LocalDateTime與String互轉

LocalDateTime轉字符串 

DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyyMMddHHmmss");
LocalDateTime time = LocalDateTime.now();
String localTime = df.format(time);

 

字符串轉LocalDateTime

String sCurTime = '20220303010101'; 
DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyyMMddHHmmss");
LocalDateTime curTimeLDT = LocalDateTime.parse(sCurTime, df);
