春季数据-ManyToOne不持久

Question

在我的应用程序中，我有这三个类

@Entity
@Indexed
public class CpamEntity {

    @Id
    private String externalId;
    
    @Field
    private String cgr;
    
    @ElementCollection
    private Set<AttachmentEntity> attachments;
    
    @OneToMany(cascade = CascadeType.ALL)
    @JoinColumn(name = "externalId")
    private Set<DataEntity> data;

}

@Entity
@Indexed
public class DataEntity implements Serializable {

    private static final long serialVersionUID = 1L;

    @Id
    private String internalId;
    
    @Field
    private String number;

    @JsonIgnore
    @ManyToOne
    @JoinColumn(name = "externalId", updatable = false)
    private FrameworkEntity frameworkEntity;
    
}

下面的代码是将DataEntity（X）插入CpamEntity，然后通过IdChild获得所有附件CpamEntity并在其中插入相同的DataEntity（X）

问题是第一次插入没有发生，并且插入了附件CpamEntity

public void on(Event event) {
        CpamEntity cpamEntity = getCpamEntity(event.externalId);
        if (cpamEntity != null) {
            Set<DataEntity> datas = cpamEntity.getData();
            datas.add(new DataEntity(event.internalId, event.number));
            cpamEntity.setData(datas);
            repository.save(cpamEntity); // not saved
            if (CollectionUtils.isNotEmpty(cpamEntity.getAttachments())) {
                cpamEntity.getAttachments().forEach(attachment -> {
                    cpamRepositoryentity = repository.findByCgr(attachment.getIdChild());
                    if (entity != null) {
                        Set<Entity> dataEntities = entity.getData();
                        dataEntities.add(new DataEntity(event.internalId, event.number));
                        entity.setData(dataEntities);
                        cpamRepository.save(entity); // saved
                    }
                });
            }
        }
    }
