How to combine pagination with a criteria query in Spring Data JPA?

Question

I use PagingAndSortingRepository and findAll(Pageable pageable) method to paging my data. I think that there is no way to provide any condition. For example sometime I want sele

For Pagination you need 2 methods like getCount(Pageable pageable) and findAll(Pageable pageable)

Utilizing this functionality in Hibernate, however, is trivial. If you have any HQL query you can simply do this:

public Long getCount(Pageable pageable) {
    Query q = session.createQuery("Select count(t) From TableClass  t where t.city = 'NY'");
    Long cnt = (Long) q.uniqueResult();
    return cnt;
}

public List findAll(Pageable pageable) {
     Query q = session.createQuery("From TableClass  t where t.city = 'NY'");
     q.setFirstResult(start);
     q.setMaxResults(length);
     List tableClasslist = q.list();
     return tableClasslist;
}

Likewise, if you have a Criteria query, it's effectively the same thing:

public Long getCount(Pageable pageable) {
    Criteria c = session.createCriteria(TableClass.class);
    c.setProjection(Projections.rowCount()); 
    Long cnt = (Long) c.uniqueResult();
    return cnt;
}

public List findAll(Pageable pageable) {
    Criteria c = session.createCriteria(TableClass.class);
    c.setParameter("city","NY");
    c.setFirstResult(start);
    c.setMaxResults(length);
    List tableClasslist = c.list();
    return tableClasslist ;
}
