Re: [Springframework-developer] Acegi Security's ContextHolder replaced by SecurityContext

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

InheritableThreadLocal is a good idea for thread-bound context that should
actually be inherited. Hence, I've changed Spring's LocaleContextHolder to
use an InheritableThreadLocal.

Subject: [Springframework-developer] Acegi Security's ContextHolder
replaced by SecurityContext


Pursuant to Juergen's recommendation
(http://article.gmane.org/gmane.comp.java.springframework.devel/8290),
Acegi Security CVS has now had its ContextHolder and related classes
removed. This functionality has been replaced by SecurityContext, which
is an InheritableThreadLocal that provides a single getter/setter pair
for Authentication.

This is a significant change for end users, but offers a number of benefits:

- Consistency with Spring core's use of a concrete ThreadLocal per
functional area
- SecurityContext is strictly typed (which eliminates the need for casting)
- Simplified configuration as no need to specify a Context
implementation for HttpSessionContextIntegrationFilter
- InheritableThreadLocal used instead of ThreadLocal to simplify rich
client usage (see http://forum.springframework.org/viewtopic.php?t=5004)
- Elimination of handling the extra Context layer means less end user
code is required

Unit tests pass and I've updated the upgrade-080-090.txt in some detail.
The reference guide has also been updated.

It would be appreciated if developers could try the latest CVS with
their applications and report any difficulties. General feedback on this
change is also welcome.

Cheers
Ben
