0、先下载安装Redis服务，然后再服务列表里启动服务（Redis的默认端口是6379，貌似还有一个故事）（https://github.com/MicrosoftArchive/redis/releases）
1、nuget中安装Redis：Install-Package StackExchange.Redis -version 1.2.6
2、nuget中安装日志：Install-Package Log4Net -version 2.0.8
3、创建RedisConnectionHelp、RedisHelper类，用于调用Redis。由于是Demo我不打算用完整类，比较完整的可以查阅其他博客（例如：https://www.cnblogs.com/liqingwen/p/6672452.html）
/// <summary> /// StackExchange Redis ConnectionMultiplexer对象管理帮助类 /// </summary> public class RedisConnectionHelp { //系统自定义Key前缀 public static readonly string SysCustomKey = ConfigurationManager.AppSettings["redisKey"] ?? ""; private static readonly string RedisConnectionString = ConfigurationManager.AppSettings["seRedis"] ?? "127.0.0.1:6379"; private static readonly object Locker = new object(); private static ConnectionMultiplexer _instance; private static readonly ConcurrentDictionary<string, ConnectionMultiplexer> ConnectionCache = new ConcurrentDictionary<string, ConnectionMultiplexer>(); /// <summary> /// 单例获取 /// </summary> public static ConnectionMultiplexer Instance { get { if (_instance == null) { lock (Locker) { if (_instance == null || !_instance.IsConnected) { _instance = GetManager(); } } } return _instance; } } /// <summary> /// 缓存获取 /// </summary> /// <param></param> /// <returns></returns> public static ConnectionMultiplexer GetConnectionMultiplexer(string connectionString) { if (!ConnectionCache.ContainsKey(connectionString)) { ConnectionCache[connectionString] = GetManager(connectionString); } return ConnectionCache[connectionString]; } private static ConnectionMultiplexer GetManager(string connectionString = null) { connectionString = connectionString ?? RedisConnectionString; var connect = ConnectionMultiplexer.Connect(connectionString); return connect; } }
