    public interface VillageRepository extends JpaRepository<Village, Long> {
    }

我的問題是 parseLink 方法中的 object 村沒有保存到數據庫中......沒有任何反應，甚至沒有出現錯誤......當我嘗試使用測試參數在主要方法中保存 object 時，它可以工作，但是不是我需要的地方...當我嘗試在該方法中保存不同的東西時，什么也沒有發生，所以問題一定出在方法 parseHTML 我猜謝謝您的幫助

PS：在 intelij 中，我可以看到創建的插入命令似乎沒問題，但數據庫中沒有任何內容......

Answer 1

嘗試將@Transactional注釋放在公共函數上，而不是 class。

Answer 2

我不知道你是如何真正分配到類中的，但是你的 JpaRepository 是用注釋 @Repository 裝飾的嗎？
