Default return error for white label erorr - spring

Question

I have this controller which is open when user is redirected.
#Controller()
public class RedirectController {
#RequestMapping(method = RequestMethod.GET, value = "/redirect")
#ResponseBody
public String handleRedirectMessage(HttpServletRequest request) throws Exception {
......
}
}
But when the match is not found I get Whitelabel Error Page. Is there some way to set default handler which is by default open when path is not correct?

You need add following property:
server.error.whitelabel.enabled=false
And implement org.springframework.boot.web.servlet.error.ErrorController interface and overrides its getErrorPath() to return a custom path to call when an error occurred:
#Controller
public class MyErrorController implements ErrorController {
#RequestMapping("/error")
public String handleError() {
//do something like logging
return "error";
}
#Override
public String getErrorPath() {
return "/error";
}
}
After that add error page for path "/error" Thymeleaf error.html.
Also you could add pager for different errors:
#RequestMapping("/error")
public String handleError(HttpServletRequest request) {
Object status = request.getAttribute(RequestDispatcher.ERROR_STATUS_CODE);
if (status != null) {
Integer statusCode = Integer.valueOf(status.toString());
if(statusCode == HttpStatus.NOT_FOUND.value()) {
return "error-404";
}
else if(statusCode == HttpStatus.INTERNAL_SERVER_ERROR.value()) {
return "error-500";
}
}
return "error";
}
