这篇文章主要介绍了java8时间转换(LocalDateTime)代码实例,文中通过示例代码介绍的非常详细,对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
1.将LocalDateTime转为自定义的时间格式的字符串
public static String getDateTimeAsString(LocalDateTime localDateTime,String format) { DateTimeFormatter formatter = DateTimeFormatter.ofPattern(format); return localDateTime.format(formatter); }
2.将long类型的timestamp转为LocalDateTime
public static LocalDateTime getDateTimeOfTimestamp(long timestamp) { Instant instant = Instant.ofEpochMilli(timestamp); ZoneId zone = ZoneId.systemDefault(); return LocalDateTime.ofInstant(instant,zone); }
3.将LocalDateTime转为long类型的timestamp
public static long getTimestampOfDateTime(LocalDateTime localDateTime) { ZoneId zone = ZoneId.systemDefault(); Instant instant = localDateTime.atZone(zone).toInstant(); return instant.toEpochMilli(); }
4.将某时间字符串转为自定义时间格式的LocalDateTime
public static LocalDateTime parseStringToDateTime(String time,String format) { DateTimeFormatter df = DateTimeFormatter.ofPattern(format); return LocalDateTime.parse(time,df); }原文链接:https://www.f2er.com/java/526574.html
