1.LocalDateTime获取毫秒数 代码语言:javascript 代码运行次数:0 //获取秒数Long second=LocalDateTime.now().toEpochSecond(ZoneOffset.of("+8"));//获取毫秒数Long milliSecond=LocalDateTime.now().toInstant(ZoneOffset.of("+8")).toEpochMilli(); 2.LocalDateTime与String互转 代码语言:javascript 代码运行次...
3. LocalDateTime转String 同样，我们可以使用DateTimeFormatter类将LocalDateTime类型的日期对象格式化为字符串。String dateTimeStr = LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"));System.out.println("当前字符串日期时间：" + dateTimeStr);4. String转LocalDateTime 我们也可以使用...
