多线程举例

直接上代码

   public int uplive(int id){
        //独立处理coupon_info表 start
        CouponCount count = new CouponCount();

        if (list0.size() > 0) {
            cc = list0.get(0);
        }
        //将活动置为上线 start
        activityDao.liveup(cc.getActivity_id());
        cardDao.updateStatus(cc.getId());
