RestController will add ResponseBody annotation which automatically converts response to json, which won't work with thymeleaf, as it needs a string response

private boolean process(HttpServletRequest request, HttpServletResponse response)
        throws ServletException {
    
    try {

        // This prevents triggering engine executions for resource URLs
        if (request.getRequestURI().startsWith("/css") ||
                request.getRequestURI().startsWith("/images") ||
                request.getRequestURI().startsWith("/favicon")) {
            return false;
        }

        
        /*
         * Query controller/URL mapping and obtain the controller
         * that will process the request. If no controller is available,
         * return false and let other filters/servlets process the request.
         */
        IGTVGController controller = this.application.resolveControllerForRequest(request);
        if (controller == null) {
            return false;
        }

        /*
         * Obtain the TemplateEngine instance.
         */
        ITemplateEngine templateEngine = this.application.getTemplateEngine();

        /*
         * Write the response headers
         */
        response.setContentType("text/html;charset=UTF-8");
        response.setHeader("Pragma", "no-cache");
        response.setHeader("Cache-Control", "no-cache");
        response.setDateHeader("Expires", 0);

        /*
         * Execute the controller and process view template,
         * writing the results to the response writer. 
         */
        controller.process(
                request, response, this.servletContext, templateEngine);
        
        return true;
        
    } catch (Exception e) {
        try {
            response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR);
        } catch (final IOException ignored) {
            // Just ignore this
        }
        throw new ServletException(e);
    }
    
}
