Adding Spring bean using annotations : placing it & initializing properties values

I've gle开发者_Python百科aned that adding the context:component-scan will enable adding any jar with bean annotated as @Bean to the spring configuration, but , while getting lost in the Framework reference...

• How can I add that bean as interceptor on specific channel?
• How can bean properties be initialized if there's no element in the context.xml to specify them ? (such as String properties)

Thanks to all .... (it's spring framework 3.0.)

You need to use the @Value annotation to inject the value from a property coming from a property file or a -Dproperty
