redis 存储在内存中 key-value存储主要存储热点数据(短时间大量的访客去访问)
启动命令
redis-server.exe redis.windows.conf
客户端链接redis服务器
redis-cli.exe
redis-cli.exe -h localhost -p 6379
redis-cli.exe -h localhost -p 6379 -a 123456
退出
exit

命令不区分大小写

一、字符串

二、哈希操作

三、列表操作

四、集合操作

五、有序集合

六、通用命令

七、在Java中操作Redis

7.1、Spring Data Redis
