利用redis创建自增订单号

需求：编码+日期+订单号数量 生成订单号

/**
     * 获取当前日期
     * @return
     */
    public static String getNowDate()  {
        String res;
        SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");
        try {
            res = format.format(new Date());
        } catch (Exception e) {
            e.printStackTrace();
            throw new OrganizationServiceException("","时间装换错误");
        }
        return res;
    }


/**
     * 获取今天结束时间
     * @return
     */
    public static Date getTodayEndTime() {
        Calendar todayEnd = Calendar.getInstance();
        todayEnd.set(Calendar.HOUR_OF_DAY, 23);
        todayEnd.set(Calendar.MINUTE, 59);
        todayEnd.set(Calendar.SECOND, 59);
        todayEnd.set(Calendar.MILLISECOND, 999);
        return todayEnd.getTime();
    }

/**
     * 获取调整号 格式为 201812050001
     * @return 返回组装好的调整号
     */
    private String getAdjustNo(){
        //获取当前日期
        String code = DateUtil.getNowDate().replace("-","");
        RedisAtomicLong entityIdCounter = new RedisAtomicLong(GOLD_ADJUST_RECORD_KEY, redisTemplate.getConnectionFactory());
        //自增id
        Long increment = entityIdCounter.incrementAndGet();
        //设置过期时间为当天23:59:59:999
        entityIdCounter.expireAt(DateUtil.getTodayEndTime());

        if (increment < 10){
            return code + "000" + increment;
        } else if (increment < 100){
            return code + "00" + increment;
        }else if (increment < 1000){
            return code + "0" + increment;
        }else {
            return code + increment;
        }
    }

简单方便实现带日期的自增单号 测试过没有并发问题
