Tom Quarendon created ARIES-1867: ------------------------------------ Summary: ContainerResponseFilter not fired for SSE endpoint Key: ARIES-1867 URL: https://issues.apache.org/jira/browse/ARIES-1867 Project: Aries Issue Type: Bug Components: jax-rs-whiteboard Reporter: Tom Quarendon
I have a resource class such as the following: {code:java} @Path("events") @JaxrsResource public class EventsResource { private Sse sse; private SseBroadcaster eventBroadcaster; @Context public void setSse(Sse sse) { this.sse = sse; this.eventBroadcaster = sse.newBroadcaster(); } @GET @Produces(MediaType.SERVER_SENT_EVENTS) public void suscribeToEvents(@Context SseEventSink eventSink) { eventBroadcaster.register(eventSink); } } {code} In addition, I have a CORS filter: {code:java} @Component(immediate=true) @Provider @JaxrsExtension public class CORSFilter implements ContainerResponseFilter { @Override public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext) throws IOException { System.out.println("CORSFilter for "+requestContext.getUriInfo().getPath()); MultivaluedMap<String, Object> headers = responseContext.getHeaders(); headers.add("Access-Control-Allow-Origin", requestContext.getHeaderString("Origin")); ... {code} The CORS filter gets fired on all requests as I expect, _except_ for ones to the EventResource.subscribeToEvents method. Hence browsers complain when receiving SSE events. This used to work fine with jersey as the JAXRS implementation. CORS filter got called for the EventsResource.subscribeToEvents call. I've no idea whether this is a jaxrs-whiteboard level issue, or a CXF level issue. I will try and come up with a plain CXF test of the same thing for comparison. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
