Resteasy client : How to set Context Params - jax-rs

Question

I'm using Resteasy client to run test cases for my Service. In application We set context Params in a session check filter,(which implements ContainerRequestFilter). I'm trying to set the same, in Resteasy client, using by adding a ClientRequestFilter implementation, but the property is not recognized, in the service call.
//Resteasy client calling logic
ResteasyClient resteasyClient = new ResteasyClientBuilder().build();
resteasyClient.register(new MyClientRequestFilter());
resteasyClient.target("http://localhost:" + port + "/myPath").request()
.post(Entity.json(authorization_reqParams)).readEntity(String.class));
//filter
public class MyClientRequestFilter implements ClientRequestFilter
{
#Override
public void filter(ClientRequestContext requestContext) throws IOException
{
requestContext.setProperty("CUSTOMER_ATTRIBUTE", "myCustomValue");
}
}
//Rest service method
#POST
#Path("/myPath")
#Produces(MediaType.APPLICATION_JSON)
#Consumes(MediaType.APPLICATION_JSON)
public Response subpartner(Authorization_ReqParams authorizationReqParams, #Context HttpHeaders headers,
#Context HttpServletRequest request, #Context HttpServletResponse response)
{
String myAttribute= request.getAttribute("CUSTOMER_ATTRIBUTE");
//myAttribute is returned as null always
//additional logic
}
I'm able to set&get Header paramets with the same implementation, but Request param is always read as null.
How can I set the request context params ?

In MyClientRequestFilter you add a propery to the request object. What you really want is to send a header instead.
Try this instead:
#Override
public void filter(ClientRequestContext requestContext) {
MultivaluedMap<String, Object> headers = requestContext.getHeaders();
headers.add("CUSTOMER_ATTRIBUTE", "myCustomValue");
}
And read it like this:
#POST
#Path("/myPath")
#Produces(MediaType.APPLICATION_JSON)
#Consumes(MediaType.APPLICATION_JSON)
public Response subpartner(Authorization_ReqParams authorizationReqParams, #Context HttpHeaders headers,
#Context HttpServletRequest request, #Context HttpServletResponse response)
{
String myAttribute= headers.getRequestHeader("CUSTOMER_ATTRIBUTE");
//additional logic
}
