10hutool实战:TemporalAccessorUtil{TemporalAccessor} 工具类封装

    String dateStr = "2021-05-22T14:05:20";
    LocalDateTime localDateTime = LocalDateTime.parse(dateStr);
    Assert.assertEquals(dateStr,TemporalAccessorUtil.format(localDateTime,DateTimeFormatter.ISO_LOCAL_DATE_TIME));

    String dateStr = "2021-05-22";
    //TemporalAccessor 的实现类包含Instant LocalDateTime ZonedDateTime OffsetDateTime LocalDate LocalTime OffsetTime
    LocalDate localDate = LocalDate.parse(dateStr);
    //Date对象
    long time = TemporalAccessorUtil.toEpochMilli(localDate);
    Assert.assertEquals(DateUtil.parse(dateStr).getTime(), time);
