基于CacheManager组件的Couchbase配置

Posted 2020-06-24 行野摄色

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);
