如何在hibernate中使用条件对列表进行排序

Question

I am new to Spring3 and Hibernate the following code works great but I am trying to find a way to have my list returned in sort order by the date field. Can someone please show me how to add sort to this code

// To get list of all articles
@SuppressWarnings("unchecked")
public List<Friend> listFriends(String rUser) 
{
   Friend friend = new Friend();
    friend.setUsername(rUser);

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

Answer 1

.addOrder( Order.desc("date") )

Answer 2

Either have the database do it or Java, your choice. Here's how to do it in Java:

List<Friend> friends = sessionFactory.getCurrentSession()
       .createCriteria(Friend.class)
        .add(Example.create(friend))
        .list();
Collections.sort(friends); 

return friends;
