springboot中的util方法

1.获取俩个long类型的是否是同一天

public static boolean isSameDay(long time1, long time2) {
    Calendar calendar1 = Calendar.getInstance();
    calendar1.setTimeInMillis(time1);
    
    Calendar calendar2 = Calendar.getInstance();
    calendar1.setTimeInMillis(time2);

    return calendar1.get(Calendar.DAY_OF_MONTH) == calendar2.get(Calendar.DAY_OF_MONTH);
}

2.获取俩个long相差天数

  //获取俩个时间的相差天数
 public static long between_days(Date time1, Date time2) {

        Calendar cal = Calendar.getInstance();
        cal.setTime(time1);
        long time11 = cal.getTimeInMillis();
        cal.setTime(time2);
        long time22 = cal.getTimeInMillis();
        long between_days=(time22-time11)/(10003600*24);

        return between_days;
    }
