16.5. Dynamic association fetching

You can specify association fetching semantics at runtime using setFetchMode(). 
List cats = sess.createCriteria(Cat.class)
    .add( Restrictions.like("name", "Fritz%") )
    .setFetchMode("mate", FetchMode.EAGER)
    .setFetchMode("kittens", FetchMode.EAGER)
    .list();
This query will fetch both mate and kittens by outer join. See Section 20.1, “Fetching strategies” for more information.
