这是我的实体类

@Entity
@Table(name = "sofort_payment")
@Data
@EqualsAndHashCode(callSuper = true)
@Accessors(chain = true)
@AllArgsConstructor
@NoArgsConstructor
@Builder
@ToString
public class SofortPaymentEntity extends BasicEntity {

    @Id
    @GeneratedValue(generator = "UUID")
    @GenericGenerator(name = "UUID", strategy = "org.hibernate.id.UUIDGenerator")
    @Column(name = "id", updatable = false, nullable = false)
    private UUID id;
    @Column(name = "referenced_transaction")
    private UUID referencedTransaction;
    @Column(name = "status")
    private String status;
    @Column(name = "reason")
    private String reason;
    @Column(name = "external_payment_id")
    private String externalPaymentId;
    @Column(name = "currency")
    private String currency;
    @Column(name = "amount")
    private BigDecimal amount;
    @Column(name = "iban")
    private String iban;
    @Column(name = "back_name")
    private String bankName;
    @Column(name = "sender_holder")
    private String senderHolder;
    @Column(name = "bic")
    private String bic;
    @Column(name = "bank_code")
    private String bankCode;
    @Column(name = "country_code")
    private String countryCode;

}

我的基本实体类

@MappedSuperclass
@Data
@Accessors(chain = true)
public abstract class BasicEntity {
  @Column(name = "created_at")
  @CreationTimestamp
  private LocalDateTime createdAt;
  @Column(name = "updated_at")
  @UpdateTimestamp
  private LocalDateTime updatedAt;
}

我的表结构：

create table sofort_payment
(
    id                          UUID         NOT NULL
        constraint sofort_payment_pkey primary key,
    referenced_transaction      UUID references transaction(id) NOT NULL,
    status                      varchar(255) NOT NULL,
      reason                      text,
    external_payment_id         varchar(255) NOT NULL,
    currency                    varchar(255) NOT NULL,
    amount                      numeric(19, 2) NOT NULL,
      iban                        varchar(255) NOT NULL,
      back_name                   varchar(255) NOT NULL,
    sender_holder               varchar(255) NOT NULL,
    bic                         varchar(255) NOT NULL,
    bank_code                   varchar(255) NOT NULL,
    country_code                varchar(255) NOT NULL,
    created_at                  timestamp without time zone NOT NULL,
    updated_at                  timestamp without time zone NOT NULL
);

但是，当我尝试打印SofortPaymentEntity时，它没有打印crated_dt和UPDATE_dt，并且当我尝试更新它时，抛出以下异常。该表已经具有条目，这意味着它是首先创建的，现在我正在尝试更新它

sofortPaymentRepository.save(sofortPaymentEntity.builder()
                                                 .id(sofortPaymentEntity.getId())
                                                 .referencedTransaction(sofortPaymentEntity.getReferencedTransaction())
                                                 .externalPaymentId(statusNotification.getTransId())
                                                 .amount(BigDecimal.valueOf(paymentTransactionDetails.getAmount()))
                                                 .currency(paymentTransactionDetails.getCurrencyCode())
                                                 .reason(paymentTransactionDetails.getStatusReason().toString())
                                                 .bankCode(paymentTransactionDetails.getSender().getBankCode())
                                                 .bankName(paymentTransactionDetails.getSender().getBankName())
                                                 .bic(paymentTransactionDetails.getSender().getBic())
                                                 .iban(paymentTransactionDetails.getSender().getIban())
                                                 .countryCode(paymentTransactionDetails.getSender().getCountryCode())
                                                 .senderHolder(paymentTransactionDetails.getSender().getHolder())
                                                 .status(paymentTransactionDetails.getStatus().toString()).build());

错误：

null value in column "created_at" violates not-null constraint

捕获到通用异常：
