测试：

@Test
        public 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return
    
            if (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";
                            }
                        }
                    }
                }
            }
        }
