hibernate.ejb.interceptor 不“拦截”，Spring+JPA

Question

各位 - 我正在尝试设置 hibernate.ejb.interceptor 但由于某种原因它永远无法“拦截”任何更新或插入事件。该应用程序似乎工作正常，更新和插入实体但没有拦截。

我找不到我的设置有什么问题，请帮助：

persistence.xml：

拦截器（来自曼宁书）：

public class AuditLogInterceptor extends EmptyInterceptor {
    /**
     * 
     */
    private static final long serialVersionUID = -634733855120326803L;

    /**
     * 
     */
    private XLogger logger = XLoggerFactory
            .getXLogger(AuditLogInterceptor.class.getName());

    private Session session;
    private Long userId;
    private Set<Auditable> inserts = new HashSet<Auditable>();
    private Set<Auditable> updates = new HashSet<Auditable>();

    public AuditLogInterceptor() {}

    public void setSession(Session session) {
        this.session = session;
    }

    public void setUserId(Long userId) {
        this.userId = userId;
    }

    @Override
    public boolean onSave(Object entity, Serializable id, Object[] state,
            String[] propertyNames, Type[] types) throws CallbackException {
        logger.entry(entity, id, state, propertyNames);

        if (entity instanceof Auditable)
            inserts.add((Auditable) entity);

        logger.exit();

        return false;
    }

    @Override
    public boolean onFlushDirty(Object entity, Serializable id,
            Object[] currentState, Object[] previousState,
            String[] propertyNames, Type[] types) throws CallbackException {
        logger.entry(entity, id, currentState, previousState);

        if (entity instanceof Auditable)
            updates.add((Auditable) entity);

        logger.exit();

        return false;
    }

    @Override
    public void postFlush(Iterator iterator) throws CallbackException {
        logger.entry(iterator);

        try {
            for (Auditable entity : inserts) {
                AuditLog.logEvent("create", entity, "userId");
            }           

            for (Auditable entity : inserts) {
                new AuditLog().logEvent("update", entity, "userId");
            }

        } finally {
            inserts.clear();
            updates.clear();
        }

        logger.exit();
    }
}

Spring bean（在网上找到的）：

public class AuditLog {

    static protected AuditLog theAuditLog = null;

    @PersistenceContext(unitName = "myPU")
    protected EntityManager itsEntityManager;

    public AuditLog() {
        theAuditLog = this;
    }

    /**
     * 
     * @return the entity manager
     */
    protected EntityManager getEntityManager() {
        return this.itsEntityManager;
    }

    /**
     * 
     * @return Hibernate Session
     */
    protected Session getHibernateSession() {
        return (Session) getEntityManager().getDelegate();
    }

    public static void logEvent(String action, Auditable entity, String userId) {
        /*
         * TODO get rid of this .connection() - deprecated - call !
         */
        Session tempSession = theAuditLog.getHibernateSession()
                .getSessionFactory()
                .openSession(theAuditLog.getHibernateSession().connection());

        try {
            AuditLogRecord alr = new AuditLogRecord();
            alr.entityId = entity.getId();
            alr.entityClass = entity.getClass();
            alr.message = "Something changed";
            alr.created = new Date();

            tempSession.save(alr);
            tempSession.flush();
        } catch (Exception ex) {
            throw new CallbackException(ex);
        } finally {
            try {
                tempSession.close();
            } catch (HibernateException ex) {
                throw new CallbackException(ex);
            }
        }
    }
}
