springboot如何封装redis：
redistemplate
所在包： org.springframework.data.redis.core
作用：redis模板，redis事务，序列化支持，操作redis方法
jedisconnectionfactory
所在包：org.springframework.data.redis.connection.jedis
作用：redis连接工厂类，创建redis连接池等
redisautoconfiguration
所在包：org.springframework.boot.autoconfigure.data.redis
作用：将redis配置文件相关信息注入工厂类
redisproperties
所在包：org.springframework.boot.autoconfigure.data.redis
作用：redis连接基础类通过@configurationproperties注解将配置信息注入属性
总结
