<Spring> Exception

1. runtimeException  을 상속받은 exceiption class 생성

@Getter
public class CustomValidationException extends RuntimeException {
    private Map<String, String> errorMap;

    public CustomValidationException(String message, Map<String, String> errorMap) {
        super(message);
        this.errorMap = errorMap;
    }
}

 

2. ExceiptionAdvice class 생성

@RestControllerAdvice
public class ExceptionAdvice {

    @ExceptionHandler(CustomValidationException.class)
    public ResponseEntity<?> validationError(CustomValidationException e) {
        return ResponseEntity.badRequest()
                .body(new CMRespDto<>(HttpStatus.BAD_REQUEST.value(), "Validation Error", e.getErrorMap()));
    }
}

@ RestControllerAdvice, ExceiptionHandler(exception class.class) 받고

return 값으로 bad request !
