java LocalDateTime和Date互相轉換

//LocalDate -> Date
Date.from(localDate.atStartOfDay().atZone(ZoneId.systemDefault()).toInstant());

//LocalDateTime -> Date
Date.from(localDateTime.atZone(ZoneId.systemDefault()).toInstant());

//Date -> LocalDate
Instant.ofEpochMilli(date.getTime()).atZone(ZoneId.systemDefault()).toLocalDate();
 
//Date -> LocalDateTime
Instant.ofEpochMilli(date.getTime()).atZone(ZoneId.systemDefault()).toLocalDateTime();
