Custom validator in hibernate ConstrainedElement

I am writing my own constraint. So I need class name and field name in my validator to run HQL in it.

public class MyValidator implements ConstraintValidator<check, Object> {

    @Autowired
    private MyDaoImpl myDaoImpl;

    @Override
    public void initialize(check uniChk) {

    }

    @Override
    public boolean isValid(Object entity, ConstraintValidatorContext ctx) {
    //Need Class name and field name
        objList = myDaoImpl.getDataByColumnName(classname, fieldname, entity.toString());
        // some condition
        return isValid;
    }

constraint name is @check.

I saw something like ConstrainedElementKind, ConstrainedElement interface. I believe anyhow I can get it using it but couldn't find any example of it. I want to make it generic (no hardcoding of class or variable name ).

What can be the way to get this values?
