默认情况下,jackson/fastjson将java Date/Timestamp类型序列化为时间戳,也就是1970年1月1日0点以来的毫秒数。如果要显示为用户友好表示: Jackson 可以: SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); objectMapper.setDateFormat(sdf) ...
timestampValue继承了java.util.Date,所以可以借此来讲oracle中的timestamp字段在jdbc的获取方式下,转换为util下的Date类并格式化,then done! /** * 转换映射表映射值 * * @param obj * 转换对象 * @param dataType * 转换类型 1-字符串;2-小数;3-整型;4-日期时间 ...
