KeyExpirationEventMessageListener监听redis的key过期,jedisKey过期监听

首先需要一个类继承KeyExpirationEventMessageListener，重写父类onMessage方法以及生成一个构造方法，不生成构造是要报错的,当监听到Key过期时,会自动调用该方法,还有需要装配一个RedisMessageListenerContainer对象到spring容器里面，redis配置一下
notify-keyspace-events “Ex”
下面会附上代码

// 需要装配该对象
    @Bean
    public RedisMessageListenerContainer redisMessageListenerContainer(RedisConnectionFactory factory) {
        RedisMessageListenerContainer container = new RedisMessageListenerContainer();
        container.setConnectionFactory(factory);
        return container;
    }

监听类

@Component
@Slf4j
public class RedisKeyExpireListener extends KeyExpirationEventMessageListener {


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

    @Override
    public void onMessage(Message message, byte[] pattern) {
        String key = message.toString().replace(""", "");
        log.info("监听到Key过期:{}", key);

    }
}

添加redis

设置过期时间
