Question

I have a spring MVC application, how can I return a list of users and limit the results?

My UserDao looks like:

public List<User> getUsers(int limit) {
  return super.getHibernateTemplate()????
}

I’m assuming you’re doing this for purposes of paging.

You can create a Query and use setMaxResults and setFirstResult:

public List<User> getUsers(int limit)
{
    Query q = getHibernateTemplate().getSession().createQuery("from User");
    q.setFirstResult(0); // modify this to adjust paging
    q.setMaxResults(limit);
    return (List<User>) q.list();
}

Alternatively, use a HibernateCallback (this is probably the best method, although it’s wordier):

    return getHibernateTemplate().executeFind(new HibernateCallback() {
        public Object doInHibernate(Session session) throws HibernateException, SQLException {
            Query q = session.createQuery("from User");
            q.setMaxResults(limit);
            return q.list();
        }
    });

Which will additionally take care of exception translation for you.
