使用STRICT解析器样式时出现DateTimeParseException问题 [英] Issue with DateTimeParseException when using STRICT resolver style
问题描述
我正在尝试使用以下模式解析日期字符串: yyMMdd
和 STRICT
解析程序,如下所示:
I am trying to parse a date string using the following pattern: yyMMdd
and the STRICT
resolver as follows:
DateTimeFormatter formatter = DateTimeFormatter.ofPattern(dateFormat).withResolverStyle(ResolverStyle.STRICT);
LocalDate.parse(expiryDate, formatter);
我得到以下 DateTimeParseException
:
java.time.format.DateTimeParseException:文本'160501'无法解析
:无法从TemporalAccessor获取LocalDate:
{YearOfEra = 2016,MonthOfYear = 5,DayOfMonth = 1},ISO类型为
java.time.format.Parsed
java.time.format.DateTimeParseException: Text '160501' could not be parsed: Unable to obtain LocalDate from TemporalAccessor: {YearOfEra=2016, MonthOfYear=5, DayOfMonth=1},ISO of type java.time.format.Parsed
当我切换到默认的解析样式,即 ResolverStyle.SMART
时,它允许的日期为2月30日。
When I swith to the default resolve style, i.e. ResolverStyle.SMART
it allows such dates as 30th of February.
有人可以帮忙吗?
推荐答案
严格的解析器需要一个时代来配合YearOfEra。将您的模式更改为使用u而不是y,它将起作用,即。 uuMMdd。
The strict resolver requires an era to go with YearOfEra. Change your pattern to use "u" instead of "y" and it will work, ie. "uuMMdd".
