Question

I have a table structure like that :- 

    @Entity
@Table(name = "Load_Container_Tray")
public class LoadContainerTray {

    @EmbeddedId
    private LoadContainerTrayPK loadContainerTrayPK;

    @MapsId("loadContainerPK")
    @JoinColumns({
        @JoinColumn(name = "dest_ebu_nbr", referencedColumnName = "dest_ebu_nbr"),
        @JoinColumn(name = "outbound_load_id", referencedColumnName = "outbound_load_id"),
        @JoinColumn(name = "dest_ebu_cntry_code", referencedColumnName = "dest_ebu_cntry_code"),
        @JoinColumn(name = "ctnr_trackg_id", referencedColumnName = "ctnr_trackg_id") })
    @ManyToOne
    private LoadContainer loadcontainer;
}

@Embeddable 公共类LoadContainerTrayPK实现Serializable {

private static final long serialVersionUID = 3392075534159950245L;

@Basic
private LoadContainerPK loadContainerPK;

@Column(name = "load_unit_id", columnDefinition = "char(32)")
private String loadUnitId;

}

@Entity
@Table(name = "load_container")
public class LoadContainer {

    @EmbeddedId
    private LoadContainerPK loadContainerPK;

    @MapsId("loadDestinationPK")
    @JoinColumns({
        @JoinColumn(name = "dest_ebu_nbr", referencedColumnName = "dest_ebu_nbr"),
        @JoinColumn(name = "outbound_load_id", referencedColumnName = "outbound_load_id"),
        @JoinColumn(name = "dest_ebu_cntry_code", referencedColumnName = "dest_ebu_cntry_code") })
    @ManyToOne
    private LoadDestination loadDestination;

    @Column(name = "row_nbr")
    private short rowNumber;
}

@Embeddable
public class LoadContainerPK implements Serializable {

    private static final long serialVersionUID = 3392075534159950245L;

    @Basic
    private LoadDestinationPK loadDestinationPK;

    @Column(name = "ctnr_trackg_id")
    private String containerTrackingId;
}

public class LoadDestination {

@EmbeddedId
    private LoadDestinationPK loadDestinationPK;

    @MapsId("outboundLoadId")
    @JoinColumn(name = "outbound_load_id", referencedColumnName = "outbound_load_id")
    @ManyToOne
    private OutboundLoad outboundLoad;

}

@Embeddable
public class LoadDestinationPK implements Serializable {

    private static final long serialVersionUID = -3548089581858405303L;

    @Column(name = "outbound_load_id")
    private String outboundLoadId;

    @Column(name = "dest_ebu_nbr")
    private Integer destinationId;

    @Column(name = "dest_ebu_cntry_code")
    private String destEbuCntryCode;

}
@Entity
@Table(name = "outbound_load")
public class OutboundLoad {

    @Id
    @Column(name = "outbound_load_id", columnDefinition = "char(30)")
    private String outboundLoadId;

    @Column(name = "load_id")
    private int loadId;
}

当我尝试在TOMEE服务器上部署应用程序时，我收到此错误： -

＆＃34; org.apache.openejb.OpenEJBException：org.apache.openejb.OpenEJBRuntimeException：org.hibernate.AssertionFailure：映射@MapsId时引用实体上的意外嵌套组件：com.walmart.move.nim.outdoc.entity.LoadContainer：org .hibernate.AssertionFailure：映射@MapsId时引用实体上的意外嵌套组件：com.walmart.move.nim.outdoc.entity.LoadContainer。

有人可以帮我解决问题。

Answer 1

我认为你应该注释 private LoadDestinationPK loadDestinationPK;中的LoadContainerPK @Embedded代替@Basic，为什么要使用@Basic对其进行注释？如何将此类映射为基本类型？
