SpringBoot Redis的使用

官方文档：

官方文档：Spring Data Redis :: Spring Data Redis

和jedis一样，SpringBoot Redis 也可以让我在Java代码中使用redis，同样也是通过引入maven依赖的形式。

创建springboot项目：

创建项目时勾选此依赖：

 想在已有的springboot项目使用也可以直接添加依赖：

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

 yml文件:

spring:redis:host: 127.0.0.1port: 8888
server:port:8081

我们写的Java代码，会发送请求到127.0.0.1:8888然后被映射到云服务的端口，server.port:8080是我们springboot项目的访问端口，注意区分这两个端口的意义。
