struts2.3.16+spring4.0.6+hibernate4.3.5整合出现的No Session found for current thread

在使用struts2+spring4+hibernate4出现了No Session found for current thread具体如下：

org.hibernate.HibernateException: No Session found for current thread

在网上查找有人说配上这个<propkey="hibernate.current_session_context_class">thread</prop>就可以解决，配上后再次测试出现org.hibernate.HibernateException:No
CurrentSessionContext configured!或save is not valid without active transacton异常

处理这个问题处理好久没解决，我原来的做法是service直接继承BaseDao和BaseDaoImpl，其中BaseDao和BaseDaoImpl在com.base包下，service在com.service包下

<!--
配置事务切面 -->

<aop:config>

<aop:pointcut id="serviceOperation"

expression="execution(* com.service..*.*(..))" />

<aop:advisor advice-ref="txAdvice" pointcut-ref="serviceOperation" />

</aop:config>

后来因为这个错误，尝试抽取BaseService和BaseServiceImpl并放在了com.base包下，结果同样报以上错误，后来突发奇想把BaseService和BaseServiceImpl移到了com.service，问题解决，测试通过
发现问题：配置的事务横切于在com.service包下所有类，而真正执行增删改查等数据库访问的方法是在com.Base包下。猜想：虽然service继承了BaseDao但是因为BaseDao不放在service包下，所以还是无法使用声明式事务管理...求高手帮验证...
