Yes, exactly - the spring bridge consists of these two parts. One for
reading avalon style config and the bean post processor for managing the
avalon lifecycle interfaces.
After this is done the bean post processor is still around and will used
on all other beans in the container.
If they implement Avalon interfaces, yes.
Maybe the bean post processor could be turned of or removed after that
the Avalon components are processed? But I'm afraid that it isn't
possible. Lazy loaded beans and beans with other scopes (pooled). Might
need the bean post processor even after the initial load.
I think for reloading and other stuff, you'll need the bean post
processor. But I think we could check, if the bean processed by the post
processor is one coming from the avalon configuration. So we could only
apply the lifecycle interfaces if it is an avalon configured component.
Thinking a little bit more about it, this will create problems for the
sitemap components that I have tried to make configurable both as an
Avalon component and a ordinary Spring bean. Consider the file
generator, it is a poolable component and will probably be served
through some proxy that the Avalon bean post processor adds. But in the
Spring configuration I made it a prototype scoped bean. As it has been
like this for some time it seems like it works, burt I would guess that
it consumes unnecessary resources.
But I really think, if you develop a "plain" spring bean, that you
shouldn't use any avalon interfaces.
Exactly, and I start to think that my suggestion that we should keep the
Avalon configurabillity of sitemap components wasn't such a good idea.
It seem to create more problems than it solves.
I suggest that when Springifiing components, we just remove the Avalon
stuff.
WDYT?
