    public RedisTemplate redisTemplate(RedisConnectionFactory redisConnectionFactory) {
        //我们为了开发方方便，一般使用
        RedisTemplate template = new RedisTemplate();
        template.setConnectionFactory(redisConnectionFactory);

        // 进行序列化配置

        // 1. json序列化
        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
        ObjectMapper om = new ObjectMapper();

        // 2. String序列化

        StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();

        // key采用String的方式序列化,value采用json格式
        template.setKeySerializer(stringRedisSerializer);

        template.afterPropertiesSet();

        return template;
