ServiceStack.Redis简单封装
首先创建RedisConfig配置类
#region 单例模式
//定义单例实体
private static RedisConfig _redisConfig = null;
/// <summary>
/// 获取本逻辑类单例
/// </summary>
/// <returns></returns>
public static RedisConfig GetInstence()
{
if (_redisConfig == null)
{
_redisConfig = new RedisConfig();
}
return _redisConfig;
}
#endregion
public RedisConfig()
{
WriteServerList = ConfigurationManager.AppSettings["WriteServerList"];
ReadServerList = ConfigurationManager.AppSettings["ReadServerList"];
MaxWritePoolSize = ConvertHelper.ToInt0(ConfigurationManager.AppSettings["MaxWritePoolSize"]);
MaxReadPoolSize = ConvertHelper.ToInt0(ConfigurationManager.AppSettings["MaxReadPoolSize"]);
AutoStart = ConfigurationManager.AppSettings["AutoStart"] == "true";
LocalCacheTime = ConvertHelper.ToInt0(ConfigurationManager.AppSettings["LocalCacheTime"]);
RecordeLog = ConfigurationManager.AppSettings["RecordeLog"] == "false";
}
/// <summary>
/// 可写的Redis链接地址
/// </summary>
public string WriteServerList
{
get; set;
}

public bool RecordeLog

}
再创建一个操作工具类
public class RedisHelper
{
private int _isSafeModal = 0;
#region 单例模式
private RedisHelper() { }
public static readonly RedisHelper Instance = new RedisHelper();
private RedisHelper(int isSafeModal = 0)
{
this._isSafeModal = isSafeModal;
}
#endregion

private static string[] SplitString(string strSource, string split)
{

}
/// <summary>

public IRedisClient GetClient()

return _prcm.GetClient();
}

private PooledRedisClientManager CreateManager()
{
string[] writeServerList = SplitString(_redisConfigInfo.WriteServerList, ",");
string[] readServerList = SplitString(_redisConfigInfo.ReadServerList, ",");
return new PooledRedisClientManager(writeServerList, readServerList, new RedisClientManagerConfig
{
MaxWritePoolSize = _redisConfigInfo.MaxWritePoolSize,
MaxReadPoolSize = _redisConfigInfo.MaxReadPoolSize,
AutoStart = _redisConfigInfo.AutoStart,
//DefaultDb = _redisConfigInfo.DefaultDb,
DefaultDb = _isSafeModal == 1 ? 1 : _redisConfigInfo.DefaultDb
});
}

把缓存配置放进配置文件：
<!-- Redis缓存配置 -->
<add key="WriteServerList" value="xxxxxxxxxx" />
<add key="ReadServerList" value="xxxxxxxxxxxxxx" />
<add key="MaxWritePoolSize" value="60" />
<add key="MaxReadPoolSize" value="60" />
<add key="AutoStart" value="true" />
<add key="LocalCacheTime" value="180" />
<add key="RecordeLog" value="false" />
<!--默认缓存放置位置 -->
<add key="DefaultDb" value="0" />
配置思路： 连接池管理对象（PooledRedisClientManager） 、Redis客户端操作对象（使用接口IRedisClient）
1.创建一个创建连接池管理对象（PooledRedisClientManager）
private PooledRedisClientManager CreatePool()
{
string[] WriteList = config.Write.Split(new char[] { ','});
string[] ReadList = config.Read.Split(new char[] { ',' });
return new PooledRedisClientManager(WriteList, ReadList, new RedisClientManagerConfig
{
MaxReadPoolSize = config.MaxReadPoolSize,
MaxWritePoolSize = config.MaxWritePoolSize,
AutoStart = true,
DefaultDb= DefalutDb
});
}
2.使用PooledRedisClientManager对象创建客户端缓存操作对象
public IRedisClient GetRedis()
{
if (_prcm == null)
{
_prcm = CreatePool();
}
return _prcm.GetClient();
}
3.创建连接池管理对象 、 客户端缓存操作对象创建完成后就可以用客户端缓存操作对象封装一些方法了0.0
如：
public T Get<T>(string key)
{
using (var redisClient = GetRedis())
{
return redisClient.Get<T>(key);
}
测试下
看看Redis
List类型
看下redis
刚搞Redis，理解有限，如有不对请不吝赐教~
