----------------------------------------
Assignee: Federico Mariani
> CXF RS Rest service loses content-type with stream caching enabled
> ------------------------------------------------------------------
>
> Key: CAMEL-23249
> URL: https://issues.apache.org/jira/browse/CAMEL-23249
> Project: Camel
> Issue Type: Bug
> Components: camel-cxfrs
> Affects Versions: 4.14.5
> Reporter: Dave Riseley
> Assignee: Federico Mariani
> Priority: Minor
>
> When Camel is used to host a CXF JaxRS rest service and stream caching is
> enabled, the content-type is lost from the jaxrs Response object.
> This has happened since CAMEL-22414 implemented support for stream caching
> jakarta.ws.rs.core.Response objects.
> This can be demonstrated with the following test:
> {code:java}
> @Autowired
> ProducerTemplate producerTemplate;
> @Configuration
> static class TestConfig {
> @Bean
> SpringJAXRSServerFactoryBean restServer(Bus bus) {
> SpringJAXRSServerFactoryBean restServer = new
> SpringJAXRSServerFactoryBean();
> restServer.setBus(bus);
> restServer.setAddress("http://localhost:8001/rs";);
> restServer.setServiceClass(EchoService.class);
> return restServer;
> }
> @Bean
> EchoService echoService() {
> return new EchoServiceImpl();
> }
> @Bean
> RoutesBuilder echoRoute() {
> return new RouteBuilder() {
> @Override
> public void configure() throws Exception {
> from("cxfrs:bean:restServer")
> .streamCache(true)
> .bean(EchoService.class)
> .log(LoggingLevel.INFO, "Logging body: ${body}");
> }
> };
> }
> }
> private interface EchoService {
> @GET
> @Path("/echoVariable")
> public Response echoVariable(@QueryParam("say") String say);
> }
> private static class EchoServiceImpl implements EchoService {
> @Override
> public Response echoVariable(String say) {
> return Response
> .status(Status.OK)
> .type(MediaType.APPLICATION_JSON)
> .entity("{ \"message\":\""+ say +"\" }")
> .build();
> }
> }
> @Test
> void testEchoVariable() {
> Exchange responseExchange =
> producerTemplate.send("http://localhost:8001/rs/echoVariable?throwExceptionOnFailure=false&say=hello";,
> e -> {});
> assertNull(responseExchange.getException());
> assertEquals(200,
> responseExchange.getMessage().getHeader(Exchange.HTTP_RESPONSE_CODE,
> Integer.class));
> assertEquals("application/json",
> responseExchange.getMessage().getHeader(Exchange.CONTENT_TYPE, String.class));
> assertEquals("{ \"message\":\"hello\" }",
> responseExchange.getMessage().getBody(String.class));
> }
> {code}
> This test fails with Camel 4.14.2 (or later) - the content type of
> "application/octet-stream" is returned instead of the expected
> "application/json". It passes with Camel 4.14.1, or if stream caching is
> disabled (".streamCache(false)") .
> A full reproducer is here, which can just be run with mvn clean install:
> https://github.com/driseley/cxf-responsecaching-test
