hibernate验证器的注释,用于将来至少24小时的日期

Question

我知道存在注释@Future.

如果我使用此注释注释字段

@Future
private Date date;

日期必须在将来意味着在当前时刻之后.

现在我需要在当前时刻之后至少24小时验证该日期.
我该怎么做？

Answer 1

AfterTomorrow.java:

@Target({ FIELD, METHOD, PARAMETER })
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy = AfterTomorrowValidator.class)
@Documented
public @interface AfterTomorrow {
    String message() default "{AfterTomorrow.message}";
    Class<?>[] groups() default {};
    Class<? extends Payload>[] payload() default {};
}

AfterTomorrowValidator.java:

public class AfterTomorrowValidator 
             implements ConstraintValidator<AfterTomorrow, Date> {
    public final void initialize(final AfterTomorrow annotation) {}

    public final boolean isValid(final Date value,
                                 final ConstraintValidatorContext context) {
        Calendar c = Calendar.getInstance(); 
        c.setTime(value); 
        c.add(Calendar.DATE, 1);
        return value.after(c.getTime());
    }
}

此外,您可以添加默认AfterTomorrow.message邮件ValidationMessages.properties

最后,注释你的领域:

@AfterTomorrow
private Date date;
