从日历到ChronoLocalDateTime

我不知道你说的昨天到底是什么意思,如果你说的是昨天,那么在今天午夜之前的任何一天,你都可以用:

LocalDateTime yesterday = LocalDateTime.of(
        LocalDate.now(ZoneId.of("Europe/Madrid")),
        LocalTime.MIDNIGHT
); 
=> 2018-06-16T00:00

如果你是说昨天的午夜,你可以用 minusDays(1) 以下内容:

LocalDateTime yesterday = LocalDateTime.of(
        LocalDate.now(ZoneId.of("Europe/Madrid")),
        LocalTime.MIDNIGHT
).minusDays(1);
=> 2018-06-15T00:00

然后您可以将您的日期与此进行比较:

LocalDateTime anyDate = LocalDateTime.of(2018, Month.JUNE, 16, 9, 27, 50);
if (anyDate.isAfter(yesterday)) { }

另一个解决方案 @Ole V.V. 您可以使用:

LocalDateTime anyDate = LocalDateTime.of(2018, Month.JUNE, 16, 9, 27, 50);
LocalDate zoneDate = LocalDate.now(ZoneId.of("Europe/Madrid"));
if (anyDate.toLocalDate().isAfter(zoneDate)) { }

您可以这样转换它:

final Calendar cal = Calendar.getInstance();
cal.add(Calendar.DATE, -1);
Date ts = cal.getTime();
Instant instant = Instant.ofEpochMilli(ts.getTime());
LocalDateTime yesterday = LocalDateTime.ofInstant(instant, ZoneId.systemDefault());

if(lastClientEvent.getDateReceived().isAfter(yesterday){..}
