Java获取到现在的时间差

public static String formatDateGap(Date date) {
long diffSeconds = ((new Date()).getTime() - date.getTime()) / 1000;
long day = diffSeconds / (24 * 60 * 60);
long hour = (diffSeconds / (60 * 60) - day * 24);
long min = ((diffSeconds / (60)) - day * 24 * 60 - hour * 60);
long s = (diffSeconds - day * 24 * 60 * 60 - hour * 60 * 60 - min * 60);
String timeGap = s + "秒前";
if (min > 0) {
timeGap = min + "分前";
}
if (hour > 0) {
timeGap = hour + "小时前";
}
if (day > 0) {
timeGap = day + "天前";
}
if (day >= 7) {
timeGap = day / 7 + "周前";
}
if (day >= 30) {
timeGap = day / 30 + "个月前";
}
