我有一個實體，我想跟蹤所有更改，因此我創建了新的實體進行審計。 下面是我的主要實體：休眠 - 實體審計
@Data
@NoArgsConstructor
@AllArgsConstructor
@Entity
@EntityListeners(AuditingEntityListener.class)
@Table(name = "primary")
public class PrimaryEntity {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "primary_id")
private Long id;
private String name;
@LazyCollection(LazyCollectionOption.FALSE)
@ElementCollection
@CollectionTable(
name = "primary_attachments",
joinColumns = @JoinColumn(name = "primary_id")
)
private List<String> attachments;
@CreatedDate
@Temporal(TemporalType.DATE)
private Date createDate;
@LastModifiedDate
@Temporal(TemporalType.DATE)
private Date lastModifiedDate;
}
而且下面是我對審計實體：
@Data
@NoArgsConstructor
@AllArgsConstructor
@Entity
@EntityListeners(AuditingEntityListener.class)
@Table(name = "primary_audit")
public class PrimaryEntityAudit {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Column(name = "audit_id")
private Long id;
@NotNull
@Column(name = "primary_entity_id")
private Long primaryId;
private String name;
@LazyCollection(LazyCollectionOption.FALSE)
@ElementCollection
@CollectionTable(
name = "primary_attachments_audit",
joinColumns = @JoinColumn(name = "primary_entity_id")
)
private List<String> attachments = new ArrayList<>();
@CreatedDate
@Temporal(TemporalType.DATE)
private Date createDate;
public PrimaryEntityAudit(PrimaryEntity primaryEntity) {
this.primaryId = primaryEntity.getId();
this.attachments.addAll(primaryEntity.getAttachments());
this.createDate = new Date();
}
}
我創造新的PrimaryEntityAudit並保存此對象，然後更新主實體之前更新的主要實體。 操作成功並保存了對象PrimaryEntityAudit，但不保存PrimaryEntityAudit的附件。
我也嘗試過在ProjectEntityAudit的構造函數中執行setAttachments，但後來我得到一個異常：HibernateExcpetion：找到對集合的共享引用。
我應該如何映射審計集合以保存PrimaryEntity附件的舊狀態？
