jpa - 列出 OneToMany 未保存

问题描述

我有下面的房间实体，它有很多disponibilities，当我添加一个带有disponibilities 列表的房间时，房间被保存，但列表没有。我在这段关系中缺少什么？

@Entity
public class RoomEntity {

    @Id
    private String classRoomId;

    private String label;

    @OnetoMany(mappedBy = "room",fetch = FetchType.LAZY,cascade = CascadeType.ALL)
    private List<disponibilityEntity> disponibilities;

    public void adddisponibilities(List<disponibilityEntity> disponibilityEntities) {
        if (CollectionUtils.isEmpty(disponibilities)) {
            disponibilities = new ArrayList<>();
        }
        disponibilities.addAll(disponibilityEntities);
        disponibilityEntities.forEach(item -> item.setRoom(this));
    }

}


@Entity
public class disponibilityEntity {

    @Id
    private String disponibilityId;

    @JsonIgnore
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumn(name = "fk_room")
    private RoomEntity room;
}

roomEntity.adddisponibilities(classRoomEntity.getdisponibilities());
roomrepository.save(roomEntity);
