Taking into account your comment under the question all you need is HandlerInterceptor.

You need to implement that interface and add it to your configuration, for example:

This interface provides method preHanlde, which has request, response and HandlerMethod. To check if the method is annotated just try this:

HandlerMethod method = (HandlerMethod) handler;
OnlyIfXYZ customAnnotation = method.getMethodAnnotation(OnlyIfXYZ.class);
