通用dao

List list = getHibernateTemplate().find(hql,values);

return list.get(0);

}
}
spring配置
<bean id="baseDao" class="com.test">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>
其他dao继承上面通用dao,启动服务还是报那个子类不能建立,sessionFactory or HibernateTemplate is required
Basedao明明就对sessionFactory进行注入了啊.
spring的配置给全呀
