Hello Benjamin, sorry I didn't get your answer. I have one banner.jsp page and I need to show this page on home page. PathBasedController returns the path "home" as landing page. after getting home page I need to show banner.jsp . Hope you got it. — kaushik gopu, Aug 18 '21 at 14:23
Please add some code (JSP) of your "home" page (landing page where to include the maintenance banner) or of the "banner" you want to show. Both are required as [example]. Did you try to add [``](https://stackoverflow.com/questions/9110148/include-another-jsp-file) to your "home.jsp" ? — hc_dev, Aug 18 '21 at 14:34

In Spring-MVC you could use and extend the HandlerInterceptor to answer each request with a redirect to your maintenance-banner.jsp.

Add an interceptor to redirect each request

@Override
public void postHandle(HttpServletRequest request,
                       HttpServletResponse response, Object handler,
                       ModelAndView modelAndView) throws Exception { 
    // HttpSession session = request.getSession(); // optional check for a session 
    try {
        response.sendRedirect("maintenance-banner");
        return;
    } catch(Exception e) {
        // some error logging
    }
}

This way you could easily add a check for a date-time-range to only show the banner within the maintenance period.
