NHibernate的：如何解決這個 「方言」 的配置問題

Question

問題遇到

在運行時，我總是得到以下NHibernate.MappingException：

"Could not compile the mapping document: GI.InventoryManager.CYB.Mappings.Part.hbm.xml" 

是的，它的生成操作設置爲Embedded Resource。設置InnerException說：

"Could not find the dialect in the configuration" 

所需信息

這裏是我的配置文件命名爲hibernate.cfg.xml：

<?xml version="1.0" encoding="utf-8" ?> 
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2" > 
    <session-factory> 
    <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property> 
    <property name="connection.connection_string"> 
     Server=(local);initial catalog=GI_IM_CYB;Integrated Security=SSPI 
    </property> 
    <property name="adonet.batch_size">10</property> 
    <property name="show_sql">false</property> 
    <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property> 
    <property name="use_outer_join">true</property> 
    <property name="command_timeout">60</property> 
    <property name="query.substitutions">true 1, false 0, yes 'Y', no 'N'</property> 
    <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory,  NHibernate.ByteCode.Castle</property> 
    </session-factory> 
</hibernate-configuration> 

這實際上是一個複製粘貼從Configuration_Templates文件夾中，我只更改了以下信息：

Session Factory: "Removed the NHibernate.Test namespace and let the property for itself" 
Dialect: "From MsSql2000Dialect To MsSql2005Dialect" 
Connection_String: "I changed the Initial Catalog attribute to input my own database name" 
Factory Class: "From LinFu to Castle" 

這裏就是我如何使用它在我的代碼：

private void configBackgroundWorker_DoWork(object sender, DoWorkEventArgs e) { 
    Configuration c = new Configuration(); 
    c.AddAssembly(typeof(Part).Assembly); 
    lock (_sessionFactory) { 
     _sessionFactory = c.BuildSessionFactory(); 
    } 
}

問題

我已經試圖把方言財產上的配置線，它既不工作。

如何解決我的這個方言問題？

Answer 1

看起來還好吧，我...你見過這些相關的問題：

• nhibernate-could-not-find-oracle-dialect-in-configuration解決方案：將映射文件

• nhibernate-and-sqlite-could-not-compile-the-mapping-document解決方案之前調用configuration.Configure()：在hibernate.cfg.xml複製到輸出 目錄

這些是很容易犯的錯誤，可以引發特定的例外。

Answer 2

兩件事情會解決這個問題：

不要使用此：

Configuration c = new Configuration(); 

相反，使用這樣的：

Configuration c = new Configuration().Configure(); 

確保無論你在休眠做到這一點。 cfg.xml文件：

<mapping assembly="Your assembly"/> 

或

AddAssembly(Assembly.GetCallingAssembly()); 

這樣做會造成問題。
