SeckillTask.java

@Component
public class SeckillTask {

    
    @Autowired
    private RedisTemplate redisTemplate;
    
    @Autowired
    private TbSeckillGoodsMapper seckillGoodsMapper;
    
    @Scheduled(cron="0 * * * * ?")
    public void refreshSeckillGoods(){
        System.out.println("执行了秒杀商品增量更新 任务调度"+new Date());
    }

Cron表达式

注意两个特殊的域DayofMonth DayofWeek 两者必须有一个不指定数值 即 ？，因为两者会产生冲突，

SpringTask不支持第一种
