Json JaxB注释和Jackson空列表响应

有人有JaxB Annotation@XmlJavaTypeAdapter与Jackson合作的例子吗？尝试序列化列表对象时，我无法使其工作

我的场景如下所示。我必须使用XML注释，因为bean是自动生成的，并且不同的模块基于bean生成XML/JSON数据——这就是我所拥有的示例-

接口A，抽象类B实现了A，很多bean都是从B派生的

@XmlJavaTypeAdapter（A.class，AAdapter.class）

C类{

String type;

List<B> listOfBeans;

}

尝试序列化C的对象时，列表输出始终为空，尽管它具有所有有效的对象。看起来无法找到列表对象B的序列化程序（它调用unknownSerializer）

{ “listOfBeans”：[{}，{}]， “类型”：“holderForListOfBeans” }

我的对象映射器是-

private ObjectMapper initializeJackson() {
    ObjectMapper mapper = new ObjectMapper();
    mapper.setDateFormat(new SimpleDateFormat(TWS_DATE_FORMAT));
    mapper.configure(MapperFeature.SORT_PROPERTIES_ALPHABETICALLY, true);
    mapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
    mapper.setSerializationInclusion(Include.NON_NULL);

    // Need to use JaxB Annotation.
    JaxbAnnotationModule module = new JaxbAnnotationModule();
    mapper.registerModule(module);

    // All 64 bit fields should be quoted. Use StringSerializer for them.
    SimpleModule mySimpleModule = new SimpleModule();
    mySimpleModule.addSerializer(Long.class, new ToStringSerializer());
    mySimpleModule.addSerializer(Double.class, new ToStringSerializer());
    mapper.registerModule(mySimpleModule);

    return mapper;
}

private ObjectMapper initializeJackson() {
    ObjectMapper mapper = new ObjectMapper();
    mapper.setDateFormat(new SimpleDateFormat(TWS_DATE_FORMAT));
    mapper.configure(MapperFeature.SORT_PROPERTIES_ALPHABETICALLY, true);
    mapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
    mapper.setSerializationInclusion(Include.NON_NULL);

    // Need to use JaxB Annotation.
    JaxbAnnotationModule module = new JaxbAnnotationModule();
    mapper.registerModule(module);

    // All 64 bit fields should be quoted. Use StringSerializer for them.
    SimpleModule mySimpleModule = new SimpleModule();
    mySimpleModule.addSerializer(Long.class, new ToStringSerializer());
    mySimpleModule.addSerializer(Double.class, new ToStringSerializer());
    mapper.registerModule(mySimpleModule);

    return mapper;
}
