gson Float.POSITIVE_INFINITY nan问题

gson无法解析 Float.NaN
NaN is not a valid double value as per JSON specification

如何解决:
1)在服务端把Map> 改为Map返回这个值
2)在客户端android
public void onResponse(Call call, Response response)
map.put("mapData",response.body());
3)对其解析
GsonBuilder gsonBuilder = new GsonBuilder();
gsonBuilder.serializeSpecialFloatingPointValues();
Gson gson = gsonBuilder.create();
Map body = (Map) mapData.get("mapData");
【gson Float.POSITIVE_INFINITY nan问题】String strPoints = mapData.get(aaa);
List points = gson.fromJson(strPoints, new TypeToken>(){}.getType());
