redis事务的实现：即将redis 的操作存放到队列，然后再执行

 public static RoomOrder takePreOrder(RoomOrder order) {//==================================start======================SessionCallback<Object> callback = new SessionCallback<Object>() {@Overridepublic Object execute(RedisOperations operations) throws DataAccessException {operations.multi();//开启事务//对redis的具体操作1//对redis的具体操作2//对redis的具体操作3return operations.exec();//执行}};redisTemplate.execute(callback);
//=================================end==========================return order;}
