.Net内部缓存System.Web.Caching.Cache 和Redis缓存缓存工厂切换

有个问题,以前系统采用的是System.Web.Caching.Cache
但是redis缓存的流行
分布式的流行,缓存就被切换了.
但是在redis缓存的环境需要配置,有时候要切换回来.
这时候就弄个缓存工厂切换.
改动小小的地方就ok.

namespace Yestar.Cache.Factory
{/// <summary> /// Zhruanjian/// 创建人：TD /// 描 述：缓存工厂类/// </summary>public class CacheFactory{/// <summary>/// 定义通用的Repository/// </summary>/// <returns></returns>public static ICache Cache(){return new Cache();}}
}

定义缓存抽象类

using System;namespace Yestar.Cache
{/// <summary> /// Zhruanjian/// 创建人：TD /// 描 述：定义缓存接口/// </summary>public interface ICache{/// <summary>/// 读取缓存/// </summary>/// <param name="cacheKey">键</param>/// <returns></returns>T GetCache<T>(string cacheKey) where T : class;/// <summary>/// 写入缓存/// </summary>/// <param name="value">对象数据</param>/// <param name="cacheKey">键</param>void WriteCache<T>(T value, string cacheKey) where T : class;/// <summary>/// 写入缓存/// </summary>/// <param name="value">对象数据</param>/// <param name="cacheKey">键</param>/// <param name="expireTime">到期时间</param>void WriteCache<T>(T value, string cacheKey, DateTime expireTime) where T : class;/// <summary>/// 移除指定数据缓存/// </summary>/// <param name="cacheKey">键</param>void RemoveCache(string cacheKey);/// <summary>/// 移除全部缓存/// </summary>void RemoveCache();}
}

System.Web.Caching.Cache 缓存继承抽象类

using System;
using System.Collections;
using System.Web;namespace Yestar.Cache

}

RedisCache 缓存类

using System.Collections.Generic;
using System.Linq;
using System.Text;

看起来是不是差不多了,然后redis缓存配置,配置不是大功告成.
