service 服务居必须使用面向接口的方式编程

如果采用spring声明式管理后,直接调用DAO的方式并能不保存数据
DemoDAO demoDAO=(DemoDAO)cpac.getBean("demoDAO");
Demo d=new Demo();
d.setName("小pei");
d.setAge(558);
demoDAO.save(d);
这是为什么??同事说加上
<bean id="userInfoDAOProxy" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
<property name="transactionManager">
<ref bean="transactionManager" />
</property>
<property name="target">
<ref local="userInfoDAOImpl" />
</property>
<property name="transactionAttributes">
<props>
<prop key="insert*">PROPAGATION_REQUIRED</prop>
<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
</props>
</property>
</bean>
DAO也采用代理的方式就可以不跟过Service层直接能操作DB,我想应该是这样,但没试用
通过spring 的ApplicationContext获取服务实例时只能使用接口如
IService ds =(IService)cpac.getBean("demoService");
而不是能是对象!!!
乱,仅做个人笔记
