基于CacheManager组件的缓存产品配置

一、Couchbase

使用CacheManager组件，在配置Couchbase缓存支持时，由于对配置节cache handle命名规则要求不了解，费了点时间查了源码才明白。

section配置节

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

cacheManager中的cache节点配置

<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的命名规则必须满足可通过配置名称找到CouchbaseClientSection对应配置节，即couchbaseClients下的couchbase

Bucket名为可选，默认为default

格式为<configKey>:<bucketName>

源码参考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配置时，对cacheManager中的cache节点handle的命名也和Couchbase类型，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命名为enyim.com/memcached或default,default时组件自动为转化为enyim.com/memcached
