A controller (as any spring bean) has a scope. At best your controllers should be of scope singleton. In that case it is very much like servlets, and: they are created only once, during the application context startup (and destroyed when the context is destroyed) you should not use any instance variables (as this is not thread-safe) If your controller scope is request or session, then you can have instance variables, and an instance of the controller is created on each new request/session.
