RE: [Springframework-developer] purpose of code in Errors.rejectV alue()

[John C. <joh...@sa...>]

Tony,


Thanks for your explanation. It makes a lot more sense now.

 

To be honest, I'm not as familar with the Validator pattern.  
From my recollection of that chapter in the book, I thought
Rod advocated having a separate object that contained all validation logic
that both
the Business Object layer, and the Controller could call.  Better to have
Rod
field that question.

[John Cavacas] That was my understanding as well in regards to the validator
interface from reading the book. But unless I missed something obvious, I
just don't see how that would work, especially from the Business Object
layer side of things. I've been playing around with some ideas as well to
come up with a way to have common "validator plug-ins". I saw a class in
spring that I think is ment for that purpose, but it looks like an
unfinished thought. I think that using the bean framework and maybe a change
in the validator interface, could make that concept a reality, and it's
something that I want to explore.

Thanks again,
John
