业务超时逻辑处理

需求：下单超时、支付超时、退款超时逻辑处理，业务中对应订单状态要根据redis-key失效之后做订单状态变更的处理。
实现思路：在下单业务中设置失效key,利用redis失效key的事件监听，conf中配置 notify-keyspace-events "Ex"
/**
 * redis 失效key监听配置类
 */
@Configuration
public class RedisListenerConfig {

   @Bean
   RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory) {

      RedisMessageListenerContainer container = new RedisMessageListenerContainer();
      container.setConnectionFactory(connectionFactory);
      return container;
   }
}

/**
 * 监听redis-key过期
 */
@Component
@Log4j2
public class RedisKeyExpirationListener extends KeyExpirationEventMessageListener {

   public RedisKeyExpirationListener(RedisMessageListenerContainer listenerContainer) {
      super(listenerContainer);
   }

   /**
    *  监听 redis key失效，触发订单状态流转
    * @param message
    * @param pattern
    * @descripe  redis.conf文件 需 追加参数【 notify-keyspace-events "Ex"】
    */
   @Override
   public void onMessage(Message message, byte[] pattern) {
      PaymentsService paymentsService = SpringContextHolder.getBean(PaymentsService.class);
      OrderService orderService = SpringContextHolder.getBean(OrderService.class);
      // 获取到失效的 key，进行取消订单业务处理
      String expiredKey = message.toString();
      String[] strKey = expiredKey.split("-");
      Long orderId = Long.valueOf(strKey[2]);
      log.info("过期的订单主键 ：{}", orderId);
      RedisLock redisLock = new RedisLock(SpringContextHolder.getBean(StringRedisTemplate.class),
            NrOrderConstant.ORDER_REDIS_LOCK + orderId);
      try {

                  .getOne(Wrappers.lambdaQuery()
                        .eq(NrPayment::getOrderNo, nrOrder.getOrderNo()));

            switch (strKey[0]) {
