I got it working. Here's what I did.
I had to implement a custom serialization to XML. Reason why is because I
my model is based on EMF <http://www.eclipse.org/modeling/emf/> and it does
its own XML. But I also had to support JSON. I did an implementation of
MessageBodyWriter for my XML serialization. I did nothing for my JSON
serialization.
The key was to register my MessageBodyWriter with jersey. I did it in in
the run method of my Application like this:
@Override
public void run(ForecastConfiguration configuration, Environment
environment)
throws Exception {
environment.jersey().register(
new IndexResource());
environment.jersey().getResourceConfig().register(new
FHIRMessageWriter<Conformance>());
}
My MessageBodyWriter looks like this:
@Produces(MediaType.APPLICATION_XML)
public class FHIRMessageWriter<T extends EObject> implements
MessageBodyWriter<T> {
Logger log = LoggerFactory.getLogger(FHIRMessageWriter.class);
protected static ResourceSet resourceSet = new ResourceSetImpl();
protected static Resource resource;
static {
FhirPackage.eINSTANCE.eClass();
XhtmlPackage.eINSTANCE.eClass();
resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().
put("xml", new XMLResourceFactoryImpl());
resource = resourceSet.createResource(URI.createURI("xxx.xml"));
}
@Override
public long getSize(T arg0, Class<?> arg1, Type arg2, Annotation[] arg3,
MediaType arg4) {
return 0;
}
@Override
public boolean isWriteable(Class<?> arg0, Type arg1, Annotation[] arg2,
MediaType arg3) {
return true;
}
@Override
public void writeTo(T ir, Class<?> clazz, Type type, Annotation[] ann,
MediaType mt,
MultivaluedMap<String, Object> mvm, java.io.OutputStream stream)
throws IOException, WebApplicationException {
log.trace("writeTo==>");
resource.getContents().add((EObject) ir);
try {
resource.save(stream, Collections.EMPTY_MAP);
} catch (IOException e) {
log.error("", e);
}
}
}
One of my REST calls in IndexResource looks like this:
@GET
@Path("/Conformance")
@Produces({MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML})
public Conformance getConformance(@HeaderParam("content-type") String
contentType) {
Conformance conformance = FhirFactory.eINSTANCE.createConformance();
conformance.setId(FHIRUtil.createId());
conformance.setUrl(ForecastUtil.URIs.FORECAST_CONFORMANCE.uri);
conformance.setStatus(FHIRUtil.CONFORMANCE_STATUS.DRAFT.code);
conformance.setExperimental(FHIRUtil.BOOLEAN.TRUE.bool);
conformance.setFhirVersion(FHIRUtil.createId());
conformance.setDate(FHIRUtil.convertDateTime(new Date()));
conformance.getProfile().add(ForecastUtil.PROFILEs.
FORECAST_IMMUNIZATIONRECOMMENDATIONRECOMMENDATION.reference);
conformance.getProfile().add(ForecastUtil.PROFILEs.
FORECAST_IMMUNIZATIONRECOMMENDATION.reference);
conformance.getProfile().add(ForecastUtil.PROFILEs.
FORECAST_IMMUNIZATION.reference);
conformance.getProfile().add(ForecastUtil.PROFILEs.FORECAST_PATIENT.
reference);
conformance.getFormat().add(FHIRUtil.FORMAT.JSON.code);
conformance.getFormat().add(FHIRUtil.FORMAT.XML.code);
return conformance;
}
Finally, I tested it all with these using RestAssured: They dump the
results so I can do a visual.
@Test
public void testConformanceJSON() {
given().
accept(ContentType.JSON).
when().
get("/forecast/Conformance").then().log().body();
}
@Test
public void testConformanceXML() {
given().
accept(ContentType.XML).
when().
get("/forecast/Conformance").then().
log().body();
}
