java 实现 发布了多久的时间描述：几分钟前，几小时前，几天前，几个月前，几年前

本文主要是介绍java 实现 发布了多久的时间描述：几分钟前，几小时前，几天前，几个月前，几年前，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

测试：

    @Testpublic void time() {String time = "2017-10-26 15:33:00";Date date = strToDateLong(time);System.out.println(timeUtile(date));}

工具：

 

     public static Date strToDateLong(String strDate) {SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");ParsePosition pos = new ParsePosition(0);Date strtodate = formatter.parse(strDate, pos);return strtodate;}String timeUtile(Date inTime) {// 拿到当前时间戳和发布时的时间戳，然后得出时间戳差Date curTime = new Date();long timeDiff = curTime.getTime() - inTime.getTime();//上面一行代码可以换成以下（兼容性的解决）// 单位换算long min = 60 * 1000;long hour = min * 60;long day = hour * 24;long week = day * 7;long month = week * 4;long year = month * 12;DecimalFormat df = new DecimalFormat("#");// 计算发布时间距离当前时间的周、天、时、分double exceedyear = Math.floor(timeDiff / year);double exceedmonth = Math.floor(timeDiff / month);double exceedWeek = Math.floor(timeDiff / week);double exceedDay = Math.floor(timeDiff / day);double exceedHour = Math.floor(timeDiff / hour);double exceedMin = Math.floor(timeDiff / min);// 最后判断时间差到底是属于哪个区间，然后returnif (exceedyear < 100 && exceedyear > 0) {return df.format(exceedyear) + "年前";} else {if (exceedmonth < 12 && exceedmonth > 0) {return df.format(exceedmonth) + "月前";} else {if (exceedWeek < 4 && exceedWeek > 0) {return df.format(exceedWeek) + "星期前";} else {if (exceedDay < 7 && exceedDay > 0) {return df.format(exceedDay) + "天前";} else {if (exceedHour < 24 && exceedHour > 0) {return df.format(exceedHour) + "小时前";} else {return df.format(exceedMin) + "分钟前";}}}}}}
