Re: [Springframework-developer] customized BeanFactory

[Bing R. <br...@cc...>]

Thanks Steve. Unfortunately the way that the =
PropertyPlaceHolderBeanfactory
Works does not meet my need. What I'd like to have is a repeatable
interpretation of an injected value each time the bean (a prototype) is
created, rather than the one-time post-processing. What I'm doing is
actually part of my effort to replace the bean management facility of =
JSF
with what I'm doing on top of Spring (see http://jacn.sf.net). I need =
the
ability to re-evaluate a JSF value-binding expression such as
#{param.user_name}, which binds to a parameter in the http request, =
which of
course is different every time a new request comes in.=20

Any insight into this?

Bing,

You can implement a BeanFactoryPostProcessor to do that. Have a look =20
at the code of PropertyPlaceholderConfigurer. This class inspects =20
bean definitions and replaces ${key} with property values loaded from =20
property files. BeanFactoryPostProcessors are recognized by the bean =20
factory and applied automatically.
