2、原因

Gson无法解析位数太长的时间格式

3、解决方法

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.setDateFormat("yyyy-MM-dd HH:mm:ss").create();
        T[] list = gson.fromJson(json, type);
        return Arrays.asList(list);
