資料格式

  "label_ids": " [{\"brand\":\"小破狗狗\",\"clothing\":\"shirt\"},{\"brand\":\"全心全意陪我\",\"clothing\":\"coat\"},{\"brand\":\"所迫\",\"clothing\":\"one_piece_dress\"},{\"brand\":\"圖我\",\"clothing\":\"skirt\"},{\"brand\":\"撲上去\",\"clothing\":\"bag\"},{\"brand\":\"是相濡以沫\",\"clothing\":\"decoration\"},{\"brand\":\"隨心所欲隨心所欲\",\"clothing\":\"hat\"},{\"brand\":\"其中一種\",\"clothing\":\"trousers\"},{\"brand\":\"破狗狗\",\"clothing\":\"others\"}] ",

需要解析label_ids 欄位

首先String 接收

然後是一個將資料轉戶成成bean型別集合的公共方法

public static List<? extends Object> analysisArray(String json, Type type) {
    List<Object> list = new ArrayList<>();
    try {
        JSONArray jsonArray = new JSONArray(json);
        for (int i = 0; i < jsonArray.length(); 
 
i++) {
            Object o = new Gson().fromJson(String.valueOf(jsonArray.get(i)), type);
list.add(o);
}
    } catch (JSONException e) {
        e.printStackTrace();
}
    return list;
}

呼叫的時候 只需要先建立一個bean型別的實體，因為json是陣列  所以返回的是集合  需要寫一個List<Bean> 用來接收解析之後的資料

List<GoodsLabIds> goodLabIdLists 
 
= new ArrayList<>();

goodLabIdLists.addAll((List<GoodsLabIds>) JsonUtil.analysisArray(label_ids, GoodsLabIds.class));

goodLabIdLists.addAll((List<GoodsLabIds>) JsonUtil.analysisArray(label_ids, GoodsLabIds.class));
