@Bean
    public  RedisTemplate<String, String> redis() {
        RedisTemplate<String, String> redisTemplate = new RedisTemplate<String, String>();

        redisTemplate.setConnectionFactory(jedisConnectionFactory());
        redisTemplate.setKeySerializer(new StringRedisSerializer());//key的序列化适配器
        redisTemplate.setValueSerializer(new StringRedisSerializer());//value的序列化适配器，也可以自己编写，大部分场景StringRedisSerializer足以满足需求了。

        return redisTemplate;
    }
