@GroupSequenceProvider and group is a superset

问题

Simple class Person.class

class Person {

@NotNull(groups = {PartlyCheck.class})
private String name;

@NotNull(groups = {FullCheck.class})
private String adress;

private boolean isFullCheck;

}

Check interfaces

public interface PartlyCheck{}
public interface FullCheck extends PartlyCheck{}

I use two approach:

    if(person.isFullCheck) {

      validator.validate(person, FullCheck.class);

    else {

       validator.validate(person, PartlyCheck.class);
  }

1.

If isFullCheck=true used both checks (FullCheck.class and PartlyCheck.class)

If isFullCheck=false used only PartlyCheck.class.

It is an understandable behavior.

    @GroupSequenceProvider(PersonGroupSequenceProvider.class)

    @Override
    public List<Class<?>> getValidationGroups(Person person) {                

       List<Class<?>> defaultGroupSequence = new ArrayList<>();
       defaultGroupSequence.add(Person.class);                    


        if (person.isFullCheck) {                                
            defaultGroupSequence.add(FullCheck.class);
        } else {                                
            defaultGroupSequence.add(PartlyCheck.class);
        }       


       return defaultGroupSequence;
   }

1. In the second case, I added @GroupSequenceProvider(PersonGroupSequenceProvider.class).

If isFullCheck=true used only FullCheck.class.

Why extends is not considered for this case?

If isFullCheck=false used only PartlyCheck.class.
