没有得到任何QueryCacheHitCount。的源代码如下所示： NHibernate的3.3.1.4000，FluentnHibernate 1.3.0.733流利的nHibernate - 查询缓存不工作与“session.Query”和Cacheable（）
配置：
Factory = Fluently.Configure()
.ExposeConfiguration(c =>
c.SetProperty(NHibernate.Cfg.Environment.GenerateStatistics, "true"))
.Database(
MsSqlConfiguration.MsSql2008.ConnectionString(c => c.Is("DATA SOURCE=localhost;PERSIST SECURITY INFO=True;USER ID=AAA;Password=AAA"))
.ShowSql()
)
.Mappings(x => x.FluentMappings.AddFromAssemblyOf<Localization.NHibernate.Article>())
.ExposeConfiguration(BuildDatabase)
.Cache(
x => x.UseSecondLevelCache()
.UseQueryCache()
.ProviderClass<NHibernate.Cache.HashtableCacheProvider>())
.BuildSessionFactory();
执行：
using (var tx = session.BeginTransaction())
{
Factory.Statistics.Clear();
for (int i = 0; i < 10; i++)
{
Article s = session.Query<Article>().Cacheable().Where(x => x.Name == "O").SingleOrDefault();
}
Console.WriteLine(Factory.Statistics.QueryCacheHitCount);
Console.WriteLine(Factory.Statistics.SecondLevelCacheHitCount);
Console.WriteLine(Factory.Statistics.QueryExecutionCount);
}
只有当我改变缓存的配置，并添加我的私人QueryCacheFactory与.QueryCacheFactory<CacheFactory>()比它的作品（但我忽略了IsUpToDate检查）
public class CacheFactory : NHibernate.Cache.IQueryCacheFactory
{
public NHibernate.Cache.IQueryCache GetQueryCache(string regionName, NHibernate.Cache.UpdateTimestampsCache updateTimestampsCache, Settings settings, IDictionary<string, string> props)
{
return new MyStandardQueryCache(settings, props, updateTimestampsCache, regionName);
}
private class MyStandardQueryCache : NHibernate.Cache.StandardQueryCache
{
public MyStandardQueryCache(Settings settings, IDictionary<string, string> props, NHibernate.Cache.UpdateTimestampsCache updateTimestampsCache, string regionName)
: base(settings, props, updateTimestampsCache, regionName) { }
protected override bool IsUpToDate(Iesi.Collections.Generic.ISet<string> spaces, long timestamp)
{
return true; // SET TO TRUE than it's hitting the cache
}
}
}
