我有一个springboot应用程序，并有一个自定义实现来记录JPA实体的更改历史记录。
我的主要实体是Test，它从Base类扩展而来。基类具有以下注释
@EntityListeners(HistoryEntityUpdater.class)
@Inheritance(strategy = InheritanceType.JOINED)
@DiscriminatorColumn(name = "object_type")
我有一个自定义实体监听器，其方法使用@PostPersist和@PostUpdate进行批注。在这些方法中，我创建了TestHistory的实例并调用entityManager.persist。虽然这样可行，但有些历史记录没有插入。这是调用保存时的日志，但数据库未更新。

postUpdate上的postPersist和HistoryEntityUpdater方法注释为@Transactional
答案 0 :(得分：2)
JPA规范规定EntityListeners不应使用EntityManager。 这使得它们对大多数用例都没用，包括你的用例。
我也不知道。
从您的堆栈跟踪看起来，JDBC事务已经提交，并且实体管理器已刷新。 所以至少你的听众运行时没有任何交易。这可能会导致写入的历史实体未写入数据库。 EntityListener由hibernate调用，而不是由spring调用，因此侦听器上的任何@Transactional注释都不起作用。
最后有一个解决方案，使用＆＃39; Envers＆＃39;实施实体审计：
