Question about Request and Session with CXF, JAX-RS webservice

Question

I have a webservice set up using CXF, JAX-RS and Spring. I have the following method:

@GET
@Path("/getPayload")
@Produces("application/XML")
public Response makePayload(){
    Payload payload = new Payload();
    payload.setUsersOnline(new Long(200));

    return Response.ok().entity(payload).build();
}

How can I get access to the HttpRequest object in my makePayload()?

Will a call to this method generate a Session, and if so, can I get a handle to it and will that session be persistent for all subsequent requests from the same client?

Answer 1

@Context can be used to obtain contextual Java types related to the request or response:

@GET
@Path("/getPayload")
@Produces("application/XML")
public Response makePayload(@Context Request request) {
    //...
}
