你还在使用定时任务取消订单吗

啥也不说，咱就上干货，show code

配置监听Bean

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.listener.RedisMessageListenerContainer;
import org.springframework.data.redis.serializer.GenericJackson2JsonRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;

@Configuration
public class RedisListenerConfig {
    @Autowired
    private RedisTemplate redisTemplate;

    /**
     * @return
     */
    @Bean
    public RedisTemplate redisTemplateInit() {
        redisTemplate.setKeySerializer(new StringRedisSerializer());
        redisTemplate.setValueSerializer(new GenericJackson2JsonRedisSerializer());
        return redisTemplate;
    }

    @Bean
    RedisMessageListenerContainer container(RedisConnectionFactory connectionFactory) {
        RedisMessageListenerContainer container = new RedisMessageListenerContainer();
        container.setConnectionFactory(connectionFactory);
        return container;
    }
}

监听器业务处理类

import org.springframework.data.redis.connection.Message;
import org.springframework.data.redis.listener.KeyExpirationEventMessageListener;
import org.springframework.data.redis.listener.RedisMessageListenerContainer;
import org.springframework.stereotype.Component;

@Component
public class RedisKeyExpirationListener extends KeyExpirationEventMessageListener {

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

    @Override
    public void onMessage(Message message, byte[] pattern) {
        try {
            String key = message.toString();
            //从失效key中筛选代表订单失效的key
            if (key != null && key.startsWith("order_")) {
                String orderNo = key.substring(6);
                System.out.println("订单号【" + orderNo + "】超时未支付-自动修改为已取消状态");
            }
        } catch (Exception e) {
            e.printStackTrace();
            System.out.println("【修改支付订单过期状态异常】：" + e.getMessage());
        }
    }
}

效果图

redis设置一个ttl为3的订单key value

在IDEA查看监听输出内容
