基於CacheManager組件的緩存產品配置

1、Couchbase

使用CacheManager組件，在配置Couchbase緩存支持時，因爲對配置節cache handle命名規則要求不瞭解，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的命名規則必須知足可經過配置名稱找到CouchbaseClientSection對應配置節，即couchbaseClients下的couchbase

Bucket名爲可選，默認爲default

格式爲<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);

2、memcached

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

    <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命名爲 enyim.com/memcached或 default,default時組件自動爲轉化爲enyim.com/memcached
