Hibernate, select by id or unique column

You need to use the query cache to avoid the database access when querying by name.

I am using hibernate for Java, and I want to be able to select users by id or by name from the database.
Nice thing about Hibernate is that it caches the result by id, but I seem to be unable to make it cache by name.
static Session openSession = Factory.openSession(); public static User GetUser(int Id) { return (User) openSession.get(User.class, new Integer(Id)); } public static User GetUser( String Name ){ return (User) openSession.createCriteria( User.class ). add( Restrictions.eq("username", Name) ). uniqueResult(); }
If I use GetUser(1) many times, hibernate will only show that it executed the first time.
But every time I use GetUser("user1"), hibernate shows that it is executing a new query to database.
What would be the best way to have the string identifier be cached also?
