自从上周五以来，我一直在处理一个hibernate问题，非常感谢大家对我的帮助

在执行简单的获取查询时，我遇到了hibernate的问题。我有两个表：

Trade

和

TradeDetails

。交易与交易详情之间存在一对一的单向关系

表结构：

实体定义：

@Entity(name = "Trade")
@Table(name = "trade", uniqueConstraints = @UniqueConstraint(columnNames = {"trade_num", "fund", "stop_date"}))
public class Trade {
    @EmbeddedId
    private TradePK tradePK;

    @OneToOne(cascade = CascadeType.ALL, fetch = FetchType.EAGER)
    @JoinColumns({
            @JoinColumn(name = "fund", referencedColumnName = "fund"),
            @JoinColumn(name = "cusip", referencedColumnName = "cusip"),
            @JoinColumn(name = "trade_num", referencedColumnName = "trade_num"),
            @JoinColumn(name = "start_date", referencedColumnName = "pos_date"),
//            @JoinColumn(name = "pos_date", referencedColumnName = "start_date"),
            @JoinColumn(name = "stop_date", referencedColumnName = "stop_date")
    })
    private TradeDetails tradeDetails;

    @Column(name = "description")
    private String description;
}

@Embeddable
public class TradePK  implements Serializable {
    @Column(name = "start_date", nullable = false)
    private Date startDate;

    @Column(name = "stop_date", nullable = false)
    private Date stopDate;

    @Column(name = "fund")
    private int fund;

    @Column(name = "cusip", nullable = false)
    private String cusip;

    @Column(name = "trade_num")
    private int tradeNum;
}

@Entity(name = "TradeDetails")
@Table(name = "trade_details")
public class TradeDetails {
    @EmbeddedId
    private TradeDetailsPK tradeDetailsPK;

    @Column(name = "amount")
    private float amount;

    @Column(name = "broker_name")
    private String brokerName;
}

@Embeddable
public class TradeDetailsPK implements Serializable {
    @Column(name = "fund")
    private int fund;

    @Column(name = "pos_date", nullable = false)
    private Date posDate;

    @Column(name = "cusip", nullable = false)
    private String cusip;

    @Column(name = "trade_num")
    private int tradeNum;

    @Column(name = "stop_date", nullable = false)
    private Date stopDate;
}

这是我的存储库类：

@Repository
public interface TradeRepository extends JpaRepository<Trade, TradePK> {
    String QUERY = "select T.* " +
            "from trade T, trade_details TD " +
            "where T.fund = :fund " +
            "and T.cusip = :cusip " +
            "and TD.fund = T.fund " +
            "and TD.cusip = T.cusip " +
            "and TD.trade_num = T.trade_num";

    @Query(value = QUERY, nativeQuery = true)
    List<Trade> findTradeByFundAndCusip(@Param("fund") int fund, @Param("cusip") String cusip);
}

我认为问题在于

@OneToOne

。我之所以这样说，是因为当我将关系更改为

@OneToMany

时，我能够获取数据。但是我不明白，

@OneToOne

有什么问题。如果类的id类型错误，我甚至无法理解id不匹配是怎么可能的


注:
无法更改表结构、数据库的状态
无法更改
此外，我正在使用lombok库-在模型类中使用@Data
、@allargsconstuctor
和noargsconstuctor
将我的示例代码添加到github：

由于方法FindTradeByFund和CUSIP
返回一个列表
，因此查询应以从交易T中选择T开始，交易详细信息TD
而不是从…中选择*；另外，使用本机查询是否有充分的理由？抱歉，复制和粘贴时的疏忽。它是T.*
，但不知何故它被修改为*
。在这里和我的示例代码中将其更改为*
。我也看到了同样的问题anyways@Jesper-不，我不熟悉hibernate，从hibernate文档中学习。所以我从原生SQL开始，但我的计划是利用SpringDataJPA的方法，比如publicList findTradeByFundAndCusip（int-fund，String-cusip）
