我在家里使用 Java 和 Akka 设计新应用程序，但是我在传递 Zomato 的 api 响应时遇到了问题。

JSON 响应可以在下面找到。我用对象列表创建了 Class Restaurant 餐厅。我应该如何解析它？

{
"results_found": 131,
"results_start": 0,
"results_shown": 10,
"restaurants": [
    {
        "restaurant": {

如果 json 与您在此处粘贴的内容完全相同，则它似乎不是有效的 json。试试这个：

  {
    "results_found": 131,
    "results_start": 0,
    "results_shown": 10,
    "restaurants": [{
        "restaurant": {
            "R": {
                "res_id": 6103211
            },
            "apikey": "4972ea7a10293fc07e997364eef03d3d",

第一件事是the JSON is invalid。我假设您可以管理有效的 JSON。验证 JSON 后。

首先创建一个 Restaurant POJO 类。

餐厅类的属性：

R: obj
apikey: string
location: obj
.... like .....

添加您需要的所有字段。

之后，使用代码进行解析。array但首先，从 JSON 中取出餐馆。

gson.fromJson(restaurants, Restaurant[].class);
