Java中如何实现LocalDateTime与String之间的转换呢?

LocalDateTime类型转换String类型

public static void main(String[] args) {
        DateTimeFormatter fmt = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        LocalDateTime localDateTime = LocalDateTime.now();
        String dateStr = localDateTime.format(fmt);
        System.out.println(dateStr);
    }

String类型转换LocalDateTime类型

public static void main(String[] args) {
        DateTimeFormatter fmt = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        String dateStr = "2023-11-24 11:10:40";
        LocalDateTime date2 = LocalDateTime.parse(dateStr, fmt);
        System.out.println(date2);
}
