RedisTemplate 使用 increasement() 和 get() 时报 SerializationException

简单来说调用incr后得到 值不会出错是没有经过redistemplate的deserialize, 而get必须经过

所以，第一次调用 get 时，因为没有值，所以是成功的。然后调用了 incr 成功。第二次再调用 get 时，反序列化失败了

 

使用 RedisAtomicInteger 来处理：org.springframework.data.redis.support.atomic.RedisAtomicInteger

------

看了下 RedisAtomicInteger 的实现，都是将 key,value 转成了 String 之后存放到 redis 中的，看来 redis 还是最适合存放 string 类型的数据。
