Java 如何在spring配置中手动连接hibernate会话工厂

我有hibernate上下文

<context:property-placeholder location="/WEB-INF/spring.properties" />

    <!-- Enable annotation style of managing transactions -->
    <tx:annotation-driven transaction-manager="transactionManager" />   

    <!-- Declare the Hibernate SessionFactory for retrieving Hibernate sessions -->
    <!-- See http://static.springsource.org/spring/docs/3.0.x/javadoc-api/org/springframework/orm/hibernate3/annotation/AnnotationSessionFactoryBean.html -->                           
    <!-- See http://docs.jboss.org/hibernate/stable/core/api/index.html?org/hibernate/SessionFactory.html -->
    <!-- See http://docs.jboss.org/hibernate/stable/core/api/index.html?org/hibernate/Session.html -->
    <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
                 p:dataSource-ref="dataSource"
                 p:configLocation="${hibernate.config}"
                 p:packagesToScan="com.vaannila"/>

    <!-- Declare a datasource that has pooling capabilities-->   
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"
                destroy-method="close"
                p:driverClass="${app.jdbc.driverClassName}"
                p:jdbcUrl="${app.jdbc.url}"
                p:user="${app.jdbc.username}"
                p:password="${app.jdbc.password}"
                p:acquireIncrement="5"
                p:idleConnectionTestPeriod="60"
                p:maxPoolSize="100"
                p:maxStatements="50"
                p:minPoolSize="10" />

    <!-- Declare a transaction manager-->
    <bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager" 
                p:sessionFactory-ref="sessionFactory" />

</beans>

现在我想在我的DAO构造函数中传递sessionFactory，如下所示

<bean id="registrationDAO" class="com.vaannila.dao.RegistrationDAOimpl" >
     <constructor-arg ref="sessionFactory"/>
     </bean>

但错误表明找不到bean sessionfactory

原因：org.springframework.beans.factory.BeanCreationException:创建名为“registrationDAO”的bean时出错，该名称在ServletContext资源[/WEB-INF/applicationContext.xml]中定义：设置构造函数参数时无法解析对bean“sessionFactory”的引用；嵌套异常为org.springframework.beans.factory.NoSuchBeanDefinitionException:未定义名为“sessionFactory”的bean 位于org.springframework.beans.factory.support.BeanDefinitionValueResolver.resolveReference（BeanDefinitionValueResolver.java:328）

这是我的工作

<bean id="hibernateSessionFactory"
                class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="configLocation">
            <value>classpath:/hibernate.cfg.xml</value>
        </property>
        <property name="dataSource" ref="dataSource">
        </property>
</bean>


<bean id="hibernateTransactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="hibernateSessionFactory" />
</bean>


<bean class="com.vaannila.dao.RegistrationDAOimpl"
        id="registrationDAO">
        <property name="sessionFactory">
            <ref bean="hibernateSessionFactory" />
        </property>
</bean>

类路径：/hibernate.cfg.xml

我确信错误说明的不止这些。它还说了什么？我认为这很明显，因为sessionfactory是在不同的xml文件中定义的，而DAO是在applicationContext中定义的，但我添加了tat错误
