memcached使用说明

　　1、在服务器上注册服务

　　
　　2、启动服务：services.msc
　　

　　
　　
　　3、客户端创建服务接口
   



object Get(string key);

List<string> GetKeys();

List<object> GetValues();

void Set(string key, object value);

void Set(string key, object value, DateTime expiration);

void Set(string key, object value, TimeSpan expiration);

bool Exists(string key);

void Remove(string key);

void RemoveAll();
}
　　
　　
　　4、客户端创建接口实现
　　引入Memcached.ClientLibrary，版本为1.0.0.0，还需要引入了log4net，版本为1.2.10.0，其它版本会报异常。



public class MemcachedCache : ICache
{
private static readonly SockIOPool pool = SockIOPool.GetInstance("Project");
private static MemcachedClient client;
private static ILog log = LogManager.GetLogger("memcached-log");

static MemcachedCache()
{
var config = ConfigurationManager.AppSettings["memcached-server"];
if (string.IsNullOrWhiteSpace(config))
{
log.Info("没有配置Memcached服务器IP！");
return;
}

try
{
string[] serverList = config.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries);
pool.SetServers(serverList);
pool.Initialize();

client = new MemcachedClient();
client.PoolName = "Project";
client.EnableCompression = false;
}
catch (Exception e)
{
log.Info(string.Format("Memcached初始化异常：{0}", e.Message));
return;
}

log.Info("Memchached客户端初始化完成！");
}


public object Get(string key)
{
return client.Get(key);
}

public List<string> GetKeys()
{
var keys = new List<string>();
//IDictionaryEnumerator de = client.ke();
//while (de.MoveNext())
//{
//    keys.Add(de.Key.ToString());
//}

return keys;
}

public List<object> GetValues()
{
var values = new List<object>();
//IDictionaryEnumerator de = client.GetEnumerator();
//while (de.MoveNext())
//{
//    values.Add(de.Value);
//}

return values;
}

public void Set(string key, object value)
{
client.Set(key, value);
}

public void Set(string key, object value, DateTime expiration)
{
client.Set(key, value, expiration);
}

public void Set(string key, object value, TimeSpan expiration)
{
client.Set(key, value, DateTime.Now.Add(expiration));
}

public bool Exists(string key)
{
return client.KeyExists(key);
}

public void Remove(string key)
{
if (Exists(key))
{
client.Delete(key);
}
}

public void RemoveAll()
{
foreach (var item in GetKeys())
{
Remove(item);
}
}
}
　　
　　
　　5、客户端配置
　　

<configSections>


    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>


<appSettings>
<!--服务器IP端口列表,这里的端口号是memcached默认监控的端口号-->
<add key="memcached-server" value="192.0.0.1:11211;192.0.0.2:11211;"/>
</appSettings>

<log4net>
<root>
<level value="ALL" />
<appender-ref ref="RollingLogFileAppender" />
</root>
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="./log/aaa-" />
<param name="AppendToFile" value="true" />
<param name="MaxSizeRollBackups" value="10" />
<param name="StaticLogFileName" value="false" />
<param name="DatePattern" value="yyyyMMdd&quot;.log&quot;" />
<param name="RollingStyle" value="Date" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="[%d] [%-5t] [%-5p] -- %m%n" />
</layout>
</appender>
</log4net>
　　
　　6、客户端写入获取缓存代码
　　//Autofac获取实现



   IContainer container = ContainerInit.GetContainer();

var cache = container.Resolve<ICache>();
cache.Set("MyName", "James");
cache.Set("MyAge", 30);

var value = cache.Get("MyAge");
