Nhibernate Search 更新后侦听器

Question

我已经将 nHibernate 搜索与我的 nhibernate/ActiveRecord 项目集成在一起。

我试图让我的更新后侦听器正常工作，但似乎每次我更新用 [Indexed] 属性装饰的对象之一时，它都会导致 nhibernate.search 创建一个新的 IndexReader (Workspace.cs GetIndexReader方法）大约需要30秒！

知道为什么 nhibernate.search 这样做吗？

这是我的配置

<configSections>
    <section name="activerecord" type="Castle.ActiveRecord.Framework.Config.ActiveRecordSectionHandler, Castle.ActiveRecord" />
    <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"/>
    </configSections>
  <activerecord isWeb="true">
    <config>
      <add key="connection.driver_class" value="NHibernate.Driver.SqlClientDriver" />
      <add key="dialect" value="NHibernate.Dialect.MsSql2000Dialect" />
      <add key="connection.provider" value="NHibernate.Connection.DriverConnectionProvider" />
      <add key="connection.connection_string" value="Data Source=***;user id=****;password=****;Initial Catalog=*****" />
      <add key="hibernate.search.default.directory_provider" value="NHibernate.Search.Store.FSDirectoryProvider, NHibernate.Search" /> 
      <add key="hibernate.search.default.indexBase" value="C:\LuceneIndex" />
      <add key="hibernate.search.analyzer" value="Lucene.Net.Analysis.Standard.StandardAnalyzer, Lucene.Net"/>
      <add key="hibernate.search.indexing_strategy" value="event" />
      <add key="hibernate.search.reader.strategy" value="shared" />  
    </config>
  </activerecord>
  <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
    <session-factory>
      <property name="proxyfactory.factory_class"> NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu </property>
      <event type="delete">
        <listener class="SoftDeleteListener, Mydll"/>
      </event>
      <event type="post-update">
        <listener class="NHibernate.Search.Event.FullTextIndexEventListener, NHibernate.Search" />
      </event>
      <event type="post-insert"> 
        <listener class="NHibernate.Search.Event.FullTextIndexEventListener, NHibernate.Search" />
      </event>
      <event type="post-delete">
        <listener class="NHibernate.Search.Event.FullTextIndexEventListener, NHibernate.Search" />
      </event>
    </session-factory>
  </hibernate-configuration>

，我正在以编程方式添加我的事件侦听器（目前仅更新后）

NHibernate.Cfg.Configuration configuration = ActiveRecordMediator.GetSessionFactoryHolder().GetConfiguration(typeof(ActiveRecordBase));
configuration.SetListeners(ListenerType.PostUpdate, new IPostUpdateEventListener[] { new FullTextIndexEventListener() });

Answer 1

事实证明，我的应用程序抛出了异常，但除非我正在调试，否则不会被捕获。

Answer 2

如果通过配置添加侦听器，则无需以编程方式添加侦听器。

您是否尝试过从配置中删除以下行：

<add key="hibernate.search.indexing_strategy" value="event" />
<add key="hibernate.search.reader.strategy" value="shared" />
