Redis数据访问

RedisTemplate

Redis主要操作接口

接口	作用
基本类型操作	-
ValueOperations	Redis string操作
ListOperations	Redis list 操作
SetOperations	Redis set 操作
ZSetOperations	Redis zset 操作
HashOperations	Redis hash 操作
HyperLogLogOperations	Redis HyperLogLog operations like (pfadd, pfcount,…​)
GeoOperations	Redis geospatial operations like GEOADD, GEORADIUS,…​)
批量操作	-
BoundValueOperations	Redis string (or value) key批量操
BoundListOperations	Redis list key 批量操
BoundSetOperations	Redis set key 批量操
BoundZSetOperations	Redis zset (or sorted set) key 批量操
BoundHashOperations	Redis hash key 批量操
BoundGeoOperations	Redis key bound geospatial operations.

StringRedisTemplate

org.springframework.data.redis.core.StringRedisTemplate类提供了基于String类型操作类，可用于简化Key、Value都是String类型时的操作。
