如同其他的Spring template，RedisTemplate和StringRedisTemplate允许开发者通过RedisCallback接口直接与Redis对话。这赋予了开发者完整的控制，因为是直接与RedisConnection交互。注意，当使用StringRedisTemplate时，该callback接收的是一个StringRedisConnection实例。

从框架角度来说，存储在Redis中的数据都是bytes。然而，Redis本身支持不同的类型，更多时候这些是指data存储的方式，而非其表现形式。由用户来决定 信息是否需要转成String或者其他对象。SDR中，用户的类型和原生类型之间的转换，是通过RedisSerializer接口来实现的，如名所示，负责序列化过程。SDR提供了多个开箱即用的实现，其中的两个已经在上面提到了：StringRedisSerializer和JdkSerializationRedisSerializer。然而，用户也可以使用OxmSerializer来处理Object/XML映射 -- 通过Spring 3OXM支持；或者，使用JacksonJsonRedisSerializer、Jackson2JsonRedisSerializer、或者GenericJackson2JsonRedisSerializer 来实现JSON格式的存储。

注意，存储格式不仅限于值，它可以用于键、值、哈希，没有任何限制。
