Best way to get service from different thread
Hi Everyone,
I have been looking through the docs and mailing list but cant find and
answer to this. What is the best way to get an autobuilt service from a
separate thread? I have a quartz job that needs one of my services but im
not sure what i do to get it.
Thanks,
Zack

When there are per-thread services they are there for a reason. They
tend to be rare, and hold data specific to a single request. Remember
that the proxies are completely shareable across threads, the dispatch
to the per-thread instance occurs INSIDE the proxy.
As usual, rather than asking for a specific solution/workaround to a
specific perceived problem, you will get much more utility by
discussing what you are ultimately attempt to do. You'll usually
discover the solution is MUCH simpler than what you naively ask for.

Because the thread might use any number of different services and it would be
nice to be able to just grab them at will from another thread rather than
modifying a constructor each time. I guess I'll just have pass all the
objects. Thanks for the help!

No, not as far as I know - I suppose you could try get access to the
same service registry instance but it's well-hidden for a reason. Why
don't you just pass the required services to the thread at its
construction?

Sorry yea I shouldnt have used quartz as an example. I use job data map to
pass hibernate stuff through in that case but what about a standalone new
thread? I have a service that spawns new tasks in new threads. Is there a
way i can inject something like service resources?

You put the service in JobDataMap and in Job you get the map from
JobExecutionContext.
