Redis 客户端配置及示例
一、redis自定义配置节点
<configSections>
<section name ="RedisConfig" type="Amy.Toolkit.RedisCache.SectionHandler"/>
</configSections>
<RedisConfig>
<add key="ReadWriteHosts" value="192.168.1.101:6379"></add>
<add key="ReadOnlyHosts" value="192.168.1.101:6379"></add>
<add key="MaxWritePoolSize" value="5"></add>
<add key="MaxReadPoolSize" value="5"></add>
</RedisConfig>
二、实现自定义配置功能
public class Config { /// <summary> /// “写”服务器地址 /// </summary> public string[] ReadWriteHosts { get; set; } /// <summary> /// “读”服务器地址 /// </summary> public string[] ReadOnlyHosts { get; set; } /// <summary> /// “写”链接池链接数 /// </summary> public int MaxWritePoolSize { get; set; } /// <summary> /// “读”链接池链接数 /// </summary> public int MaxReadPoolSize { get; set; } } public class SectionHandler : IConfigurationSectionHandler { public object Create(object parent, object configContext, XmlNode section) { Config config = new Config(); //解析配置文件信息，返回对象 if (section != null) { foreach (XmlNode item in section.ChildNodes) { switch (item.Attributes["key"].InnerText) { case "ReadWriteHosts": config.ReadWriteHosts = item.Attributes["value"].InnerText.Split(';'); break; case "ReadOnlyHosts": config.ReadOnlyHosts = item.Attributes["value"].InnerText.Split(';'); break; case "MaxWritePoolSize": config.MaxWritePoolSize = string.IsNullOrEmpty(item.Attributes["value"].InnerText) ? 1 : item.Attributes["value"].InnerText.ToInt32(); break; case "MaxReadPoolSize": config.MaxReadPoolSize = string.IsNullOrEmpty(item.Attributes["value"].InnerText) ? 1 : item.Attributes["value"].InnerText.ToInt32(); break; default: config.ReadWriteHosts = new string[] { }; config.ReadOnlyHosts = new string[] { }; config.MaxWritePoolSize = 1; config.MaxReadPoolSize = 1; break; } } } return config; } }
三、实现redis客户端功能
public class RedisFactory { private static Config config = (Config)System.Configuration.ConfigurationManager.GetSection("RedisConfig"); #region -- 连接信息 -- public static PooledRedisClientManager prcm = new PooledRedisClientManager(config.ReadWriteHosts, config.ReadOnlyHosts, new RedisClientManagerConfig { MaxWritePoolSize = config.MaxWritePoolSize, // “写”链接池链接数 MaxReadPoolSize = config.MaxReadPoolSize, // “读”链接池链接数 AutoStart = true, }); #endregion #region -- Item -- /// <summary> /// 设置单体 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="key"></param> /// <param name="t"></param> /// <param name="timeSpan"></param> /// <returns></returns> public static bool Item_Set<T>(string key, T t) { try { using (IRedisClient redis = prcm.GetClient()) { return redis.Set<T>(key, t, new TimeSpan(1, 0, 0)); } } catch (Exception ex) { // LogInfo } return false; } /// <summary> /// 获取单体 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="key"></param> /// <returns></returns> public static T Item_Get<T>(string key) where T : class { using (IRedisClient redis = prcm.GetReadOnlyClient()) { return redis.Get<T>(key);

return redisTypedClient.RemoveItemFromList(redisTypedClient.Lists[key], t) > 0; } } public static void List_RemoveAll<T>(string key) { using (IRedisClient redis = prcm.GetClient()) { var redisTypedClient = redis.GetTypedClient<T>(); redisTypedClient.Lists[key].RemoveAll(); } } public static long List_Count(string key) { using (IRedisClient redis = prcm.GetReadOnlyClient()) { return redis.GetListCount(key); } } public static List<T> List_GetRange<T>(string key, int start, int count) { using (IRedisClient redis = prcm.GetReadOnlyClient()) { var c = redis.GetTypedClient<T>(); return c.Lists[key].GetRange(start, start + count - 1); } } public static List<T> List_GetList<T>(string key) { using (IRedisClient redis = prcm.GetReadOnlyClient()) { var c = redis.GetTypedClient<T>();

} } public static bool Set_Contains<T>(string key, T t) { using (IRedisClient redis = prcm.GetClient()) { var redisTypedClient = redis.GetTypedClient<T>(); return redisTypedClient.Sets[key].Contains(t); } } public static bool Set_Remove<T>(string key, T t) { using (IRedisClient redis = prcm.GetClient()) { var redisTypedClient = redis.GetTypedClient<T>(); return redisTypedClient.Sets[key].Remove(t); } } #endregion #region -- Hash -- /// <summary> /// 判断某个数据是否已经被缓存 /// </summary> /// <typeparam name="T"></typeparam> /// <param name="key"></param> /// <param name="dataKey"></param> /// <returns></returns> public static bool Hash_Exist<T>(string key, string dataKey) { using (IRedisClient redis = prcm.GetReadOnlyClient()) { return redis.HashContainsEntry(key, dataKey);
