有没有办法为嵌入式集合添加鉴别器？这是我所拥有的

  @MappedSuperclass
    @Inheritance(strategy = InheritanceType.SINGLE_TABLE)
    @DiscriminatorColumn(name = "type", discriminatorType = DiscriminatorType.STRING)
    public abstract class EncounterDataInfo implements Serializable {

        @Column(length = 50, nullable = false)
        private String name;

        @Column(length = 50, insertable = false, updatable = false)
        private String type;
}

@Embeddable
@DiscriminatorValue("DIAGNOSIS")
public class Diagnosis extends EncounterDataInfo {
}
@Embeddable
@DiscriminatorValue("MODIFIER")
public class Modifier extends EncounterDataInfo {
}
@Entity
@Table(name = "ENCOUNTER_DATA")
public class EncounterData extends AuditingEntity {
    @ElementCollection(targetClass = Diagnosis.class)
    @CollectionTable(name = "ENCOUNTER_DATA_INFO", joinColumns = @JoinColumn(name = "encounter_data_id"))
    private List<Diagnosis> diagnoses;

    @ElementCollection(targetClass = Modifier.class)
    @CollectionTable(name = "ENCOUNTER_DATA_INFO", joinColumns = @JoinColumn(name = "encounter_data_id"))
    private List<Modifier> modifiers;
}

目前，这两个字段的 EncounterData 实例都具有来自 meet_data_info 表的所有值，而不取决于类型。所以看起来鉴别器值不起作用？为什么以及如何使它工作？
