Question

我正在使用sql server 2005

但是有错误消息 _sessionFactory = configuration.BuildSessionFactory（）;

有什么问题，我该如何纠正？

我的Hibernate.cfg.xml

 <property name="connection.driver_class">NHibernate.Connection.DriverConnectionProvider</property>
<property name="dialect">NHibernate.Dialect.MsSql2000Dialect</property>
<!--<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>-->
<property name="connection.connection_string">Server=localhost\SQLServer2005;database=NHibernate101;Integrated Security=True;</property>
<property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>
<mapping assembly="Infrastructure"></mapping>

和我的web.config

    <connectionStrings>
    <add name="ApplicationServices" connectionString="Server=localhost\SQLServer2005;database=NHibernate101;" providerName="NHibernate.Connection.DriverConnectionProvider"/>
</connectionStrings>

错误信息是：

NHibernate.HibernateException未被用户代码处理 Message =无法从NHibernate.Connection.DriverConnectionProvider创建驱动程序。来源= NHibernate的堆栈跟踪：在NHibernate.Connection.ConnectionProvider.ConfigureDriver（IDictionary 2 settings) at NHibernate.Connection.ConnectionProvider.Configure(IDictionary 2设置）在NHibernate.Connection.ConnectionProviderFactory.NewConnectionProvider（IDictionary 2 settings) at NHibernate.Cfg.SettingsFactory.BuildSettings(IDictionary 2个属性）在NHibernate.Cfg.Configuration.BuildSettings（）在NHibernate.Cfg.Configuration.BuildSessionFactory（）在Core：Domain.Repositories.NHibernateHelper.get_SessionFactory（）在C：\ Documents and Settings \ nHibernate101 \ NHibernate101 Final \ NHibernate101 \ Core \ Domain \ Repositories \ NHibernateHelper.cs：第22行在Core：Domain.Repositories.NHibernateHelper.OpenSession（）在C：\ Documents and Settings \ nHibernate101 \ NHibernate101 Final \ NHibernate101 \ Core \ Domain \ Repositories \ NHibernateHelper.cs：第30行在Core：Domain.Repositories.PostRepository.Core.IRepository.GetAll（）在C：\ Documents and Settings \ nHibernate101 \ NHibernate101 Final \ NHibernate101 \ Core \ Domain \ Repositories \ PostRepository.cs：第59行 at NHibernate101.Controllers.PostsController.Index（）in C：\ Documents and Settings \ nHibernate101 \ NHibernate101 Final \ NHibernate101 \ NHibernate101 \ Controllers \ PostsController.cs：第22行在lambda_method（Closure，ControllerBase，Object []）在System.Web.Mvc.ActionMethodDispatcher.Execute（ControllerBase控制器，Object []参数）在System.Web.Mvc.ReflectedActionDescriptor.Execute（ControllerContext controllerContext，IDictionary 2 parameters) at System.Web.Mvc.ControllerActionInvoker.InvokeActionMethod(ControllerContext controllerContext, ActionDescriptor actionDescriptor, IDictionary 2个参数）在System.Web.Mvc.ControllerActionInvoker。＆lt;＆gt; c__DisplayClassd.b__a（）在System.Web.Mvc.ControllerActionInvoker.InvokeActionMethodFilter（IActionFilter过滤器，ActionExecutingContext preContext，Func 1 continuation) InnerException: System.InvalidCastException Message=Unable to cast object of type 'NHibernate.Connection.DriverConnectionProvider' to type 'NHibernate.Driver.IDriver'.

Answer 1

您的配置不正确。使用这个：

<property name="hibernate.connection.provider">NHibernate.Connection.DriverConnectionProvider</property> 
<property name="hibernate.connection.driver_class">NHibernate.Driver.SqlServerCeDriver</property> 
<property name="dialect">NHibernate.Dialect.MsSql2000Dialect</property> 
<property name="connection.connection_string">Server=localhost\SQLServer2005;database=NHibernate101;Integrated Security=True;</property> 
<property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property> 
<mapping assembly="Infrastructure"></mapping>

Answer 2

您收到该错误，因为在您的Hibernate.cfg.xml中，您告诉NHibernate将NHibernate.Connection.DriverConnectionProvider类用于connection.driver_class属性。 connection.driver_class属性需要一个IDriver接口，而NHibernate.Connection.DriverConnectionProvider则没有。

你是否指定了SQL2000方言而不是2005年方言？我从来没有发生这种情况所以我不确定它是否会引发这个错误。
