Using javax.validation validate the date must not be less than 1900-01-01

i have a class which is working as the request payload for my api . I need to validate the one of my field "dateOfBirth". Using the javax.validation.past i am checkking the date is not future date but i also want to validate that the date must not be less than 1900-01-01 .

Is there any way using javax.validation api we can do it?

Class Employee{

 ----
 ---
  @Past(message="date of birth must be less than today")  
  @DateTimeFormate( pattern="yyyy-MM-dd")
  private Date dateOfBirth;

  //constuctor

  //getter & setter

}

You can create your validation logic that specifies that the birthdate be in the past and after your date like so:

public class BirthDateValidator implements ConstraintValidator<BirthDate, LocalDate> {

  private LocalDate OLDEST_ALLOWED_DATE = LocalDate.of(1900, 01, 01);

  @Override
  public boolean isValid(LocalDate date, ConstraintValidatorContext context) {

    LocalDate currentDate = LocalDate.now();

    return currentDate.isAfter(date) && date.isAfter(OLDEST_ALLOWED_DATE);
  }
}

Then you can bind this validation logic to your custom validator interface like so:

@Target(ElementType.FIELD)
@Retention(RetentionPolicy.RUNTIME)
@Constraint(validatedBy = BirthDateValidator.class)
public @interface BirthDate {
  String message() default "Birth Date must be in the past";

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

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

Now you can apply this validator to the field you're interested in using the annotation

The post from https://stackoverflow.com/a/54258098/15541786 is great. I did it in my project and it's working. Just to avoid errors in console, add also to interface

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

So, working example:

@Target(ElementType.FIELD)
@Retention(RUNTIME)
@Constraint(validatedBy = DateValidator.class)
@Documented
public @interface IsAfter{
   String message() default "{message.key}";
   String current();
   Class<?>[] groups() default {};
   Class<? extends Payload>[] payload() default {};
}

You should define custom annotation for this propose. something like bellow: 

@Target(ElementType.FIELD)
@Retention(RUNTIME)
@Constraint(validatedBy = DateValidator.class)
@Documented
public @interface IsAfter{
   String message() default "{message.key}";
   String current();
}

and also define a custom validator like this: 

public class DateValidator implements ConstraintValidator<IsAfter, LocalDate> {

String validDate;

@Override
public void initialize(IsAfter constraintAnnotation) {
    validDate = constraintAnnotation.current();
}

@Override
public boolean isValid(LocalDate date, ConstraintValidatorContext constraintValidatorContext) {
    String[] splitDate = validDate.split("-");
    return date.isAfter(LocalDate.of(Integer.valueOf(splitDate[0]), Integer.valueOf(splitDate[1]), Integer.valueOf(splitDate[2])));
  }
}

and use this annotation: 

@Past(message="date of birth must be less than today")  
@IsAfter(current = "1900-01-01")
@DateTimeFormate( pattern="yyyy-MM-dd")
private Date dateOfBirth;

note: I haven't tested this annotation!
