RE: [Springframework-developer] Public references

We use hibernate 2.1 and initially chose Spring for this support and the
transaction demarcation.  The domain objects do encapsulate some
business logic related to behavior that only depends on itself and/or
other domain objects.  We have DAOs and implementations that extend the
Spring Hibernate support for all data access logic.  We also have a
layer of service objects above that which consolidate multiple DAO calls
in a single business operation and to demarcate transactions.  Pretty
standard stuff for a big web app.  Other things the to note are that we
depend upon the OSIV filter anti-pattern  (sorry, I love it) and that we
don't use Spring MVC :-(.

March,

just out of curiosity - what data access strategy this site uses and
does it have a "rich" (with behavior) domain model?

Dmitriy.

You may also include http://eq2players.station.sony.com, arguably the
coolest site to use Spring.  We have hundreds of thousands of users and
serve thousands concurrently.  We're on 1.1.4.

	Hi Cameron,
	=20
	As you're mentioning those two sites so publically ;-) Do you
think we
	   =20

we
 =20

	could include them in our public reference list for Spring?
We're
	   =20

about to
 =20

	collect some references for exposure on the Spring website.
	=20
	Our main problem is that public references in the banking sector
	   =20

(where
 =20

	some
	of the largest Spring deployments are) are usually impossible to
get.
	Therefore, we're particularly grateful for references that we're
	   =20

allowed
 =20

	to
	use on our website!
	=20
	Thanks for your kind words on the quality of our snapshots, BTW
:-)
