Asp.net 二级缓存不在NHibernate中缓存筛选的集合?
我正在使用NHibernate 3.0配置二级缓存。二级缓存对于实体和集合非常有效,但我也有一些实体具有过滤的集合Asp.net 二级缓存不在NHibernate中缓存筛选的集合?,asp.net,hibernate,nhibernate,second-level-cache,Asp.net,Hibernate,Nhibernate,Second Level Cache,我正在使用NHibernate 3.0配置二级缓存。二级缓存对于实体和集合非常有效,但我也有一些实体具有过滤的集合 <bag name="EntityTrans" cascade="all-delete-orphan" table="EntityTrans"> <key column="entityId" not-null="true" /> <one-to-many class="MyDomain.EntityTr
<bag name="EntityTrans" cascade="all-delete-orphan" table="EntityTrans">
<key column="entityId" not-null="true" />
<one-to-many class="MyDomain.EntityTran, MyDomain" />
<filter name="cultureFilter" condition=":cultureCode = CultureCode" />
</bag>
NHibernate二级缓存不缓存上述筛选的集合。我可以在NHProf中看到,对于过滤后的集合,查询被发送到数据库。我的NHibernate配置文件包含以下条目
<class-cache class="MyDomain.EntityTran, MuDomain" region="MyRegion" usage="read-only"/>
<collection-cache collection="MyDomain.Entity.EntityTrans" region="MyRegion" usage="read-only"/>
是否需要添加更多内容来缓存已筛选的集合?目前,NHibernate不支持对已筛选集合进行二级缓存 首先我找到了这个。然后我查看了代码()并发现以下内容:
if (!(session.EnabledFilters.Count == 0) && persister.IsAffectedByEnabledFilters(session))
{
// some filters affecting the collection are enabled on the session, so do not do the put into the cache.
log.Debug("Refusing to add to cache due to enabled filters");
// todo : add the notion of enabled filters to the CacheKey to differentiate filtered collections from non-filtered;
// but CacheKey is currently used for both collections and entities; would ideally need to define two separate ones;
// currently this works in conjunction with the check on
// DefaultInitializeCollectionEventHandler.initializeCollectionFromCache() (which makes sure to not read from
// cache with enabled filters).
return; // EARLY EXIT!!!!!
