    我把redistemplete实现由RedisTemplate 改为StringRedisTemplate就可以了，但是还是不太理解为啥会这样

    @Bean
    public RedisTemplate<String, String> redisTemplate() {

        StringRedisTemplate template = new StringRedisTemplate();
        template.setConnectionFactory(jedisConnectionFactory());
        template.setDefaultSerializer(new StringRedisSerializer());
        LOG.info("create RedisTemplate success");
        return template;
    }
