I would agree that's probably not a good idea, but I'm sure I've seen it done..

Personally I think option 2 sounds better.. preferably use an IDE or plugin that can create getters and setters for you and do the validating for you if there are multiple fields with the same validation requirement.  If not then just build in a framework for it, try to prevent duplicating code as much as possible.
