//注意在后面版本中(3.2 之后) annotationConfiguration 被去掉了//统一用Configuration config = new Configuration().configuration;//不分注解或xml配置方法Configuration config = new AnnotationConfiguration().configure();        Session session = config.buildSessionFactory().openSession();        Transaction tx = session.beginTransaction();
