我对数据库执行许多请求时遇到错误。 当我在“应用程序”上的位置/按钮上多次单击时，出现错误。 一切正常，直到用户在应用程序中多次单击。
有人可以帮助我解决此错误吗？
我的persistence.xml：

这是我使用的实体类的示例：
@Entity
@Table(name = "primes", schema="public")
@Data
@NoArgsConstructor
@AllArgsConstructor
@EqualsAndHashCode(callSuper = true)
@ToString(callSuper = true)
public final class PrimeEntity extends PlanItemEntity {
@Builder(toBuilder = true)
public PrimeEntity(Long id,
String swpId,
String name,
String status,
String version,
Long itTarget,
Long bizTarget,
List<DomainEntity> domains,
String description,
String itOwner,
String bizOwner,
ZonedDateTime excelUpdate) {
super(id, swpId, name, status, version, itOwner, bizOwner);
this.itTarget = itTarget;
this.bizTarget = bizTarget;
this.domains = domains == null ? new LinkedList<>() : domains;
this.description = description;
this.excelUpdate = excelUpdate;
}
@Column(name = "it_target")
private Long itTarget;
@Column(name = "biz_target")
private Long bizTarget;
@Column(name="excel_update")
private ZonedDateTime excelUpdate;
@OneToMany(mappedBy = "prime", cascade = CascadeType.ALL, fetch = FetchType.LAZY)
@OrderBy("UPPER (name) ASC")
private List<DomainEntity> domains = new LinkedList<>();
@Column(columnDefinition = "TEXT")
private String description;
}

当尝试一遍又一遍地执行相同的操作时，这似乎与异步处理有关； hibernate会在我们的实体上跟踪更改，这称为脏检查，并减少了编译查询所需的时间，默认情况下，它包含更新查询中的所有字段，而不是仅包含已更改的字段。
尝试阅读有关@DynamicUpdate和@OptimisticLock注释的信息。
