Re: [Springframework-developer] Spring 1.2 RC2 and Acegi Security

[Juergen H. <ju...@in...>]

Yes, there are essentially these two options: either require Spring 1.2 as
of the next Acegi release (which should probably be called 0.9 then), or
copy the old PathMatcher over. In the former case, Acegi should follow the
new Spring pattern there: components that need path-matching functionality
receive a PathMatcher implementation through dependency injection, using an
AntPathMatcher as default.

BTW, it would be good to unify the codebases in the mid term, for example
moving some of the generic Acegi utility stuff over to the main Spring
codebase. IMO, we should do this for Acegi Security 1.0 at the latest, with
Acegi concentrating on the actual security support only. In any case, I
guess it's inevitable to depend on a specific Spring release level at some
point.

I should note that I ran across this earlier and posted a patch to the Acegi
developer's list (see
http://article.gmane.org/gmane.comp.java.springframework.acegisecurity.devel
/864 ).
I didn't officially submit this patch, as it breaks backward compatibility
with Spring (it will only run with the very latest Spring).  If a goal of
the
Acegi project is to maintain such compability, it will probably either want
to remove the dependency (by copying the code into the Acegi project), or
use
reflection or other technique at runtime to dynamically adapt to the Spring
version.
