOD of: org. baeldung.HibernateAuditDemo.model.Order_AUD

Question

我使用 hibernate envers 进行审计。

我有简单的Order实体:

@Entity
@Table(name = "orders")
@Audited
public class Order {

    @Id
    @GeneratedValue(generator = "increment")
    @GenericGenerator(name = "increment", strategy = "increment")
    private Long id;

    private Double price;

    @Temporal(TemporalType.TIMESTAMP)
    private Calendar createdDate;

    public Order() {
    }
    //the rest is unimportant

我使用 AuditorReader查询属性已更改的修订:

    AuditReader auditReader = AuditReaderFactory.get(entityManager);
            // find revision at which order entity changed its property createdDate
            List revisions = auditReader.createQuery().forRevisionsOfEntity(Order.class, false, true).
            add(AuditEntity.property("createdDate").hasChanged()).getResultList();

            Object[] history = (Object[]) revisions.get(0);

在这段代码中我得到异常:

org.hibernate.QueryException: could not resolve property: createdDate_MOD of: org.baeldung.HibernateAuditDemo.model.Order_AUD [select e__, r from org.baeldung.HibernateAuditDemo.model.Order_AUD e__, org.hibernate.envers.DefaultRevisionEntity r where e__.createdDate_MOD = :_p0 and e__.originalId.REV.id = r.id order by e__.originalId.REV.id asc]
        at org.hibernate.persister.entity.AbstractPropertyMapping.propertyException(AbstractPropertyMapping.java:83)
        at org.hibernate.persister.entity.AbstractPropertyMapping.toType(AbstractPropertyMapping.java:77)
        at org.hibernate.persister.entity.AbstractEntityPersister.toType(AbstractEntityPersister.java:1967)

在表中的数据库中orders和 orders_aud ，我看到名为 createdDate 的列但不是 createdDate_MOD .

为什么不能属性createdDate解决了吗？

要让 hibernate envers 跟踪对某些属性的更改，您需要在该属性上设置 @Audited(withModifiedFlag = true)。

要为所有实体全局设置它，您需要在 hibernate 属性中将 org.hibernate.envers.global_with_modified_flag 设置为 true。
