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。

[解决办法]

是不是有其他操作，把当前连接关掉了

很有可能
[解决办法]
打开注解之后，事务也是注解的，在需要事务的地方@Transcation
