获取未来的5分钟整点时间05,10,15,20,25...

比如预约网约车的时候，是按5分钟的整点时间

 @GetMapping("/getFiveNextTime")
    public String fiveNextTime(@RequestParam(defaultValue = "0") Integer interval) {
        Calendar calendar = Calendar.getInstance();
        calendar.add(Calendar.MINUTE, (5 - calendar.get(Calendar.MINUTE) % 5) + interval.intValue() * 5);
        calendar.set(Calendar.SECOND,0);
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        long nowTime = calendar.getTimeInMillis();
        String timeNextTime = simpleDateFormat.format(nowTime);
        // System.out.println(timeNextTime);
        return timeNextTime;
    }

测试结果 如当前时间是2024-02-04 11:14
如果入参为空时：获取的时间是2024-02-04 11:15:00

如果interval=2返回的是2024-02-04 11:25:00
就是11点15分再加2个五分钟，就是11:25
