Spring JavaFX@Transactional entitymanager已关闭

我在JavaFX应用程序中使用Spring@Transactional时遇到了事务性问题，我所有的bean和图形组件都由Spring管理

我在控制器上使用@PostConstruct初始化应用程序。 在PostConstruct中，我所有的DAO都工作得很好，但是当我通过按下JavaFX按钮调用服务来保存某些内容时，我遇到了这个异常

有人知道为什么entityManager不能在方法上使用@Transactional打开事务吗

我的hibernate bean配置：

http://www.springframework.org/schema/beans/spring-beans.xsd “>

我的Dao方法：

    /** {@inheritDoc}*/
@SuppressWarnings("unchecked")
@Override
public final P saveOrUpdate(final T o) {
    if (entityManager.getEntityManagerFactory().getPersistenceUnitUtil().getIdentifier(o) == null) {
        entityManager.persist(o);
    } else {
        entityManager.merge(o);
    }
    return (P) entityManager.getEntityManagerFactory().getPersistenceUnitUtil().getIdentifier(o);
}

提前谢谢。

通过阅读日志，我了解了发生了什么

一个线程正在关闭applicationContext，并隐式关闭包括entityManagerFactory在内的所有单例bean

entityManagerFactory在每个PersistenceUnit生命周期中只能打开一次

---

当事务试图打开一个工厂已关闭的entityManager时，它会抛出一个异常。

没有配置扫描@Transactional。对不起，我忘记了我的服务上下文，我编辑了我的问题。因此，TemplateEditorController.handleSaveGameAction方法正在调用saveGame方法？什么类/pa是否在中保存游戏？是的，控制器正在类com.cardassiel.core.service.SimpleGameService中调用服务方法实现com.cardassiel.core.service.GameService
