Betreff: [Springframework-developer] Explicit reference to bean in = parent context There is an interesting feature request in our JIRA: http://opensource.atlassian.com/projects/spring/browse/SPR-166 Basically, a bean should be able to reference a bean of the same name in = the parent context, for example to proxy it. Currently, a reference to the same bean name will lead to a self = reference. I'm not keen on changing this, as there might be valid use = cases for such a configuration. I quite like Damon's suggestion: introduce a "parent" attribute for the = <ref> tag, as alternative to "bean" and "local". Such a reference = explicity refers to a bean in the parent context rather than in the = current one. I've already implemented this: was straightforward to do, with = RuntimeBeanReference having an optional "toParent" flag now. As this is fully backward-compatible and a nice (though probably rarely = used) enhancement, I don't mind including this in 1.0.3. Opinions?

Sorry, I meant to reply and completely forgot about it. I think this is a decent idea, and have been unable to think of any nagative possibilities arising out of it...

This isn't the same thing as loading multiple contexts like in the servlet examples, correct? I take it these are all siblings? If so, the parent/child type of context implies the feature that one context can override beans declared in a child context, or perhaps the other way around? I think in those cases there may be some obscure reasons why a child may want to access the parent bean it overrides. Possibly because of a delegation type relationship. |
