how to convert joda datetime to String and vice versa
提问by rajsekhar
Is there a way to convert Joda DateTime to String and then from that String to DateTime.
有没有办法将 Joda DateTime 转换为 String，然后从该 String 转换为 DateTime。
DateTime d = ..;
String date = d.toString();
DateTime dateTime = DateTime.parse(date);
My question is that whether the above approach is valid or need to use formatter.
我的问题是，上述方法是否有效或需要使用格式化程序。

For those who want to parse back the value from toStringcan read my answer.
对于那些想要从中解析价值的人toString可以阅读我的答案。
If you to read the implementation of DateTimeclosely. The toStringmethod is override by AbstractInstant.
如果你DateTime仔细阅读执行。该toString方法被 覆盖AbstractInstant。
@ToString
public String toString() {
return ISODateTimeFormat.dateTime().print(this);
}
Now, parse the value from toString:
现在，解析来自的值toString：
DateTime dt = new DateTime();
String dtStr = dt.toString();
DateTimeFormatter fmt = ISODateTimeFormat.dateTime();
DateTime newDt = fmt.parse(dtStr);
