redis的实现过程

1下载redis的安装包并按照操作安装

2开启 右击我的电脑→管理→服务→站到redis service服务 将其开启

注意：redis服务开启后其默认的ip和端口号为127.0.0.1:6379

3在项目中添加redis文件夹，在里面主要封装了三个类：

RedisConfigInfo：读取配置文件的信息

RedisManager：redis的管理

RedisOperation：redis的操作，主要是写入和读取缓存

4在webconfig中添加配置信息

在<configSections>节点里添加<section name="RedisConfig" type="CacheDemo.Redis.RedisConfigInfo, CacheDemo" />

作用：声明redis

在<configuration>中填写redis的配置信息

<RedisConfig WriteServerList="127.0.0.1:6379" ReadServerList="127.0.0.1:6379" MaxWritePoolSize="60" MaxReadPoolSize="60" AutoStart="true" LocalCacheTime="60" RecordeLog="false">
</RedisConfig>
