我試圖實作一個具有多對多關系的資料庫。資料庫已經建立，現在我們需要對其進行查詢。我以這篇文章為例：https ://www.bezkoder.com/jpa-many-to-many/ 。當我在存盤庫中創建自定義查找器時 - 服務器在運行時崩潰。
我有兩個物體：MassageEntity 和 RstringsEntity。我正在嘗試創建一個方法List<MasageEntity> findMasageEntitiesByRstringsEntitiesId(Long string_id);。如果沒有該方法，服務器將啟動。
這就是錯誤的樣子。

我看不出顯示控制器的意義，因為錯誤發生在其他地方。
我做錯了什么？也許我需要一些設定或依賴項？或者我可以用不同的方式解決問題？
uj5u.com熱心網友回復：
您的問題是查詢方法的名稱：findMasageEntitiesByRstringsEntitiesId(Long. 您需要使用物體類中的欄位名稱，而不是類名稱。
我會嘗試findMasageEntitiesByStringsId(Long...。（您給變數一個名稱而給 getter 方法另一個名稱，這也有點令人困惑，不確定 JPA 是否會喜歡這樣。）
回傳串列的其他方法也遇到同樣的問題。
