        FastJson2JsonRedisSerializer serializer = new FastJson2JsonRedisSerializer(Object.class);

        // 使用StringRedisSerializer来序列化和反序列化redis的key值
        template.setKeySerializer(new StringRedisSerializer());
        template.setValueSerializer(serializer);

        // Hash的key也采用StringRedisSerializer的序列化方式
        template.setHashKeySerializer(new StringRedisSerializer());

        template.afterPropertiesSet();
        return template;

    }


    @Override
    public void onMessage(Message message, byte[] pattern) {
        logger.info("过期key:" + message.toString());
        String key = message.toString();
        // 业务处理
