How to handle all not handled exceptions in #ControllerAdvice? - exception

Question

I use this exception handler to handle some specific exceptions in my Spring boot application (REST API):
#ControllerAdvice
class GlobalExceptionHandler {
#ExceptionHandler(NotFoundException.class)
#ResponseStatus(HttpStatus.NOT_FOUND)
public
#ResponseBody
ResponseMessage notFound(NotFoundException ex) {
return new NotFoundResponseMessage(ex.getMessage());
}
#ResponseStatus(value = HttpStatus.UNSUPPORTED_MEDIA_TYPE)
#ExceptionHandler(HttpMediaTypeNotSupportedException.class)
public
#ResponseBody
ResponseMessage unsupportedMediaType(HttpMediaTypeNotSupportedException ex) {
return new UnsupportedMediaTypeResponseMessage(ex.getMessage());
}
#ExceptionHandler(UnauthorizedException.class)
#ResponseStatus(HttpStatus.UNAUTHORIZED)
public
#ResponseBody
ResponseMessage unauthorized(UnauthorizedException ex) {
return new UnauthorizedResponseMessage(ex.getMessage());
}
#ExceptionHandler(HttpRequestMethodNotSupportedException.class)
#ResponseStatus(HttpStatus.METHOD_NOT_ALLOWED)
public
#ResponseBody
ResponseMessage methodNotAllowed(HttpRequestMethodNotSupportedException ex) {
return new MethodNotAllowedResponseMessage(ex.getMessage());
}
#ExceptionHandler(ForbiddenException.class)
#ResponseStatus(HttpStatus.FORBIDDEN)
public
#ResponseBody
ResponseMessage forbidden(ForbiddenException ex) {
return new ForbiddenResponseMessage(ex.getMessage());
}
}
and I would like to handle all the others exceptions with one "global" handling method. But I need to get HTTP status code in this method to process error message etc.
Question
Is there some way how to redirect all non-handled exceptions into one particular method? How can I do it?

See the docs:
Any Spring bean declared in the DispatcherServlet’s application
context that implements HandlerExceptionResolver will be used to
intercept and process any exception raised in the MVC system and not
handled by a Controller.
public interface HandlerExceptionResolver {
ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex);
}
