There's a couple ways to do it. The first and most straight forward is to use a restriction.

public List<Friend> listFriends(String userName) {
    return (List<Friend>) sessionFactory.getCurrentSession()
        .createCriteria(Friend.class)
        .add(Restrictions.eq("userName", userName) )
        .list();
}

Another way would be to use an example.

public List<Friend> listFriends(String userName) {
    Friend friend = new Friend();
    friend.setUserName(userName);

    return (List<Friend>) sessionFactory.getCurrentSession()
        .createCriteria(Friend.class)
        .add(Example.create(friend))
        .list();
}
