如何在java文件中访问json数据

Question

我在字符串

中有这样的json数据

  {
   'MMTStaticCountrySearchResponse':{
      'Country':[
         {
            '-CountryCode':'IN',
            'CitiesCount':'362',
            'CountryName':'India',
            'HotelsCount':'6535'
         },
         {
            '-CountryCode':'SG',
            'CitiesCount':'1',
            'CountryName':'Singapore',
            'HotelsCount':'197'
         }
      ]
   }
}

如何访问和存储国家/地区名称？

Answer 1

杰克逊：

final ObjectMapper mapper = new ObjectMapper()
    .configure(JsonParser.Feature.ALLOW_SINGLE_QUOTES, true);

final JsonNode node = mapper.readTree(...);

for (final JsonNode element: node.get("MMTStaticCountrySearchResponse").get("Country")) {
    node.get("CountryName");
    // etc
}

Answer 2

 JSONObject obj = new JSONObject("JsonString");
      Object temp = obj.get("MMTStaticCountrySearchResponse");
        List<String> list = new ArrayList<String>(); 
        JSONObject objtemp = new JSONObject(temp.toString());
        JSONArray array = objtemp.getJSONArray("Country");
        for(int i = 0 ; i < array.length() ; i++){
            list.add(array.getJSONObject(i).getString("HotelsCount"));
            System.out.println(array.getJSONObject(i).getString("CountryName"));
            System.out.println(array.getJSONObject(i).getString("HotelsCount"));
        }
