Spring Boot + Redis

启动redis

docker run --name redisServer -P -d  redis

redis自带客户端，启动客户端

docker run -it --link redisServer:db --entrypoint redis-cli redis -h db

也可以使用桌面工具Redis Desktop Manager测试

下载地址：https://redisdesktop.com/download

下载完后安装，打开程序

连接服务器

可以看到上面存进去的name

}

运行，可以在测试窗口看到结果

此时再打开桌面客户端
