import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.context.request.NativeWebRequest;

@ControllerAdvice
public class FrameControllerAdvice {
    protected static Logger logger = Logger.getLogger(FrameControllerAdvice.class);

    @ExceptionHandler(Exception.class)
    //@ResponseStatus(HttpStatus.BAD_REQUEST)
    public ResponseEntity<String> processUnauthenticatedException(NativeWebRequest request,Exception e) {
        logger.error(e.getMessage());
        e.printStackTrace();
        return new ResponseEntity<String>(HttpStatus.INTERNAL_SERVER_ERROR);
    }
}
