Hibernate setMaxResults paging

Question

如果我没有设置setFirstResult(-)并每次都递归调用criteria.setmaxresults(10) ，它将自动从数据库中获取接下来的10个项目吗？

Answer 1

No. You have to use criteria.setFirstResult(0) and page through yourself, something like this:

public List getCarters(final int firstResult, final int maxResults) {

    final Criteria criteria = sessionFactory.getCurrentSession()
                      .createCriteria(SomePersistentClass.class);
                      .add(Restrictions.eq("name", "Carter"))
    criteria.setFirstResult(firstResult);
    criteria.setMaxResults(maxResults);

    return criteria.list();
}

Answer 2

Of course, no. Criteria grabs data from database only when you call .list() or .uniqueResult()
