@Embeddable
public class AccountTransactionId implements Serializable {
    private String trxDate;
    private String acctNo;
    private int trxNo;
}

@Entity
public class Transaction {
    @EmbeddedId
    private AccountTransactionId accountTransactionId;

    private int amt;
    private int fee;
    private String cancelYn;
}

这是我的存储库。如何制作find方法？我对此一无所知

List<Map<String, Object>> findByAccountTransactionId_trxDate(String trxDate);

我尝试了“findByAccountTransactionId_trxDate”、“findByAccountTransactionIdTrxDate”、“findByIdTrxDate”...
