我需要通过EmbeddedId的属性进行修改。但我不知道如何。
@Entity
@javax.persistence.Table(name = "orders_details")
@Audited
public class OrderDetail implements Serializable {
@EmbeddedId
private OrderDetailsId id;
@Embeddable
public class OrderDetailsId implements Serializable {
@Basic
@Column(name = "product_name")
private String prodName;
@Basic
@ManyToOne
@JoinColumn(name = "order_id")
private Order order;
AuditReader auditReader = AuditReaderFactory.get(em);
List list = auditReader.createQuery().forRevisionsOfEntity(Order.class, false, false).
add(AuditEntity.property("id.order").eq(id)).getResultList();
GetResultList抛出NullPointer（。 我怎么能这样做？
好的）这里Stack Trace

答案 0 :(得分：1)
您正在获取NullPointerException，因为您要求Envers查询API查找Order实体的修订版本，您未将其指定为已审核。
我已经提交了一个JIRA问题HHH-11558来解决这个问题，并提出了更为积极的回应。
如果Order已经审核了，它就会按预期运作。
