Statically access MessageContext
Hi all.
I have a spring managed CXF application where CXF resources simply forward
calls to spring services.
Also I've set up CXF implementation of OAuth2 framework.
Now my problem is that I want to get the credentials of user from my spring
services, i.e. somehow I need statically access MessageContext object. The
question is how to do that?
Thanks in advance.

Then I guess you can try
new MessageContextImpl(PhaseInterceptorChain.getCurrentMessage());
and proceed from there by working with OAuthContextUtils
or
OAuthContext context =
PhaseInterceptorChain.getCurrentMessage().getContent(OAuthContext.class)
and work with the OAuth context directly

We use spring configuration, and can't make our services per request.
The stack is as follows:
Web->JAX-RS Resource->Spring Service (Business Logic)->DB Layer->DB
JAX-RS resources effectively get access to valid MessageContext by
implementing
@Context
void setMessageContext(MessageContext mc)
The problem is, I don't need it inside my resource methods as they just
forward calls to appropriate business logic services.
Our business services are singletons and this can't be changed for many
reasons. To implement security checks inside them (which are also business
related checks) we need data from MessageContext (well, we'll wrap it in
something fancy and less transport dependent, we need only clinetId and
userSubject).
Currently, I'm trying to build a Utility class, which will be used by
business services, which gets that MessageContext data from some static
place.
Hope I've explained properly, if not I can post some diagrams.

I guess you need to use
http://svn.apache.org/repos/asf/cxf/trunk/rt/rs/security/oauth-parent/oauth2/src/main/java/org/apache/cxf/rs/security/oauth2/utils/OAuthContextUtils.java
It depends on the injected MessageContext.
Actually, you said it was not possible to inject it ? Given that you
mentioned a per-request (Spring) scope, may be this can help:

Thanks Sergey.
from Daniel's suggestion I didn't find a way to get OAuth2 properties like
clientId, roles, etc. Do you know how to get them?

As far as CXF is concerned, it clears its ThreadLocals once the current
invocation is complete,

Thank you very much Daniel.
One more question, I've digged the codes and noticed that CXF relies on
Java's standard ThreadLocals, which means, request scope may not be the same
as thread scope, as tomcat uses a threadpool.
How CXF deals with that problem to make sure contexts are not messed up?

The easiest is likely to call PhaseInterceptorChain.getCurrentMessage() to grab the internal CXF message and pull the various properties out of there.
