public abstract class InterceptableServlet
extends HttpServlet

Estende la classe astratta HttpServlet per fornire supporto al meccanismo degli interceptor. È possibile applicare gli interceptor in due modi:

• Applicando l'annotazione associata all'interceptor desiderato sul metodo "doX" desiderato
• Applicando l'annotazione associata all'interceptor desiderato sulla classe interceptor. In questo modo, l'interceptor sarà applicato a tutti i metodi "doX" sovrascritti.
