Asp.net Core 快取 MemoryCache 和 Redis
https://blog.csdn.net/warrior21st/article/details/62884629
快取介面 ICacheService
快取也好,資料庫也好,我們就是進行CRUD操作,介面沒什麼好解釋的,註釋我寫的很明白,這裡就列給大家:
# 驗證快取項是否存在

快取實現類 MemoryCache
MemoryCache 這個比較簡單,有微軟比較完善的文件和一些比較好的文章,這個大家都用好久了。
我們新建一個快取實現類 MemoryCacheService 實現介面 ICacheService
public class MemoryCacheService :ICacheService { }
通過構造器注入 IMemoryCache:
protected IMemoryCache _cache;
public MemoryCacheService(IMemoryCache cache)
{
_cache = cache;
}
實現介面的方法,我們的方法都帶有 非同步 和 同步 兩種,我們節約篇章和時間,非同步的就不大家寫了,大家自己新增一下就好。
# 驗證快取項是否存在
在MemoryCache中,我們是通過 TryGetValue 來檢測 Key是否存在的
1 /// <summary> 2 /// 驗證快取項是否存在 3 /// </summary> 4 /// <param name="key">快取Key</param> 5 /// <returns></returns> 6 public bool Exists(string key) 7 { 8 if (key == null) 9 { 10 throw new ArgumentNullException(nameof(key)); 11 } 12 object cached; 13 return _cache.TryGetValue(key,out cached); 14 }
# 新增快取
三個新增方法 :
1 /// <summary> 2 /// 新增快取 3 /// </summary> 4 /// <param name="key">快取Key</param> 5 /// <param name="value">快取Value</param> 6 /// <returns></returns> 7 public bool Add(string key, object value) 8 { 9 if (key == null) 10 { 11 throw new ArgumentNullException(nameof(key)); 12 } 13 if (value == null) 14 { 15 throw new ArgumentNullException(nameof(value)); 16 } 17 _cache.Set(key, value); 18 return Exists(key); 19 } 20 /// <summary> 21 /// 新增快取 22 /// </summary> 23 /// <param name="key">快取Key</param> 24 /// <param name="value">快取Value</param> 25 /// <param name="expiresSliding">滑動過期時長(如果在過期時間內有操作,則以當前時間點延長過期時間)</param> 26 /// <param name="expiressAbsoulte">絕對過期時長</param> 27 /// <returns></returns> 28 public bool Add(string key, object value, TimeSpan expiresSliding, TimeSpan expiressAbsoulte) 29 { 30 if (key == null) 31 { 32 throw new ArgumentNullException(nameof(key)); 33 } 34 if (value == null) 35 { 36 throw new ArgumentNullException(nameof(value)); 37 } 38 _cache.Set(key, value, 39 new MemoryCacheEntryOptions() 40 .SetSlidingExpiration(expiresSliding) 41 .SetAbsoluteExpiration(expiressAbsoulte) 42 ); 43 44 return Exists(key); 45 } 46 /// <summary> 47 /// 新增快取 48 /// </summary> 49 /// <param name="key">快取Key</param> 50 /// <param name="value">快取Value</param> 51 /// <param name="expiresIn">快取時長</param> 52 /// <param name="isSliding">是否滑動過期(如果在過期時間內有操作,則以當前時間點延長過期時間)</param> 53 /// <returns></returns> 54 public bool Add(string key, object value, TimeSpan expiresIn,bool isSliding = false) 55 { 56 if (key == null) 57 { 58 throw new ArgumentNullException(nameof(key)); 59 } 60 if (value == null) 61 { 62 throw new ArgumentNullException(nameof(value)); 63 } 64 if (isSliding) 65 _cache.Set(key, value, 66 new MemoryCacheEntryOptions() 67 .SetSlidingExpiration(expiresIn) 68 ); 69 else 70 _cache.Set(key, value, 71 new MemoryCacheEntryOptions() 72 .SetAbsoluteExpiration(expiresIn) 73 ); 74 75 return Exists(key); 76 }
# 刪除快取
單個刪除 和 批量刪除
1 /// <summary> 2 /// 刪除快取 3 /// </summary> 4 /// <param name="key">快取Key</param> 5 /// <returns></returns> 6 public bool Remove(string key) 7 { 8 if (key == null) 9 { 10 throw new ArgumentNullException(nameof(key)); 11 } 12 _cache.Remove(key); 13 14 return !Exists(key); 15 } 16 /// <summary> 17 /// 批量刪除快取 18 /// </summary> 19 /// <param name="key">快取Key集合</param> 20 /// <returns></returns> 21 public void RemoveAll(IEnumerable<string> keys) 22 { 23 if (keys == null) 24 { 25 throw new ArgumentNullException(nameof(keys)); 26 } 27 28 keys.ToList().ForEach(item => _cache.Remove(item)); 29 }

# 修改快取

最後 釋放:
public void Dispose()
{
if (_cache != null)
_cache.Dispose();
GC.SuppressFinalize(this);
}
快取實現類 Redis
Redis一般都是執行的Liunx的,我們在 【(第十章)】釋出專案到 Linux 上執行 Core 專案 中介紹了,如何在Linux上開發執行Core專案,當然,我相信,很多朋友還是在 Windows 上做開發、測試的,這裡給大家一個windows 上的Redis和管理軟體,如果沒有或者不知道怎麼找的朋友可以下載下來,在windows上測試 Redis :連線可能失效 百度網盤 提取碼:uglb 百度網盤 提取碼:gl0e
安裝第一個後,啟動Redis服務就行了,管理軟體的介面也很簡潔
我們先來看我們的 RedisCacheService:
為了統一管理和切換使用,我們的 RedisCacheService 同樣實現介面 ICacheService
public class RedisCacheService : ICacheService { }
同樣,我們通過構造器注入:
protected IDatabase _cache;
private ConnectionMultiplexer _connection;
private readonly string _instance;
public RedisCacheService(RedisCacheOptions options, int database = 0)
{
_connection = ConnectionMultiplexer.Connect(options.Configuration);
_cache = _connection.GetDatabase(database);
_instance = options.InstanceName;
}
說明一下:我們需要新增一個Redis包:Microsoft.Extensions.Caching.Redis,這是官方的,但是不知道是我程式的原因還是什麼原因,總是還原失敗,命令強行還原包也不行,所以 我用的是移植的包: Microsoft.Extensions.Caching.Redis.Core,如果你們可以,最好還是用官方的包。
這裡我們寫了個方法,來組合Key值和例項名,就是Key值轉為 例項名+Key
public string GetKeyForRedis(string key)
{
return _instance + key;
}
# 驗證快取項是否存在
1 /// <summary> 2 /// 驗證快取項是否存在 3 /// </summary> 4 /// <param name="key">快取Key</param> 5 /// <returns></returns> 6 public bool Exists(string key) 7 { 8 if (key == null) 9 { 10 throw new ArgumentNullException(nameof(key)); 11 } 12 return _cache.KeyExists(GetKeyForRedis(key)); 13 }
# 新增快取
注意:我翻閱了很多資料,沒有找到Redis支援滑動和絕對過期,但是都是繼承的統一介面,所以這裡新增方法 滑動過期時沒有用的。
1 /// <summary> 2 /// 新增快取 3 /// </summary> 4 /// <param name="key">快取Key</param> 5 /// <param name="value">快取Value</param> 6 /// <returns></returns> 7 public bool Add(string key, object value) 8 { 9 if (key == null) 10 { 11 throw new ArgumentNullException(nameof(key)); 12 } 13 return _cache.StringSet(GetKeyForRedis(key), Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(value))); 14 } 15 /// <summary> 16 /// 新增快取 17 /// </summary> 18 /// <param name="key">快取Key</param> 19 /// <param name="value">快取Value</param> 20 /// <param name="expiresSliding">滑動過期時長(如果在過期時間內有操作,則以當前時間點延長過期時間,Redis中無效)</param> 21 /// <param name="expiressAbsoulte">絕對過期時長</param> 22 /// <returns></returns> 23 public bool Add(string key, object value, TimeSpan expiresSliding, TimeSpan expiressAbsoulte) 24 { 25 if (key == null) 26 { 27 throw new ArgumentNullException(nameof(key)); 28 } 29 return _cache.StringSet(GetKeyForRedis(key), Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(value)),expiressAbsoulte); 30 } 31 /// <summary> 32 /// 新增快取 33 /// </summary> 34 /// <param name="key">快取Key</param> 35 /// <param name="value">快取Value</param> 36 /// <param name="expiresIn">快取時長</param> 37 /// <param name="isSliding">是否滑動過期(如果在過期時間內有操作,則以當前時間點延長過期時間,Redis中無效)</param> 38 /// <returns></returns> 39 public bool Add(string key, object value, TimeSpan expiresIn, bool isSliding = false) 40 { 41 if (key == null) 42 { 43 throw new ArgumentNullException(nameof(key)); 44 } 45 46 47 return _cache.StringSet(GetKeyForRedis(key), Encoding.UTF8.GetBytes(JsonConvert.SerializeObject(value)), expiresIn); 48 }

同樣,釋放:
public void Dispose()
{
if (_connection != null)
_connection.Dispose();
GC.SuppressFinalize(this);
}
Startup.cs 和 快取配置
我們在 【(第八章)】讀取配置檔案(二) 讀取自定義配置檔案 中講到了如何讀取自定義配置檔案,同樣,我們把快取的配置 也放在 我們的自定義配置檔案siteconfig.json中:
我們寫一個類,來獲取配置幾個配置:
CacheProvider: _isUseRedis --- 是否使用Redis
_connectionString --- Redis連線
_instanceName ---Redis例項名稱
在 Startup.cs 的 ConfigureServices(IServiceCollection services) 中:
首先新增:services.AddMemoryCache();
判斷是否使用Redis,如果不使用 Redis就預設使用 MemoryCache:
if (_cacheProvider._isUseRedis)
{
//Use Redis
services.AddSingleton(typeof(ICacheService), new RedisCacheService(new RedisCacheOptions
{
Configuration = _cacheProvider._connectionString,
InstanceName = _cacheProvider._instanceName
},0));
}
else
{
//Use MemoryCache
services.AddSingleton<IMemoryCache>(factory =>
{
var cache = new MemoryCache(new MemoryCacheOptions());
return cache;
});
services.AddSingleton<ICacheService, MemoryCacheService>();
}
