nhibernate配置拋出異常

Question

配置（持久層）nhibernate期間，我收到一個異常。消息說，nhibernate找不到配置文件hibernate.cfg.xml。但我欺騙了我的文件，並將其設置爲始終複製到輸出。我在單獨的程序集中存儲映射和持久類。但是控制檯項目和類庫項目都在其outpt文件夾中有配置文件。

配置文件

<?xml version="1.0" encoding="utf-8" ?> 
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> 
    <session-factory> 
    <property name="connection.provider"> 
     NHibernate.Connection.DriverConnectionProvider 
    </property> 
    <property name="dialect"> 
     NHibernate.Dialect.MsSql2008Dialect 
    </property> 
    <property name="connection.driver_class"> 
     NHibernate.Driver.SqlClientDriver 
    </property> 
    <property name="connection.connection_string"> 
     Data Source=(local); Initial Catalog=KrossThoughtDB; 
     Integrated Security=SSPI 
    </property> 
    <property name="show_sql"> 
     true 
    </property> 
    <mapping resource="MyApp.Domain.Model.Entities.Mappings.User.hbm.xml" assembly="MyApp.Domain" /> 
    <mapping resource="MyApp.Domain.Model.Entities.Mappings.Blog.hbm.xml" assembly="MyApp.Domain" /> 
    <mapping resource="MyApp.Domain.Model.Entities.Mappings.Post.hbm.xml" assembly="MyApp.Domain" /> 
    <mapping resource="MyApp.Domain.Model.Entities.Mappings.Category.hbm.xml" assembly="MyApp.Domain" /> 
    <mapping resource="MyApp.Domain.Model.Entities.Mappings.Feedback.hbm.xml" assembly="MyApp.Domain" /> 
    </session-factory> 
</hibernate-configuration> 

而且我使用了NHibernate的官方文檔中提供NHibernate會話助手實現。

會議助手

public sealed class SessionHelper 
{ 
    private const String CurrentSessionKey = "nhibernate.current_session"; 
    private static readonly ISessionFactory sessionFactory; 

    static SessionHelper() 
    { 
     sessionFactory = new Configuration(). 
      Configure(). 
      BuildSessionFactory(); 
    } 

    public static ISession GetCurrentSession() 
    { 
     var context = HttpContext.Current; 
     var currentSession = context.Items[CurrentSessionKey] as ISession; 

     if(null == currentSession) 
     { 
      currentSession = sessionFactory.OpenSession(); 
      context.Items[CurrentSessionKey] = currentSession; 
     } 

     return currentSession; 
    } 

    public static void CloseSession() 
    { 
     var context = HttpContext.Current; 
     var currentSession = context.Items[CurrentSessionKey] as ISession; 

     if(null == currentSession) 
     {    
      return; 
     } 

     currentSession.Close(); 
     context.Items.Remove(CurrentSessionKey); 
    } 

    public static void CloseSessionFactory() 
    { 
     if(null != sessionFactory) 
     { 
      sessionFactory.Close(); 
     } 
    } 
} 

然後我把這個代碼我的示例控制檯應用程序內

客戶端代碼

private static void Main(String[] args) 
{ 
    // the next line exception's thrown 
    using(var session = SessionHelper.GetCurrentSession()) 
    using(var tx = session.BeginTransaction()) 
    { 
     // some actions... 
     tx.Commit(); 
    } 
} 

幫助！

Answer 1

確保以下* config文件結構存在：

<configuration> 
    <configSections> 
     <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"/> 
    </configSections> 
    <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2"> 
    .... 
    </hibernate-configuration> 
</configuration> 

Answer 2

嘗試將hibernate.cfg.xml的「複製到輸出目錄」屬性設置爲「始終複製」。
