JAVA8 LocalDateTime 各个类型转换(更新中......)

long→LocalDateTime

public LocalDateTime longToLocalDateTime(Long milli) {
  DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
  ZoneId zone = ZoneId.systemDefault();
  return LocalDateTime.ofInstant(Instant.ofEpochMilli(milli),zone);
}

Date→LocalDateTime

public LocalDateTime dateToLocalDateTime(Date date) {
        Instant instant = date.toInstant();
        ZoneId zoneId = ZoneId.systemDefault();
       return instant.atZone(zoneId).toLocalDateTime();
}

LocalDateTime →Date

public Date localDateTimeTodate(LocalDateTime localDateTime) {
        ZoneId zoneId = ZoneId.systemDefault();   
        ZonedDateTime zdt = localDateTime.atZone(zoneId);
        return Date.from(zdt.toInstant());
}
