Hibernate subqueries

TABLE A ( id, type1, type2) id is the primary key
TABLE B (idType1,idType2) where (idType1,idType2) is the union primary key
eg:
A   id  type1 type2
     1 t1 null
     2    null     t2
     3 t1 null
     4    null      t2

B :
    idType1   idType2
       1                2
       1                4
       3                2
       3                4

SELECT
            a.*
FROM
           A a
WHERE  
              a.type1 = 't1'
        and a.id in (
                            SELECT
                                         b.idType2
                            FROM   
                                         B b
                            WHERE
                                        b.idType1 = 1
                         )

Please use Hibernate's Criteria to implement this SQL
       To get the result set directly. Do not search out List<Long> idType2 first as a condition and then do a second search

           Criteria criteria = this.getSession().createCriteria(A.class);

            DetachedCriteria detachedCriteria = DetachedCriteria.forClass(B.class);
            detachedCriteria.setProjection(Projections.projectionList().add(Projections.groupProperty("b.idType2")));
            detachedCriteria.add(Restrictions.eq("b.idType1", 1));

            criteria.add(Subqueries.propertyIn("a.id", detachedCriteria));
            criteria.add(Restrictions.eq("a.type1",“t1”));

            if (criteria.list().size() > 0) {
                return (A) criteria.list().get(0);
            } else {
                return null;
            }


Example:
           Criteria criteria = this.getSession().createCriteria(this.getPersistentClass());

            DetachedCriteria detachedCriteria = DetachedCriteria.forClass(ServiceProvider.class);
            ProjectionList proList4DetachedCriteria = Projections.projectionList();
            proList4DetachedCriteria.add(Projections.groupProperty("id"));
            detachedCriteria.setProjection(proList4DetachedCriteria);

            ProjectionList proList4Criteria = Projections.projectionList();
            proList4Criteria.add(Projections.countDistinct(International.PROP_CODE));
            criteria.setProjection(proList4Criteria);

            // criteria.add(Restrictions.in(International.PROP_ID, new Object[] { 205, 584, 647, 648 }));
            criteria.add(Subqueries.propertyIn(International.PROP_ID, detachedCriteria));
            Object counter = criteria.uniqueResult();
            if (counter != null) {
                return ((Number) counter).intValue();
            }
