Rest Glassfish 4中Jersey 2.5的JsonProvider未映射属性

我使用jersey作为rest客户端，但当应用程序实际部署为Glassfish 4上的war时，我遇到了问题。当我从测试运行它时，它工作正常，但在部署的应用程序映射到POJO时，所有属性都返回null

我尝试了MoxyJsonProvider，JacksonJsonProvider也定制了GsonProvider，但结果是一样的

客户端构造函数：

获取方法之一：

目前使用的Gson提供商：

已部署应用程序的输出：

[Container{id=null, command=null, image=null, created=0, status=null, ports=null, size=0, sizeRootFs=0, names=null}, Container{id=null, command=null, image=null, created=0, status=null, ports=null, size=0, sizeRootFs=0, names=null}]

有人能告诉我为什么它在玻璃鱼身上不起作用吗？或者我做错了什么

谢谢。

正如我要检查的第一件事，您是否尝试打印streamReader的内容？当我以单元测试的方式运行streamReader时，streamReader包含预期的JSON，但在glassfish中创建singleton时，它不会写入System.out流的内容，因此我认为glassfish中使用的是不同的提供程序，可能是默认的MOXy提供程序。

@Override
public List<Container> getContainers(boolean all, boolean latest, int limit, boolean showSize, String since, String before) throws DockerException {
    Response response = restClient
            .target(restURL)
            .path(CONTAINERS_LIST)
            .queryParam("all", all)
            .queryParam("limit", limit)
            .queryParam("since", since)
            .queryParam("before", before)
            .queryParam("size", showSize)
            .request(MediaType.APPLICATION_JSON)
            .get();

    switch (response.getStatus()) {
        case 200:
            LOGGER.info("Container list succesfully retrieved");
            break;
        case 400:
            LOGGER.error("Bad request parameter");
            throw new DockerException("Bad request parameter");
        case 500:
            LOGGER.error("Docker Server Error");
            throw new DockerException("Docker Server Error");
        default:
            throw new DockerException("Unknown Error");
    }

    Type type = new TypeToken<Collection<Container>>() {
    }.getType();

    List<Container> result = response.readEntity(new GenericType<List<Container>>() { });
    LOGGER.debug(String.format("Response: %s", result));
    return result;
