关于Gson解析json时timestamp转化bean中date类型问题

 GsonBuilder builder = new GsonBuilder();

 builder.registerTypeAdapter(Date.class, new JsonDeserializer<Date>() {

       public Date deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws   JsonParseException {

                return new Date(json.getAsJsonPrimitive().getAsLong());

            }

       });

 Gson gson =builder.create();

 gson.fromJson(json,bean);
