我有一個springboot應用程序，並有一個自定義實現來記錄JPA實體上的更改歷史記錄。Spring JPA有時跳過插入實體
我的主要實體是測試，它從基類擴展。基類具有以下注釋
@EntityListeners(HistoryEntityUpdater.class)
@Inheritance(strategy = InheritanceType.JOINED)
@DiscriminatorColumn(name = "object_type")
我與@PostPersist和@PostUpdate註解的方法自定義實體監聽器。在這些方法中，我創建了一個TestHistory的實例並調用entityManager.persist。雖然這可行，但一些歷史記錄沒有被插入。以下是調用保存時的日誌，但數據庫未更新。
