舊版SpringMVC中的控制器引數校驗：

    @ControllerAdvice
    public class ControllerCheckAdvice {
    
    
        private Logger log = LoggerFactory.getLogger(getClass());
    
        @ExceptionHandler(BindException.class)
        public ResponseEntity<Tip> checkRequest(BindException e) {
    
    
            log.
 
info(e.getMessage());
    
            BindingResult bindingResult = e.getBindingResult();
    
            String errorMesssage = "校驗失敗:";
    
            for (FieldError fieldError : bindingResult.getFieldErrors()) {
                errorMesssage += fieldError.getField() + ":" + fieldError.getDefaultMessage
 
() + ";";
            }
    
            Tip tip = new ErrorTip(400, errorMesssage.substring(0, errorMesssage.length() - 1));
            return ResponseEntity.badRequest().body(tip);
        }
    
    }

新版WebFlux異常校驗

    @ControllerAdvice
    public class ControllerCheckAdvice {
    
    
        private
 
 Logger log = LoggerFactory.getLogger(getClass());
    
        @ExceptionHandler(WebExchangeBindException.class)
        public ResponseEntity<Tip> checkRequest(BindException e) {
    
    
            log.info(e.getMessage());
    
            BindingResult bindingResult = e.getBindingResult();
    
            String errorMesssage = "校驗失敗:";
    
            for (FieldError fieldError : bindingResult.getFieldErrors()) {
                errorMesssage += fieldError.getField() + ":" + fieldError.getDefaultMessage() + ";";
            }
    
            Tip tip = new ErrorTip(400, errorMesssage.substring(0, errorMesssage.length() - 1));
            return ResponseEntity.badRequest().body(tip);
        }
    
    }
