package feign.jaxb;
Decodes responses using JAXB.

Basic example with with Feign.Builder:

 JAXBContextFactory jaxbFactory = new JAXBContextFactory.Builder()
      .withMarshallerJAXBEncoding("UTF-8")
      .withMarshallerSchemaLocation("http://apihost http://apihost/schema.xsd")
      .build();

 api = Feign.builder()
            .decoder(new JAXBDecoder(jaxbFactory))
            .target(MyApi.class, "http://api");
 

The JAXBContextFactory should be reused across requests as it caches the created JAXB contexts.

public class JAXBDecoder implements Decoder {
    private final JAXBContextFactory jaxbContextFactory;
    @Inject
    public JAXBDecoder(JAXBContextFactory jaxbContextFactory) {
        this. = jaxbContextFactory;
    }
    @Override
    public Object decode(Response responseType typethrows IOExceptionFeignException {
        try {
            Unmarshaller unmarshaller = .createUnmarshaller((Classtype);
            return unmarshaller.unmarshal(response.body().asInputStream());
        } catch (JAXBException e) {
            throw new DecodeException(e.toString(), e);
        } finally {
            if(response.body() != null) {
                response.body().close();
            }
        }
    }
