基于CacheManager元件的緩存産品配置

一、Couchbase

使用CacheManager元件，在配置Couchbase緩存支援時，由于對配置節cache handle命名規則要求不了解，費了點時間查了源碼才明白。

section配置節

<sectionGroup name="couchbaseClients">
      <section name="couchbase" type="Couchbase.Configuration.Client.Providers.CouchbaseClientSection, Couchbase.NetClient" />
    </sectionGroup>      

cacheManager中的cache節點配置

<managers>
      <cache name="cacheName" updateMode="Up" enableStatistics="false" enablePerformanceCounters="false">        
        <handle name="couchbaseClients/couchbase:default" ref="couchbaseHandle" expirationMode="Absolute" timeout="50s"/>
      </cache>
    </managers>      

注意：

handleName的命名規則必須滿足可通過配置名稱找到CouchbaseClientSection對應配置節，即couchbaseClients下的couchbase

Bucket名為可選，預設為default

格式為<configKey>:<bucketName>

源碼參考CacheManager.Couchbase.BucketCacheHandle

// we can configure the bucket name by having "<configKey>:<bucketName>" as handle's
            // name value
            var nameParts = configuration.Key.Split(new[] { ":" }, StringSplitOptions.RemoveEmptyEntries);
            Ensure(nameParts.Length > 0, "Handle key is not valid {0}", configuration.Key);

            this.configurationName = nameParts[0];

            if (nameParts.Length == 2)
            {
                this.bucketName = nameParts[1];
            }

            this.configuration = CouchbaseConfigurationManager.GetConfiguration(this.configurationName);
            this.bucketConfiguration = CouchbaseConfigurationManager.GetBucketConfiguration(this.configuration, this.bucketName);
            this.bucket = CouchbaseConfigurationManager.GetBucket(this.configuration, this.configurationName, this.bucketName);      

二、memcached

memcached配置時，對cacheManager中的cache節點handle的命名也和Couchbase類型，配置如下

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

<managers>
      <cache name="cacheName" updateMode="Up" enableStatistics="false" enablePerformanceCounters="false">        
        <handle name="enyim.com/memcached" ref="memcachedHandle"/>
      </cache> 
    </managers>      

或者

<managers>
      <cache name="cacheName" updateMode="Up" enableStatistics="false" enablePerformanceCounters="false">        
        <handle name="default" ref="memcachedHandle"/>
      </cache> 
    </managers>      

handle命名為enyim.com/memcached或default,default時元件自動為轉化為enyim.com/memcached
