[Springframework-developer] Command framework as interfaces

[Andy D. <an...@ma...>]

Hello all,
  As of my snapshot of spring-rich, the command framework is defined mostly 
via abstract and concrete classes (AbstractCommand, ActionCommand, etc).  
This is all completely functional, but every time I use the command framework 
it just... feels wrong... Of course, there are some interfaces (such as 
Guarded), but I just can't shake the feeling that there ought to be a Command 
or ActionCommand interface.  Sometimes I need to reference a command in my 
code and I can never boil my reference down to an interface... the reference 
almost always becomes "AbstractCommand" - again, this feels wrong.  I know 
that this is really unnecessary from a functional standpoint, but what is the 
consensus on making command/action command interface(s)?  For me, I don't 
have any use cases that would benefit from it - it would benefit me only in 
that I would breath easier about the whole thing.  But still, something in me 
screams, "give me interfaces or give me death!"  Well, not death literally of 
course. :-)
