Answer 1

Generally, your business logic goes in the service layer. Though you can put basic validation rules in your pojos with JSR annotations.

For a Spring MVC app you have controllers, which handle http requests, and a domain layer, which are pojos representing your business models. You often have a persistence layer, or DAO. You might have a service layer as well, for helping with non-trivial logic.

Your comment about database handling doesn't make sense. Business rules are orthogonal to storing data. Your database handling should go in your persistence layer.
