在上面的 Json 中，我有几个动态的 Json 对象键，它们会根据不同的响应而变化。我正在使用改造来解析 json。请帮助我如何为上述 JSON 创建 POJO 类。 谢谢!!

最佳答案

通常像 Gson 这样的 JSON 解析器可以解析 JSON 对象中的动态键，将对象转换为 Java Map。

在您的情况下，JSON 对象非常奇特，生成的 POJO 可能类似于:

private class Wrapper {
    String status;
    Response response;
}

private class Response {
    Map<String, Map<String, Map<String, List<Inner>>>> results;
}

private class Inner {
    String type;
    ... all other stuff
}

但是这个:Map<String, Map<String, Map<String, List<Inner>>>>我觉得不太好。

用 Gson 尝试它似乎工作正常:

Wrapper wrapper = new Gson().fromJson(json, Wrapper.class);

    Log.e(TAG, "Type: " + wrapper.response.results
        .get("C9DC8215200A9180BD4F4F15097CEB0AC6F4DB6C57FDB75F")
        .get("EDF8B7EC20005ACC5C40FF7D6E988801F5BAD83CBBCDB97F")
        .get("ED4FE2BB2008FDA9C8133FF462959C0968FAB98C4D1DB8F2").get(0).type);

日志 MainActivity: Type: student_tracker_status_type .

希望这对您有所帮助。
