spring 注入问题？

Question

<!-- Dao是无状态的 是单例的 scope="singleton"
<bean id="userDao" class="com.test.dao.impl.UserDAOImpl"
scope="singleton">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean> <bean id="userService"
class="com.test.service.UserServiceImpl">
<property name="userDao" ref="userDao"></property>
</bean>
 -->
 
 
<!--控制层-->
<!--id="saveUserAction" 别名--><!-- scope:prototype 生产新的action-->

<bean id="listUserAction"
class="com.test.action.user.ListUserAction" scope="prototype">
<property name="service" ref="userService"></property>
</bean>现在不定义接口了，就是那个 userDao和userService 没了，注释部分怎么改写啊？？
