这里容易踩坑:long days=Math.abs(Period.between(target,today).getDays());System.out.println("相差:"+days+"天");} 执行结果: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 today:2022-07-07target:2021-07-07相差:0天 执行是不报错,但是结果明显是错误的。这是因为getDays()并不会将Period...

在Instant中采用两个字段表示时间戳 /** * The number of seconds from the epoch of 1970-01-01T00:00:00Z. * 该字段表示Instant时间距离原点1970-01-01T00:00:00Z的时间(单位秒) */ private final long seconds; /** * The number of nanoseconds, later along the time-line, from the seconds fi...
public static LocalDateTime dateToLocalDateMil(Long datemilli) { //将毫秒数据转化为纳秒 Instant instant = Instant.ofEpochMilli(datemilli); ZoneId zoneId = ZoneId.systemDefault(); return instant.atZone(zoneId).toLocalDateTime(); } 当然Instant 也有很多妙操作 ...

三、Instant获取long类型的10位秒数、13位毫秒数 Instant now = Instant.now().plusMillis(TimeUnit.HOURS.toMillis(8)); System.out.println(“秒数:”+now.getEpochSecond()); System.out.println(“毫秒数:”+now.toEpochMilli()); 控制台输出: ...
