java Instant instant = zonedDateTime.toInstant(); 调用Instant对象的toEpochMilli()方法获取自1970年1月1日以来的毫秒数:java long milliseconds = instant.toEpochMilli(); 将以上步骤整合在一起,你可以得到以下完整的代码示例: java import java.time.LocalDateTime; import java.time.ZoneId; import java....

Java 8 LocalDateTime.now() 只提供毫秒精度 新手上路,请多包涵 是否有可能在 Java 8 中获得微秒? Java 8LocalDateTime类有一个.getNano()方法,它意味着返回nanosecondsOS (Ubuntu) 和 Linux (Ubuntu) only returnsmilliseconds(when I ran it it returned301000000which equals301 milliseconds) and I really need...
我想知道是否有办法使用新的LocalDate,LocalTime或LocalDateTime--- 或—b9b6b08c9933470d8170c 类来获取当前毫秒数8. 已知的方法如下: long currentMilliseconds =newDate().getTime(); 或者 long currentMilliseconds=System.currentTimeMillis(); 我不完全确定你所说的“当前毫秒数”是什么意思,但我假设它是自...
