Java 是否可以对两个不同的类使用类级自定义约束注释

我有下一个约束注释：

@Target({TYPE, ANNOTATION_TYPE})
@Retention(RUNTIME)
@Constraint(validatedBy = PhoneOrEmailPresentedValidator.class)
@Documented
public @interface PhoneOrEmailPresented {

    String message() default "Either phone or email should be presented";

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};
}

public class PhoneOrEmailPresentedValidator implements ConstraintValidator<PhoneOrEmailPresented, RequestDto> {

    @Override
    public boolean isValid(RequestDto value, ConstraintValidatorContext context) {
        String email = value.getEmail();
        String phone = value.getPhone();

        return (email != null && !email.isEmpty()) ||
               (phone != null && !phone.isEmpty());
    }

    @Override
    public void initialize(PhoneOrEmailPresented constraintAnnotation) {
        // NOP
    }
}

@Target（{TYPE，ANNOTATION\u TYPE}）
@保留（运行时）
@约束（validatedBy=PhoneOrEmailPresentedValidator.class）
@记录
public@interface PhoneOrEmailPresented{
String message（）默认值“应显示电话或电子邮件”；
类[]组（）默认值{}；
类由于在验证API中找不到任何方法，因此使用反射解决了问题（借助类
org.apache.commons.lang3.reflect.FieldUtils
，Java也可以这样做）：

        String email, phone;

        try {
            Field emailField = FieldUtils.getField(value.getClass(), "email", true);
            Field phoneField = FieldUtils.getField(value.getClass(), "phone", true);
            email = (String) emailField.get(value);
            phone = (String) phoneField.get(value);
        } catch (IllegalAccessException e) {
            e.printStackTrace();
            return false;
        }
