Redis 客户端配置及示例

时间:2022-01-06 22:43:26

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=""></add>
<add key="MaxReadPoolSize" value=""></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) ? : item.Attributes["value"].InnerText.ToInt32();
break;
case "MaxReadPoolSize":
config.MaxReadPoolSize = string.IsNullOrEmpty(item.Attributes["value"].InnerText) ? : item.Attributes["value"].InnerText.ToInt32();
break;
default:
config.ReadWriteHosts = new string[] { };
config.ReadOnlyHosts = new string[] { };
config.MaxWritePoolSize = ;
config.MaxReadPoolSize = ;
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>

{

}
}
catch (Exception ex)

// LogInfo
}
return false;
} /// <summary>

}
} /// <summary>

public static bool Item_Remove(string key)

}
} #endregion #region -- List -- public static void List_Add<T>(string key, T t)

}
}
public static void List_RemoveAll<T>(string key)
