Question

我的Spring Boot应用程序中有一个自定义注释，尽管有验证消息，它仍可正常工作......

这是我的自定义注释

@Documented
@Constraint(validatedBy = ReservationValidatorJSON.class)
@Target( { ElementType.METHOD, ElementType.FIELD })
@Retention(RetentionPolicy.RUNTIME)
public @interface ValidReservationJSON {

    String message() default "";
    Class<?>[] groups() default {};
    Class<? extends Payload>[] payload() default {};

    int day();

}

及其验证器

public class ReservationValidatorJSON implements ConstraintValidator<ValidReservationJSON, String> {

    private final Logger logger = LoggerFactory.getLogger(ReservationValidatorJSON.class);

    private int day;

    @Override
    public void initialize(ValidReservationJSON date) {
        day = date.day();

    }

    @Override
    public boolean isValid(String date, ConstraintValidatorContext ctx) {
        SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
        DateTime dateToValidate = null;
        try {
            dateToValidate = new DateTime(sdf.parse(date));
            DateTime now = new DateTime();

            if (dateToValidate != null) {
                return dateToValidate.isBefore(now.plusDays(day));
            }

        } catch (ParseException e) {
        }
        return false;

    }

}

我以这种方式使用这个注释

@ValidReservationJSON(day=31)
private String fromDate;

然后我在我的消息属性中有了这个字段

ValidReservationJSON.fromDate = The beginning date cannot be after {day} days from now

当验证失败时，我会期待像

这样的消息

The beginning date cannot be after 31 days from now

但我一直在

The beginning date cannot be after {day} days from now

Answer 1

尝试此邮件而不是ValidReservationJSON.fromDate = The beginning date cannot be after {1} days from now
