XmlMapper seems to ignore custom serializer about jackson-dataformat-xml HOT 7 CLOSED

final ObjectMapper mapper = new XmlMapper();
final SimpleModule = new JacksonXmlModule();
module.addSerializer(Item.class, new ItemSerializer());
mapper.registerModule( module );

@Provider
@Produces({ MediaType.TEXT_XML, MediaType.APPLICATION_XML })
public class XmlMapperContextResolver implements ContextResolver<XmlMapper> {
	
	private Map<String, XmlMapper> xmlMapperMap = new HashMap<>(2); 
	
	@Override
	public XmlMapper getContext(Class<?> type) {
		
			return xmlMapperMap.get("model");
		
	}

	public XmlMapperContextResolver() {
		
		XMLInputFactory xMLInputFactory = XMLInputFactory.newInstance();
		xMLInputFactory.setProperty(XMLInputFactory.SUPPORT_DTD, false); // This disables DTDs entirely for that factory
		xMLInputFactory.setProperty("javax.xml.stream.isSupportingExternalEntities", false); // disable external entities
		
		
		final XmlMapper modelXmlMapper = new XmlMapper(xMLInputFactory);
		final XmlMapper defaultXmlMapper = new XmlMapper(xMLInputFactory);
		
		xmlMapperMap.put("model", modelXmlMapper);
		
		JacksonXmlModule module = new JacksonXmlModule();
		module.setDefaultUseWrapper(false);
		
		module.addSerializer(PropertyMap.class, new PropertyMapSerializer());
		module.addSerializer(OptionList.class, new OptionListSerializer());
		module.addSerializer(MessageBeanList.class, new MessageBeanSerializer());
		module.addSerializer(PropertyPoolMap.class, new PropertyPoolMapSerializer());
		
		module.addSerializer(ModelAndModelGroupList.class, new ModelGroupSerializer());
		
   
		modelXmlMapper.configure(SerializationFeature.INDENT_OUTPUT, true);
		modelXmlMapper.configure(SerializationFeature.WRAP_ROOT_VALUE, true);
		modelXmlMapper.registerModule(module);
