我正在使用弹簧和休眠。Hibernate 4.2Ejb3Configuration将类声明为已弃用，并且它没有允许设置侦听器的方法getEventListeners 。这个类用来搞定EntityManagerFactory。

我用它来进行数据库试听（更新、插入、删除事件的记录）。我应该如何获得带有试听配置的 EntityManagerFactory？

public class HibernateExtendedPersistenceProvider extends HibernatePersistence {

    private PostInsertEventListener[] postInsertEventListeners;
    private PostUpdateEventListener[] postUpdateEventListeners;
    private PostDeleteEventListener[] postDeleteEventListeners;

    @SuppressWarnings("rawtypes")
    @Override
    public EntityManagerFactory createEntityManagerFactory(String persistenceUnitName, Map properties) {
        Ejb3Configuration cfg = new Ejb3Configuration();
        setupConfiguration(cfg);
        Ejb3Configuration configured = cfg.configure( persistenceUnitName, properties );
        return configured != null ? configured.buildEntityManagerFactory() : null;
    }

    @SuppressWarnings("rawtypes")
    @Override
    public EntityManagerFactory createContainerEntityManagerFactory(PersistenceUnitInfo info, Map properties) {
        Ejb3Configuration cfg = new Ejb3Configuration();
        setupConfiguration(cfg);
        Ejb3Configuration configured = cfg.configure( info, properties );
        return configured != null ? configured.buildEntityManagerFactory() : null;
    }

    private void setupConfiguration(Ejb3Configuration cfg) {
        // 4.2: Ejb3Configuration deprecated and has no method getEventListeners
        cfg.getEventListeners().setPostInsertEventListeners(postInsertEventListeners); 
        cfg.getEventListeners().setPostDeleteEventListeners(postDeleteEventListeners);
        cfg.getEventListeners().setPostUpdateEventListeners(postUpdateEventListeners);
    }

    public void setPostInsertEventListeners(PostInsertEventListener[] postInsertEventListeners) {
        this.postInsertEventListeners = postInsertEventListeners;
    }

    public void setPostUpdateEventListeners(PostUpdateEventListener[] postUpdateEventListeners) {
        this.postUpdateEventListeners = postUpdateEventListeners;
    }

    public void setPostDeleteEventListeners(PostDeleteEventListener[] postDeleteEventListeners) {
        this.postDeleteEventListeners = postDeleteEventListeners;
    }
}

如果您可以控制源代码，我会看看 hibernate envers。它在版本控制方面做得很好。它不仅像更新的审计跟踪，而且跟踪旧的实体版本。

JPA 实体侦听器 api 的缺点是您无法轻松访问更改之前的原始值。您必须从某个地方获取这些值才能创建增量。

您仍然可以注册您的休眠事件侦听器，但现在推荐的方法是使用 SPI。查看 Hibernate Integrator 以了解它是如何完成的。
