问题描述
我在解析JSON响应时遇到了一些麻烦.响应数据:
I have some trouble with parsing a JSON response. The response data:
{
"deal": {
"categorie": {
"description": "Offres Shopping",
"idcategorie": "1",
"nom": "Shopping"
},
"conditions": "2 personne au plus",
"dateAjout": "2013-01-07T00:00:00+01:00",
"dateExp": "2013-01-31T00:00:00+01:00",
"description": "nuit dans un hotel 5 etoile",
"heurexp": "12",
"iddeal": "1",
"minutesexp": "30",
"prestataire": {
"adresse": "Qu zohour 44",
"codePostale": "12600",
"description": "Hotel 5 etoiles",
"idprestataire": "1",
"nom": "Hotel ronald",
"pays": "France",
"telephone": "99999999",
"ville": "Brest"
},
"prix": "80.0",
"prixHabituel": "200.0",
"tags": "hotel",
"titre": "Nuit 5 etoiles"
}
}
当尝试解析对 List< Deal>
的响应时,出现此异常:
When trying to parse this response to a List<Deal>
I get this exception:
com.google.gson.JsonObject无法转换为com.google.gson.JsonArray
com.google.gson.JsonObject cannot be cast to com.google.gson.JsonArray
这是我用于解析的代码:
This is the code that I am using for the parse:
if (reponse != null && !reponse.isEmpty()) {
System.out.println(reponse);
Gson g = new Gson();
JsonParser parser = new JsonParser();
JsonObject jObject = parser.parse(reponse).getAsJsonObject();
JsonArray jArray = jObject.getAsJsonArray("deal"); // here goes the Exception
for (JsonElement elem : dealArray) {
deals.add(g.fromJson(elem, Deal.class));
}
System.out.println(deals.toString());
return "success";
}
谢谢
推荐答案
好,交易
不是JSON数组,而是JSON对象.因此,例外.供参考的JSON数组如下所示:
Well, deal
is not a JSON array, its a JSON object. Hence the exception. A JSON array, for reference, would look more like this:
"deal" : [{"attr" : "value"}, {"attr" : "value"}]
