基于Senparc.CO2NET 缓存策略扩展的缓存使用方法

没啥说的,直接上代码

1、缓存  CacheFactory 实现:

//-----------------------------------------------------------------------
// <copyright file="CacheFactory.cs" company="FenSiShengHuo, Ltd.">
// Copyright (c) 2018 , All rights reserved.
// </copyright>
//----------------------------------------------------------------------- using Senparc.CO2NET.Cache;
using Senparc.Weixin.Cache;
using System; namespace DotNet.WeChat.CommonService.Utilities
{
using DotNet.MVC.Infrastructure.Models;

/// </summary>
public class CacheFactory
{
/// <summary>
/// 缓存处理
/// </summary>
/// <param name="cacheKey">缓存的Key</param>
/// <param name="proc">处理函数</param>
/// <param name="isCache">是否从缓存取</param>
/// <param name="refreshCache">是否强制刷新缓存</param>
/// <param name="expireAt">什么时候过期</param>
/// <returns></returns>
public static HashSetCacheModel<T> Cache<T>(string cacheKey, Func<HashSetCacheModel<T>> proc,bool isCache = false, bool refreshCache = false)
{
HashSetCacheModel<T> result;
if (!isCache)
{
result = proc();
}
else
{
IContainerCacheStrategy containerCache = LocalContainerCacheStrategy.Instance;
IBaseObjectCacheStrategy baseCache = containerCache.BaseCacheStrategy();
// 缓存
if (baseCache.CheckExisted(cacheKey)) //判断是否有缓存
{
//已经缓存
if (refreshCache)//是否强制刷新缓存
{
//强制刷新
result = proc();
baseCache.Update(cacheKey, result);
}
else
{
//不强制刷新
result = baseCache.Get<HashSetCacheModel<T>>(cacheKey);
// 判断是否过期了
if (result.ExpireAt < DateTime.Now)
{
result = proc();
baseCache.Update(cacheKey, result);
}
}
}
else
{
// 缓存中没有数据 获取一次存入缓存
result = proc();
baseCache.Set(cacheKey, result);
}
}
return result;
}
}
}
注意:Senparc 底层的Redis使用了HashSet数据结构

2、使用方法:注释里是以前的写法,使用CacheFactory后简化了操作
        /// <summary>
/// 获取微信用户
/// </summary>
/// <param name="weixinAppId"></param>
/// <param name="openId"></param>
/// <param name="refresh"></param>
/// <returns></returns>
protected WechatUserEntity GetWechatUser(string weixinAppId, string openId, bool refresh = false)
{
WechatUserEntity wechatUserEntity = null;
// 进行缓存
try
{
string cacheKey = "WechatUser:" + weixinAppId + ":" + openId;
HashSetCacheModel<WechatUserEntity> hashCacheModel= CacheFactory.Cache<WechatUserEntity>(cacheKey, () =>
{
WechatUserManager wechatUserManager = new WechatUserManager();
wechatUserEntity = wechatUserManager.GetObjectByWechatAppIdByOpenId(weixinAppId, openId);
var cacheModel = new HashSetCacheModel<WechatUserEntity>();
cacheModel.CreateOn = DateTime.Now;
cacheModel.ExpireAt = DateTime.Now.AddMinutes();
cacheModel.Value = wechatUserEntity;
return cacheModel;
});
return hashCacheModel.Value; //IContainerCacheStrategy containerCache = LocalContainerCacheStrategy.Instance;
//IBaseObjectCacheStrategy baseCache = containerCache.BaseCacheStrategy();
//HashSetCacheModel<WechatUserEntity> cacheModel = null;
//// 强制刷新缓存
//if (refresh)
//{
// if (baseCache.CheckExisted(key))
// {
// baseCache.RemoveFromCache(key);
// }
//}
//if (baseCache.CheckExisted(key))
//{
// cacheModel = baseCache.Get<HashSetCacheModel<WechatUserEntity>>(key);
// if (cacheModel.ExpireAt < DateTime.Now)
// {
// // 过期了,要更新一次
// WechatUserManager wechatUserManager = new WechatUserManager();
// wechatUserEntity = wechatUserManager.GetObjectByWechatAppIdByOpenId(weixinAppId, openId);
// cacheModel = new HashSetCacheModel<WechatUserEntity>();
// cacheModel.CreateOn = DateTime.Now;
// cacheModel.ExpireAt = DateTime.Now.AddMinutes(10);
// cacheModel.Value = wechatUserEntity;
// baseCache.Update(key, cacheModel);
// }
// wechatUserEntity = cacheModel.Value;
//}
//else
//{
// WechatUserManager wechatUserManager = new WechatUserManager();
// wechatUserEntity = wechatUserManager.GetObjectByWechatAppIdByOpenId(weixinAppId, openId);
// cacheModel = new HashSetCacheModel<WechatUserEntity>();
// cacheModel.CreateOn = DateTime.Now;
// cacheModel.ExpireAt = DateTime.Now.AddMinutes(10);
// cacheModel.Value = wechatUserEntity;
// baseCache.Set(key, cacheModel);
//}
}
catch (Exception ex)
{
NLogHelper.Warn(ex, "GetCurrentAutoreplyInfo,weixinAppId=" + weixinAppId);
} return wechatUserEntity;
}

3、HashSetCacheModel 实体,对Hset值的一次封装

}
