表格存储（TableStore）技术负责人，专注结构化数据存储领域技术和解决方案。看了下DateTypeAdaptor的代码，如下：
private synchronized Date deserializeToDate(String json) {try { return localFormat.parse(json); } catch (ParseException ignored) { } try { return enUsFormat.parse(json); } catch (ParseException ignored) { } try { return ISO8601Utils.parse(json, new ParsePosition(0)); } catch (ParseException e) { throw new JsonSyntaxException(json, e); }}
它只解析localFormat，enUsFormat或ISO8601三个标准定义的日志字符串的解析，不支持整型。
解决方案有三种：
- Json内1461689198000这个值按它的规范变为日期字符串
- Date类型改为Long类型，来解析1461689198000这个值，然后在你的类内自己转换成Date
- 自定义TypeAdaptor
