我遇到問題，Hibernate正在查詢懶惰onetoone關係的另一端的類。休眠JPA OneToOne查詢儘管懶惰取指
對top_players的查詢取決於緩存設置，通過映射表執行查詢以獲取QHPlayer表的ID。
完成主查詢後，它將查詢QHPlayer表的每個實例。
但是，它在兩種不同的情況下做錯了事。
如果我打開了緩存，它將查詢QHPlayer的實例，然後它將查詢到inventory_item表。 如果我關閉了緩存，它將通過與inventory_item的連接向QHPlayer進行查詢。
問題是，無論我怎麼做，它都堅持查詢inventory_item表。這是我不想要的。目前我不需要inventory_item中的數據 。
我假設QHPlayer和PlayerInventoryItem之間的onetoone聲明有問題。
有什麼想法嗎？
相關的代碼如下：
Query query = entityManager.createQuery("SELECT c FROM top_players c WHERE c.teamId=:teamId ORDER BY c.level DESC, c.adjustedFantasyPointsTotal DESC, c.id ASC");
query.setParameter("teamId", teamId);
List<TopPlayers> results = query.getResultList();
