Question

我需要将JpaRepository与一个内部具有union语句的查询一起使用。可能吗？这是我目前的实现和我到目前为止的错误：

实体：

@Entity
public class PaymentDetails {
  @Id
  @Column
  private String id;
  @Enumerated(EnumType.STRING)
  @Column(name = "rowtype")
  private PaymentType paymentType;
  @Embedded
  private CardDetails cardDetails;
  @Embedded
  private BankAccountDetails bankAccountDetails;

界面和查询：

public interface PaymentsRepositoryManagerPayment1 extends JpaRepository<PaymentDetails,String> {
  @Query(value = "select id,'CARD' as rowtype, cardnumber, cardtype, nameoncard, expirydate, startdate, securitycode, semafonecr, issuenumber, "
        + "null accountnumber, null accountholdername, null sortcode, null bic, null iban, null currency from pcs.BsbTempCardDetails "
        + "where id = :id union all select id, 'BANK' as rowtype, null cardnumber, null cardtype, null nameoncard, null expirydate, null startdate, "
        + "null securitycode, null semafonecr, null issuenumber, accountnumber, accountholdername, sortcode, bic, iban, currency "
        + "from pcs.BsbTempBankAccountDetails where id = :id", nativeQuery = true) <br>
List< PaymentDetails > findPaymentDetails(@Param("id") String id);

呼叫：

@Autowired private PaymentsRepositoryManagerPayment1 paymentsRepositoryManagerPayment1;
@Transactional(value = "paymentsRepositoryTransactionManager")
public PaymentDetails retrievePaymentDetailsById1(String id) {
  return paymentsRepositoryManagerPayment1.findOne(id);
}

ERROR：

您展示的所有内容似乎与您看到的例外情况无关：

关于桌子不可用的例外投诉。发出查询时确保PaymentDetails存在（这可能是的原因，您看到异常）。
您致电findOne(…)。因此，findPaymentDetails(…)上的查询声明根本不会影响用例。

如何使用union all statment进行本机查询时如何使用JpaRepository操作（findOne）
