Question

当我使用此查询时，总是显示错误为什么？在审计类中使用MappedSuperclass。

@Query("select new  com.brite.domain.CurrencyConversion(ins.id,ins.contractType,ins.symbol,ins.exchange,ins.currency,ap.allocationQty,ap.createdDate,ca.baseCurrency,hd.close) from ActualPortfolio as ap JOIN  Instrument as ins on ins.id=ap.instrument.id JOIN  HistoricalData as hd on hd.instrumentId = ins.id   Join ClientAccount as ca on ca.accountId = ap.clientAccount.accountId  where ap.clientAccount.accountId =:accountId and ap.createdDate = (select MAX(pf.createdDate) as date from ActualPortfolio pf where  ap.clientAccount.accountId =:accountId and pf.createdDate =: createdDate) and hd.dateTime = (select to_char(MAX(pf.createdDate), 'YYYY-MM-DD 00:00:00') as date from ActualPortfolio pf where  ap.clientAccount.accountId =:accountId and pf.createdDate =: createdDate)")

Pojo类的外观

        @Entity
        @EntityListeners(AuditingEntityListener.class)
        public class Transaction extends Audit {    
            private Long Id;     

        }

，审核类别为

        @MappedSuperclass
        public class Audit {

            @Column(name = "createdDate", columnDefinition = "TIMESTAMP WITH TIME ZONE")
            @CreatedDate
            @JsonSerialize(using = CustomDateSerializer.class)
            private LocalDateTime createdDate;

        }

由以下原因引起：java.lang.IllegalStateException：将命名参数用于方法公共抽象java.util.List com.brite.repository.InstrumentRepository.getInstrumentForCurrencyConverstion（java.lang.String，java.time.LocalDateTime）但是在带注释的查询中找不到参数“ Optional [createdDate]” '选择新 com.brite.domain.CurrencyConversion（ins.id，ins.contractType，ins.symbol，ins.exchange，inscurrency，ap.allocationQty，ap.createdDate，ca.baseCurrency，hd.close）从ActualPortfolio那里作为ap JOIN Instrument从ins开始 ins.id = ap.instrument.id在hd.instrumentId上将HistoricalData作为hd加入 = ins.id以ca.accountId上的ca身份加入ClientAccount = ap.clientAccount.accountId，其中ap.clientAccount.accountId =：accountId和ap.createdDate =（选择MAX（pf.createdDate）作为ActualPortfolio pf中的日期，其中ap.clientAccount.accountId =：accountId 和enter code here pf.createdDate =：createdD enter code here 和hd.dateTime = enter code here（选择 to_char（MAX（pf.createdDate），'YYYY-MM-DD 00:00:00'）作为起始日期 ActualPortfolio pf，其中ap.clientAccount.accountId =：accountId和 pf.createdDate =：createdDate）'！

Answer 1

在我看来，您正在将Optional Argument传递给方法。那可能会引起问题。

Answer 2

谢谢，我的查询出了点问题。我们不需要在查询中的冒号'：'后面放置空格
