@ManyToOne 带有计数和带有条件构建器的子查询

如何解决@ManyToOne 带有计数和带有条件构建器的子查询

我需要使用标准构建器执行以下查询（获取公告列表以及用户是否将此公告添加到收藏夹）。

@Entity
class FavouriteAnnouncement(
    @ManyToOne(fetch = FetchType.LAZY) var announcement: Announcement? = null,var userId: Long? = null
) : BaseEntity()

@Entity
class Announcement(
    var title: LocalizedString? = null,var categoryId: Long? = null,var location: Location? = null,var sum: String? = null,var primaryPhotoHashId: String? = null,var promotionorder: Int = 0
) : BaseEntity()

我需要的自定义查询如下：

select id,created_date,latitude,longitude,primary_photo_hash_id,promotion_order,sum,en,ru,uz_cyr,uz_lat,(select count(fa.announcement_id) as favourite_count
        from favourite_announcement fa
        where a.id = fa.announcement_id
          and a.deleted = false
          and user_id = 6)
from announcement a
where deleted = false
  and category_id = 1
  and promotion_order in (0,1,-1)
order by created_date desc,promotion_order desc;
