why 'value' for interceptorNames instead of 'ref'

[Karnati Sudhakar]

Hi All,

I just started learning spring framework from the book spring in Action 2nd edition.

I have a doubt: why we use value attribute to set the interceptorNames proeprty. why not ref attribute because it is actually a reference to another bean in the spring container itself..

    <bean id="audienceAdvisor" class="org.springframework.aop.support.DefaultPointcutAdvisor">
        <property name="advice" ref="audienceAdvice"/>
        <property name="pointcut" ref="performancePointCut"/>
    </bean>

    <bean id="kenny" class="org.springframework.aop.framework.ProxyFactoryBean">
        <property name="target" ref="kennytarget" />
        <property name="interceptorNames" value="audienceAdvisor"/>
        <property name="proxyInterfaces" value="com.springinaction.springidol.Performer"/>
    </bean>

Here in the above code for the property interceptorNames we use value attribute to set audienceAdvisor bean..

Can any one explain me??

Spring documentation says : The names are bean names in the current factory, including bean names from ancestor factories. You can't mention bean references here since doing so would result in the ProxyFactoryBean ignoring the singleton setting of the advice.
