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

        {

                {
                    return redis.Set<T>(key, t, new TimeSpan(1, 0, 0));
                }

            catch (Exception ex)
            {
                // LogInfo 
            }
            return false;
        }
