Create a java class which extends HandlerInterceptorAdapter.

You can override preHandle and postHandle methods as per your requirement.

public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
System.out.println("In Prehandle");
}
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception {
    System.out.println("In postHandle");
}
