可以将下面的代理创建器删除。
<bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
<property name="beanNames">
<value>*DAO </value>
</property>
<property name="interceptorNames">
<list>
<value>transactionInterceptor </value>
<!--
此处增加新的Interceptor
-->
</list>
</property>
</bean>
------------------------
可以采用其他的AOP实现,这个特点是每个DAO都必须指定parent为abstractDAOProxyFactoryBean。代码如下：
-------------------------
<bean id="abstractDAOProxyFactoryBean" class="org.springframework.aop.framework.ProxyFactoryBean" abstract="true">
<property name="interceptorNames">
<value>transactionInterceptor</value>
</property>
</bean>
<bean id="accountsDAO" parent="abstractDAOProxyFactoryBean">
<property name="target">

</property>
</bean>
