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。我用org.joda.time.DateTime.now()創建DateTime對象。但它被存儲在elasticsearch作爲

{"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"} 

是有，以指定的對象的存儲像May 07 2016 14:58:44格式的方法嗎？如果我們將它存儲爲字符串，那麼我們仍然可以獲得執行範圍查詢的性能優勢？

您可以使用toString（）方法與格式字符串：

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