LocalDateTime转换为Date

public Date fromLocalDateTime(LocalDateTime ldt){
ZoneId zoneId = ZoneId.systemDefault();
LocalDateTime localDateTime = LocalDateTime.now();
ZonedDateTime zdt = localDateTime.atZone(zoneId);

Date date = Date.from(zdt.toInstant());
return date ;

}

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