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。
