How to get java.util.Map from hibernate query?

I am wondering what is the best way to get map array from hibernate query. Google says to iterate query.list(), and create/put objects i开发者_Go百科nto empty map array.

I guess there would be some elegant and efficient way to do this. Could somebody give me idea?

See Hibernate Documentation - 15.6. The select clause:

You can assign aliases to selected expressions using as:

select max(bodyWeight) as max, min(bodyWeight) as min, count(*) as n
from Cat cat

This is most useful when used together with select new map:

select new map( max(bodyWeight) as max, min(bodyWeight) as min, count(*) as n )
from Cat cat

This query returns a Map from aliases to selected values.
