LocalDateTime转换

一、LocalDateTime转换至String互转

LocalDateTime localDateTime=LocalDateTime.parse(dates,DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));
String localDateTimeStr=LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));

二、LocalDateTime转换至Long互转

Long localDateTimeLong=Timestamp.valueOf(LocalDateTime.now()).getTime();
        LocalDateTime localDateTimeLongTime=LocalDateTime.ofInstant(Instant.ofEpochMilli(localDateTimeLong), ZoneId.systemDefault());
