我正在尝试使用 Memcached 在我们的应用程序中实现缓存,我能够将键和值设置到服务器,但是当我尝试获取值时,它总是返回 null。下面是我的示例代码片段。

//memcached configuration in my web config
<enyim.com>
<memcached protocol="Binary">
<servers>
<add address="127.0.0.1" port="11211"/>
</servers>
<socketPool minPoolSize="10" maxPoolSize="100"
connectionTimeout="00:10:00" deadTimeout="00:05:00"/>

</memcached>
</enyim.com>
<configSections>
<sectionGroup name="enyim.com">
<section name="memcached"
type="Enyim.Caching.Configuration.MemcachedClientSection,
Enyim.Caching"/>
</sectionGroup>
</configSections>





//Get method in my controller
public object GetSalesOrder()
{
using (Enyim.Caching.MemcachedClient mc = new Enyim.Caching.MemcachedClient())
{
mc.FlushAll();
var salesOrders = salesOrderListService.GetSalesOrders();
byte[] val;
val = S.Serializer.objectToByteArray(salesOrders);
mc.Store(Enyim.Caching.Memcached.StoreMode.Set, "salesOrderList", val);
byte[] data = mc.Get<byte[]>("salesOrderList");
var returnObj = S.Serializer.ByteArrayToObject<List<Model.SalesOrderList>>((byte[])val);

return returnObj;
}
}


//Model

[Serializable]
[ResourceType("SalesOrderList")]
public class SalesOrderList
{
public int Id { get; set; }
public string Code{ get; set; }
public string CustomerName{ get; set; }
public DateTime OrderDate { get; set; }
public DateTime ShipDate { get; set; }
}

//Serializer class
public class Serializer
{
public static byte[] objectToByteArray<T>(T obj)
{
System.Runtime.Serialization.Formatters.Binary.BinaryFormatter formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();

using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
{
formatter.Serialize(ms, obj);
return ms.ToArray();
}
}

public static Object ByteArrayToObject<T>(byte[] arrBytes)
{
using (System.IO.MemoryStream ms = new System.IO.MemoryStream())
{
System.Runtime.Serialization.Formatters.Binary.BinaryFormatter formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
ms.Write(arrBytes, 0, arrBytes.Length);
ms.Seek(0, System.IO.SeekOrigin.Begin);

object obj = (Object)formatter.Deserialize(ms);

return obj;
}
}
}

我错过了什么吗?

最佳答案

我在您的代码中看到的一件事是您没有用于存储或检索数据的缓存键。我在我的代码中这样做的方式如下:

// create cachekey for storing and retrieving
var cacheKey = Guid.NewGuid().ToString();
// store for an hour
// memcachedClient.Store( StoreMode.Set, SanitizeCacheKey( cacheKey ), value, validFor )
mc.Store(StoreMode.Set, cacheKey , val, new TimeSpan(0, 1, 0, 0));

AccessCache.Get<byte[]>( cacheKey )
