我有类Money是@Embeddable

@Embeddable
public class Money implements Serializable, Comparable<Money> {
    @Column(name = "amount", precision = 15, scale = 2)
    private BigDecimal amount;
}

当我在实体内部使用多次时,一切正常.例如

@Entity
public class SomeEntity implements Serializable {

    @Embedded
    @AttributeOverride(name = "amount", column = @Column(name = "entry"))
    private Money entryValue;

    @Embedded
    @AttributeOverride(name = "amount", column = @Column(name = "leave"))
    private Money leaveValue;
}

上面的代码完美无缺.

现在问题出现了,当我有另一个@Embeddable,我希望在其中有Money实例,并且实体多次使用@Embeddable.例:

1. 嵌入式

   @Embeddable
   public class ReportCostValues implements Serializable {
   
       @Embedded
       @AttributeOverride(name = "amount", column = @Column(name = "covered_by_grant"))
       private Money coveredByGrant;
   
       @Embedded
       @AttributeOverride(name = …
