Hi Eirik
I totally forgot, I looked at the code and realized I did something
there to support CXF Features - the fact the interceptors are added per
request is the unfortunate side-effect that in 2.0 API WebTargets are
spawned per request, so obviously it was not done by design. To be
honest I did not spend much time on it.
Right so it nearly works, and worth investigating further how to avoid
adding duplicate interceptors.
I don't think adding interceptors directly will work because the client
will no idea if it is the in or out interceptor. Feature will work

Sergey,
Our observation (with 3.0.3 I think) was that the feature was not ignored,
but instead initialized once per request. Which added new interceptors to
the WebClient on every request. Not sure I understand the intention behind
this design.
I think I just assumed that I could use Interceptors for JAX-RS clients
just like JAX-WS.
We could and probably will rewrite these to JAX-RS filters, but it would of
course be even sweeter if we could simply reuse the logging interceptors we
currently use for our SOAP services.
Cheers,
Eirik.

Hi
It is not possible to register CXF specific Feature or Interceptor
with JAX-RS 2.0 Client API.
When you do "client.register(new MyLoggingFeature())", assuming it is CXF
Feature, then it will be currently ignored.
I wonder if it might make sense to create some JAX-RS 2.0 FeatureWrapper
which can wrap an arbitrary CXF Feature...I'll try to experiment with it...

Hello,
Is the CXF implementation of the JAX-RS 2.0 client API designed to allow
Interceptors to be configured on Clients? If so, how should this be done?
Say we have a Client built like this:
Client client = ClientBuilder.newClient();
and we want to configure Logging[In/Out]Interceptors of this client. (Just
as an example).
First I tried in various ways to get an Endpoint out of the client, but
failed at that.
Then, after looking through the implementation classes of
Client/WebTarget,
I discovered that you can register CXF Features on a Client using
something
like
client.register(new MyLoggingFeature());
However, with this setup MyLoggingFeature.initialize(InterceptorProvider
ip, Bus bus) is called _once per request_.
Not exactly what I wanted since it lead to the interceptor chains being
filled up with duplicate LoggingInterceptors.
I might perhaps have misunderstood the lifecycle of Clients and/or
WebTargets. Should be ok to reuse a JAX-RS 2.0 Client, right?
Can someone please enlighten me? Did I perhaps miss some relevant
documentation?
Cheers,
Eirik.
