Hello,
As described in the CXF document
(http://cxf.apache.org/docs/jax-rs-data-bindings.html#JAX-RSDataBindings-ConfiguringJSONprovider),
Jettison wrongly serializes List objects by default. The default approach of
Jettison is for me a bad practice.
JSONProvider has two properties 'serializeAsArray' and 'arrayKeys' to handle
this issue.
I think TomEE initializes wrongly the JSONProvider. You should by default set
serializeAsArray to 'true' and allow the developer to configure the list of
keys to put in the arrayKeys so as to produce a well-defined JSON.
private static List<Object> defaultProviders() {
final JAXBElementProvider jaxb = new JAXBElementProvider();
final Map<String, Object> jaxbProperties = new HashMap<String, Object>
();
jaxbProperties.put(Marshaller.JAXB_FRAGMENT, true);
jaxb.setMarshallerProperties(jaxbProperties);
final JSONProvider json = new JSONProvider();
// TOMEE-514
// json.setSerializeAsArray(true);
return Arrays.asList((Object) jaxb, json);
}
In order to solve my issue, I had to define my customer provider which is quite
cumbersome for a lambda developer.
@Produces("application/json")
@Consumes("application/json")
@Provider
public class CustomJSONProvider<T> extends JSONProvider<T> {
public CustomJSONProvider() {
super();
setSerializeAsArray(true);
setArrayKeys(Arrays.asList("element1", "element2"));
}
}
Regards,
Jonathan
