Java获取到现在的时间差

在开发过程中经常会计算目标时间到现在的时间差，最终显示成“2天前、1周前、1年前”这种格式。

虽然代码很简单，但是每次都写还是蛮烦的，现在记录一下，同时也分享一下（大家都不用写了，哈哈）。

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";}if (day >= 365) {timeGap = day / 365 + "年前";}return timeGap;}
