springboot如何封裝redis：
redistemplate
所在包： org.springframework.data.redis.core
作用：redis模板，redis事務(wù)，序列化支持，操作redis方法
jedisconnectionfactory
所在包：org.springframework.data.redis.connection.jedis
作用：redis連接工廠類，創(chuàng)建redis連接池等
redisautoconfiguration
所在包：org.springframework.boot.autoconfigure.data.redis
作用：將redis配置文件相關(guān)信息注入工廠類
redisproperties
所在包：org.springframework.boot.autoconfigure.data.redis
作用：redis連接基礎(chǔ)類通過(guò)@configurationproperties注解將配置信息注入屬性
總結(jié)
以上所述是小編給大家介紹的redis在springboot中的使用教程，希望對(duì)大家有所幫助，如果大家有任何疑問(wèn)請(qǐng)給我留言，小編會(huì)及時(shí)回復(fù)大家的。在此也非常感謝大家對(duì)服務(wù)器之家網(wǎng)站的支持！
