Handle org.thymeleaf.exceptions.TemplateInputException - spring-mvc

Question

I have the following controller logic. However, if I navigate to a non-existing page (e.g. /random-page), I end up with a TemplateInputException. How can I catch this and go to the 404 page?
#RequestMapping(value = { "{path:(?!resources|error).*$}", "{path:(?!resources|error).*$}/**" }, headers = "Accept=text/html")
public String index(final HttpServletRequest request) {
try {
String path = (String) request.getAttribute(
HandlerMapping.PATH_WITHIN_HANDLER_MAPPING_ATTRIBUTE);
return path.split("/")[1];
} catch (Exception e) {
log.error("Failed to render the page. {}",e);
return "error/general";
}
}
Thymeleaf seems to be ignoring the ExceptionHandler:
#ExceptionHandler(Exception.class)
public ModelAndView handleAllException(Exception ex) {
ModelAndView model = new ModelAndView("error/generic_error");
model.addObject("errMsg", "this is Exception.class");
return model;
}

My workaround this problem for spring-boot (exception is view with message param):
#Controller
public class ErrorController implements org.springframework.boot.autoconfigure.web.ErrorController {
private static final String ERROR_PATH = "/error";
#Autowired
private ErrorAttributes errorAttributes;
#Override
public String getErrorPath() {
return ERROR_PATH;
}
#RequestMapping(ERROR_PATH)
public String error(HttpServletRequest request, Model model) {
Map<String, Object> errorMap = errorAttributes.getErrorAttributes(new ServletRequestAttributes(request), false);
String exception = (String) errorMap.get("exception");
if (exception != null && exception.contains("TemplateInputException")) {
errorMap.put("message", "Неверный запрос");
}
model.addAllAttributes(errorMap);
return "exception";
}
}
