spring使用注解方式实例化类之后 事务就失去了效果。

spring使用注解方式实例化类之后 事务就失去了效果。。求助！！！！！！
没用 注解之前 用的是声明式 事务  用了后  会出现 no session  某些页面 标签拿不到值  提示  session  已关闭。。 
下面上 配置文件  

	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="configLocation" value="classpath:hibernate.cfg.xml">
		</property>
	</bean>
	
	<!-- *******************************动态代理事务*********************************** -->
	<!-- 配置事务 -->
	<bean id="transactionManager"
		class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>
	
	<!--  <tx:annotation-driven transaction-manager="transactionManager" /> -->
	
	
 	<bean id="transactionInterceptor"
		class="org.springframework.transaction.interceptor.TransactionInterceptor">
		<property name="transactionManager" ref="transactionManager" />
		<!-- 配置事务属性 -->
		<property name="transactionAttributes">
			<props>
				<prop key="*">PROPAGATION_REQUIRED</prop>
			</props>
		</property>
	</bean>
	

	<bean
		class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
		<property name="beanNames">
			<list>
				<value>*Dao</value>
			</list>
		</property>
		<property name="interceptorNames">
			<list>
				<value>transactionInterceptor</value>
			</list>
		</property>
	</bean>

	
	<!-- 自动扫描dao和service包(自动注入) -->
	<context:component-scan base-package="com.syyx.officemanage" />

上面是 spring 配置文件


然后访问 需要操作数据库的标签页后 就出现 2013-12-26 17:20:49,655 ERROR [org.hibernate.LazyInitializationException] - could not initialize proxy - no Session

没用注解之前没问题  都是在jsp加载完毕后才关闭 session  现在 没加载完就关闭了。
