I don’t think this is possible, cause a query always returns a List: http://docs.jboss.org/hibernate/orm/3.2/api/org/hibernate/Criteria.html#list()
or in a special case a single element.
There is just no method that could return a map.
So without hacks like overwriting the Session to create a special Criteria which also has a map() method you can’t do what you want.
Just return a list and convert it into a map.
