我尝试LocaDate
按格式获取,所以我使用了这个接收日期并搜索要解析的格式的函数:
def getLocalDate(date: String): LocalDate = {
val pattern1 = DateTimeFormatter.ofPattern("dd MMM, yyyy")
val pattern2 = DateTimeFormatter.ofPattern("dd MMM yyyy")
val pattern3 = DateTimeFormatter.ofPattern("yyyy-MMM-dd")
val pattern4 = DateTimeFormatter.ofPattern("dd/MM/YYYY")
val pattern5 = DateTimeFormatter.ISO_LOCAL_DATE
val result = Try {
LocalDate.parse(date, pattern1)
} recover {
case _ => LocalDate.parse(date, pattern2)
} recover {
case _ => LocalDate.parse(date, pattern3)
} recover {
case _ => LocalDate.parse(date, pattern4)
} recover {
case _ => LocalDate.parse(date, pattern5)
}
result.get
}
用法:
var s1 = "01/08/2010"
getLocalDate(s1)
但出现错误:
java.time.format.DateTimeParseException: Text '01/08/2010' could not be parsed at index 0
而且我不知道为什么以及出了什么问题。
