SpringBoot Redis使用
SpringBoot Redis:
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
dependencygroupIdorg.springframework.boot/groupIdartifactIdspring-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。
