在Java ElasticSearch中存儲日期時間

Question

我正在嘗試存儲正在創建的實體的日期時間。 我使用org.joda.time.DateTime.now()創建一個DateTime對象。 但是它作為

{"centuryOfEra":20,"yearOfEra":2016,"yearOfCentury":16,"weekyear":2016,"monthOfYear":5,"weekOfWeekyear":18,"hourOfDay":15,"minuteOfHour":25,"secondOfMinute":28,"millisOfSecond":431,"dayOfYear":128,"year":2016,"dayOfMonth":7,"dayOfWeek":6,"era":1,"millisOfDay":55528431,"secondOfDay":55528,"minuteOfDay":925,"chronology":{"zone":{"fixed":false,"uncachedZone":{"cachable":true,"fixed":false,"id":"America/Los_Angeles"}

有沒有一種方法可以指定存儲對象的格式，如May 07 2016 14:58:44 ？ 如果將其存儲為字符串，是否還能獲得執行范圍查詢的性能優勢？

您可以將toString（）方法與格式字符串一起使用：

String dateStr = datetime.toString("dd:MM:yy");
