NHibernate配置錯誤

我剛開始工作，作爲一名開發人員，我一遍又一遍地遇到同樣的問題。我不斷收到此錯誤：NHibernate配置錯誤

Exception (SessionFactory): An exception occurred during configuration of persistence layer./ em NHibernate.Cfg.ConfigurationSchema.HibernateConfiguration..ctor(XmlReader hbConfigurationReader, Boolean fromAppSetting) em NHibernate.Cfg.Configuration.Configure(XmlReader textReader) em NHibernate.Cfg.Configuration.Configure(String fileName, Boolean ignoreSessionFactoryConfig) em DataLayer.Repository.NHibernateHelper.get_SessionFactory() at 14/12/2016 16:52:52 0 PCService Error on: 14/12/2016 16:52:52 Referência de objeto não definida para uma instância de um objeto. em DataLayer.Repository.ConfigRobotRepository.FindByName(String name) em RSPC.PCService.ScheduleService() at line 0

我的hibernate.cfg.xml：

<?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.MySQLDialect 
    </property> 
    <property name="connection.driver_class"> 
     NHibernate.Driver.MySqlDataDriver 
    </property> 
    <property name="connection.connection_string"> 
     Server=localhost; Database=bd; Uid=ti; Pwd=************; 
    </property> 
    <property name="show_sql">false</property> 
    </session-factory> 
</hibernate-configuration>

我NHibernateHelper.cs：

public class NHibernateHelper 
    { 
     private static ISessionFactory _sessionFactory; 
     private static ISessionFactory SessionFactory 
     { 
      get 
      { 
       try 
       { 
        if (_sessionFactory == null) 
        //CreateSessionFactory(); 
        { 
         var configuration = new Configuration(); 
         //configuration.SetProperty(NHibernate.Cfg.Environment.ConnectionString, ConnectionString); 
         configuration.Configure("hibernate.cfg.xml"); 

         configuration.AddAssembly(typeof(ConfigRobot).Assembly); 

         _sessionFactory = configuration.BuildSessionFactory(); 
        } 

        return _sessionFactory; 
       } 
       catch (Exception e) 
       { 
        System.Diagnostics.StackTrace trace = new  System.Diagnostics.StackTrace(e, true); 
        var frame = trace.GetFrame(0); 
        var line = frame.GetFileLineNumber(); 
        Log("Exception (SessionFactory): " + e.Message + "/" + e.StackTrace + " at {0} " + line, Path.GetTempPath() + "PCService" + ".txt"); 
        return null; 
       } 
      } 
     } 

     public static ISession OpenSession() 
     { 
      return SessionFactory.OpenSession(); 
     }

任何幫助，非常感謝！謝謝！

這是您在調試時？確保你的NHibernate配置設置爲'Copy Always'，這樣當你生成/運行時它就會在Debug和Release文件夾中結束。 – TyCobb

你發佈了你的密碼？ :) –

@KeithNicholas剛剛編輯過，工作了這麼多小時後，我甚至沒有注意到它哈哈 –

那麼有爲什麼這可能發生多種原因：

確定configuration.Configure("hibernate.cfg.xml");線正確撿配置文件？嘗試指定完整路徑。確保將其複製到bin（發佈/調試）文件夾中。
確保配置文件中提到的細節是正確的。
嘗試使用代碼進行配置。使用NHibernate.Cfg.Configuration cfg = new NHibernate.Cfg.Configuration();。詳情請參考post。
檢查InnerException異常被拋出。繼續沿着Exceptinn樹跑下去。
確保您的實體和HBM文件正確並與數據庫結構匹配。這是最不可能的原因，因爲在這種情況下，NHibernate會拋出不同的異常，提及類的確切名稱。

代碼配置爲我解決了，謝謝！ –
