Java中日期之間的比較

Java8引入的LocalDateTime，LocalDate，LocalTime

---

public static void main(String[] args) {
        Instant now = Instant.now();

        LocalDateTime start = LocalDateTime.of(2018, 7, 24, 0, 0);
        LocalDateTime end = LocalDateTime.of(2020, 7, 24, 23, 59);

        final ZoneId myLocalZone = ZoneId.of("GMT+8");

        if (now.isAfter(start.atZone(myLocalZone).toInstant())
                && now.isBefore(end.atZone(myLocalZone).toInstant())) {
            System.out.println("hahah");

        }
    }

實體類中

/**
 * 創建時間
 */
@TableField(fill = FieldFill.INSERT)
private LocalDateTime createTime;
