集成redis【JWordPress前台项目实战】

写在前面

Redis是一个开源的使用ANSI C语言编写、遵守BSD协议、支持网络、可基于内存亦可持久化的日志型、Key-Value数据库,并提供多种语言的API。

它通常被称为数据结构服务器,因为值(value)可以是 字符串(String), 哈希(Map), 列表(list), 集合(sets) 和 有序集合(sorted sets)等类型。

springboot项目如何集成redis呢?带着这个问题我们继续今天的教程

代码

pom.xml添加redis依赖包

<!– 添加 spring redis 依赖 –>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-redis</artifactId>
</dependency>
