.Net使用Redis详解之ServiceStack.Redis
序言
本篇从.Net如何接入Reis开始，直至.Net对Redis的各种操作，为了方便学习与做为文档的查看，我做一遍注释展现，其中会对list的阻塞功能和事务的运用做二个案例，进行记录学习。
Redis官方推荐的.NET驱动类库为Service.Stack.Redis。然而网上对这个类库的中文文档不是很全面与合理，这篇文章主要就对这个类库做注释展现。不足遗漏之处还望见谅，海涵。
.Net使用Redis是非常方便与快捷与简单的，下面就让我展示下吧。
这里有必要说一下，如果你对Redis 中的基本对象数据类型还不了解，建议你看下我的前几篇Redis文章，保证要到病除。点击：我的Redis系列文章
项目中安装下载Service.Stack.Redis类库
右击项目->管理NuGet程序包->在联机中输入Reis就能出现这个类库，然后添加引入就行啦。
.Net链接Redis数据库，支持读写分离
1、配置文件
public sealed class RedisConfig : ConfigurationSection { public static RedisConfig GetConfig() { RedisConfig section = GetConfig("RedisConfig"); return section; } public static RedisConfig GetConfig(string sectionName) { RedisConfig section = (RedisConfig)ConfigurationManager.GetSection(sectionName); if (section == null) throw new ConfigurationErrorsException("Section " + sectionName + " is not found."); return section; } /// <summary> /// 可写的Redis链接地址 /// </summary> [ConfigurationProperty("WriteServerConStr", IsRequired = false)] public string WriteServerConStr { get { return (string)base["WriteServerConStr"]; } set { base["WriteServerConStr"] = value; } } /// <summary> /// 可读的Redis链接地址 /// </summary> [ConfigurationProperty("ReadServerConStr", IsRequired = false)] public string ReadServerConStr { get { return (string)base["ReadServerConStr"]; } set { base["ReadServerConStr"] = value; } } /// <summary> /// 最大写链接数 /// </summary> [ConfigurationProperty("MaxWritePoolSize", IsRequired = false, DefaultValue = 5)] public int MaxWritePoolSize { get { int _maxWritePoolSize = (int)base["MaxWritePoolSize"]; return _maxWritePoolSize > 0 ? _maxWritePoolSize : 5; } set { base["MaxWritePoolSize"] = value; } } /// <summary> /// 最大读链接数 /// </summary> [ConfigurationProperty("MaxReadPoolSize", IsRequired = false, DefaultValue = 5)] public int MaxReadPoolSize { get { int _maxReadPoolSize = (int)base["MaxReadPoolSize"]; return _maxReadPoolSize > 0 ? _maxReadPoolSize : 5; } set { base["MaxReadPoolSize"] = value; } } /// <summary> /// 自动重启 /// </summary> [ConfigurationProperty("AutoStart", IsRequired = false, DefaultValue = true)] public bool AutoStart { get { return (bool)base["AutoStart"]; } set { base["AutoStart"] = value; } } /// <summary> /// 本地缓存到期时间，单位:秒 /// </summary> [ConfigurationProperty("LocalCacheTime", IsRequired = false, DefaultValue = 36000)] public int LocalCacheTime { get { return (int)base["LocalCacheTime"]; } set { base["LocalCacheTime"] = value; } } /// <summary> /// 是否记录日志,该设置仅用于排查redis运行时出现的问题,如redis工作正常,请关闭该项 /// </summary> [ConfigurationProperty("RecordeLog", IsRequired = false, DefaultValue = false)] public bool RecordeLog { get { return (bool)base["RecordeLog"]; } set { base["RecordeLog"] = value; } } }
2、配置Redis链接
public class RedisManager { /// <summary> /// redis配置文件信息 /// </summary> private static RedisConfig RedisConfig = RedisConfig.GetConfig(); private static PooledRedisClientManager prcm; /// <summary> /// 静态构造方法，初始化链接池管理对象 /// </summary> static RedisManager() { CreateManager(); } /// <summary> /// 创建链接池管理对象 /// </summary> private static void CreateManager() { string[] WriteServerConStr = SplitString(RedisConfig.WriteServerConStr, ","); string[] ReadServerConStr = SplitString(RedisConfig.ReadServerConStr, ","); prcm = new PooledRedisClientManager(ReadServerConStr, WriteServerConStr, new RedisClientManagerConfig { MaxWritePoolSize = RedisConfig.MaxWritePoolSize, MaxReadPoolSize = RedisConfig.MaxReadPoolSize, AutoStart = RedisConfig.AutoStart, }); } private static string[] SplitString(string strSource, string split) { return strSource.Split(split.ToArray()); } /// <summary> /// 客户端缓存操作对象 /// </summary> public static IRedisClient GetClient() { if (prcm == null) CreateManager(); return prcm.GetClient(); } }
3、IRedisClient为操作Redis的接口，是.Net操作Redis的主要类库，这里我们把它接入
/// <summary> /// RedisBase类，是redis操作的基类，继承自IDisposable接口，主要用于释放内存 /// </summary> public abstract class RedisBase : IDisposable { public static IRedisClient Core { get; private set; } private bool _disposed = false; static RedisBase() { Core = RedisManager.GetClient(); } protected virtual void Dispose(bool disposing) { if (!this._disposed) { if (disposing) { Core.Dispose(); Core = null; } } this._disposed = true; } public void Dispose() { Dispose(true); GC.SuppressFinalize(this); } /// <summary> /// 保存数据DB文件到硬盘 /// </summary> public void Save() { Core.Save(); } /// <summary> /// 异步保存数据DB文件到硬盘 /// </summary> public void SaveAsync() { Core.SaveAsync(); } }
