Spring3,Hibernate; 我该如何使用HibernateTemplate

Question

我试图更改以下代码使用:HibernateTemplate但不能正常工作

public List<Friend> listFriends(String rUser) 
{
    hibernateTemplate = new HibernateTemplate(sessionFactory);

    Friend friend = new Friend();
        friend.setUsername(rUser);

    // This is the old code that worked!
            return (List<Friend>) sessionFactory.getCurrentSession()
            .createCriteria(Friend.class)
            .add(Example.create(friend))
            .list();

        // This IS THE NEW CODE THAT I CANT GET TO BUILD?
            return (List<Friend>) hibernateTemplate.createCriteria(Friend.class)
            .add(Example.create(friend))
            .list();
}

Answer 1

Friend friend = new Friend();
    friend.setUsername(rUser);

return (List<Friend>) hibernateTemplate.findByCriteria(
        DetachedCriteria.forClass(Friend.class)
        .add(Example.create(friend)));

要么

Friend friend = new Friend();
    friend.setUsername(rUser);

return (List<Friend>) hibernateTemplate.findByExample(friend);

要么

return (List<Friend>) hibernateTemplate.findByCriteria(
        DetachedCriteria.forClass(Friend.class)
        .add(Restrictions.eq("username", rUser)));
