SpringDataRedis操作Redis簡單案例

jedis 4.2 圖片 code throw .get ngs cto opera
? spring-data-redis針對jedis提供了如下功能:
-
連接池自動管理,提供了一個高度封裝的“RedisTemplate”類
-
針對jedis客戶端中大量api進行了歸類封裝,將同一類型操作封裝為operation接口
-
ValueOperations:簡單K-V操作
-
SetOperations:set類型數據操作
-
ZSetOperations:zset類型數據操作
-
HashOperations:針對map類型的數據操作
-
ListOperations:針對list類型的數據操作
簡單案例:
