[Springframework-developer] Spring Enhancement

[Rob B. <rob...@ve...>]

Spring now provides the ability to instantiate an object using either a
JavaBean no arg constructor, or any normal Java constructor.  But it does
not support calling methods.

Also, Spring requires that a class implement the InitializingBean interface
if it needs to perform some "setup" work after the setters have all been
called.  This means that any class that has this need is tied to the
Springframework.

What if the ability to call any arbitrary method was added to Spring?  Then
users could call "afterPropertiesSet" to do "setup" work without having to
implement the InitializingBean interface.  Ideally method calls could be in
any order along with calls to setters.  Spring would then call each in
order.  Thus, allowing some setters to be called, then some methods, then
more setters if necessary.  If this is not possible, then methods should be
called after setters.

This would allow complete decoupling of classes from Spring.  The
InitializingBean & BeanFactoryAware interfaces would no longer be needed
(although could remain for backwards compatibility).  This would be very
useful when contributing code to other projects that do not want to have a
dependency on Spring.  Also, it would allow virtually any class used by
/developed for  another IOC framework / lightweight container to be used in
Spring.

Thoughts?
