Here what i has in mind:
public class MyClient {
private MyClient() {
// no-op
}
public static void main(final String[] args) throws JAXBException {
Client client = ClientBuilder.newClient();
try {
client.register(new
MyJaxbProvider<>(JAXBContext.newInstance(MyRoot.class)))
.target("http://foo.bar";)
.request()
.get();
} finally {
client.close();
}
}
@XmlRootElement
public static class MyRoot {
// ...
}
// note: base impl, error handling + stream security to enhance etc
public static class MyJaxbProvider<T> implements
MessageBodyReader<T>, MessageBodyWriter<T> {
private final JAXBContext context;
public MyJaxbProvider(final JAXBContext context) {
this.context = context;
}
private boolean isJaxb(final Class<?> type) {
return type.isAnnotationPresent(XmlRootElement.class) ||
type.isAnnotationPresent(XmlType.class);
}
@Override
public boolean isReadable(final Class<?> type, final Type genericType,
final Annotation[] annotations,
final MediaType mediaType) {
return isJaxb(type);
}
@Override
public T readFrom(final Class<T> type, final Type genericType,
Annotation[] annotations,
final MediaType mediaType, final
MultivaluedMap<String, String> httpHeaders,
final InputStream entityStream)
throws WebApplicationException {
// customize the xml size etc if no other protection in
front - see AbsrtactJAXBProvider configureReader
try {
return
context.createUnmarshaller().unmarshal(StaxUtils.createXMLStreamReader(entityStream),
type).getValue();
} catch (final JAXBException e) {
throw new WebApplicationException(Response.Status.BAD_REQUEST);
}
}
@Override
public boolean isWriteable(final Class<?> type, final Type genericType,
final Annotation[] annotations,
final MediaType mediaType) {
return isJaxb(type);
}
@Override
public void writeTo(final T t, final Class<?> type, final Type
genericType,
final Annotation[] annotations, final
MediaType mediaType,
final MultivaluedMap<String, Object>
httpHeaders, final OutputStream entityStream)
throws WebApplicationException {
try {
context.createMarshaller().marshal(t,
StaxUtils.createXMLStreamWriter(entityStream));
} catch (final JAXBException e) {
throw new WebApplicationException(Response.Status.BAD_REQUEST);
}
}
}
}
