Nhibernate 在SharpArchitecture中使用Npgsql时出现的问题

在SharpArchitecture中使用Npgsql时，是否有人可以帮助我。我很沮丧。我使用了Postgresql 8.4、Npgsql 2.0.11、SharpArchitecture 2.0.0.0和visual studio 2010

我的示例项目名为“success”

1） 我在每个项目中都引用了Npgsql驱动程序，并按如下方式配置了我的NHibernate.config，我觉得没有问题：

<property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
  <property name="connection.driver_class">NHibernate.Driver.NpgsqlDriver</property>
  <property name="dialect">NHibernate.Dialect.PostgreSQLDialect</property>
  <property name="connection.connection_string">
    Server=localhost;Database=***;Encoding=UNICODE;User ID=***;Password=***;
  </property>

6） 我创建了视图，到目前为止还可以，但在最后一步，项目显示错误如下。但是，将项目更改为SQLServer2005平台时没有问题。 错误出现在Global.asax.cs：

...
private void InitialiseNHibernateSessions()
{
NHibernateSession.ConfigurationCache = new NHibernateConfigurationFileCache();
//the follow line codes make error when using Npgsql, but no error when using SQL Server 2005 
NHibernateSession.Init(
this.webSessionStorage,
new[] { Server.MapPath("~/bin/success.Infrastructure.dll") },
new AutoPersistenceModelGenerator().Generate(),
Server.MapPath("~/NHibernate.config"));
}
...

错误详细信息如下所示：

...
public AutoPersistenceModel Generate()
    {
        var mappings = AutoMap.AssemblyOf<studentMap>(new AutomappingConfiguration())
            .UseOverridesFromAssemblyOf<studentMap>()    //alter AutoMapping Assembly
            .OverrideAll(map => { map.IgnoreProperty("Id"); })  // ignore id property, and the program recognize the "sno" as the PK, test OK
...

 ...
 public ActionResult Index()
    {
        var students = this.studentRepository.GetAll();
        return View(students);
    }

    private readonly StudentRepository studentRepository;

    public StudentsController(StudentRepository studentRepository)
    {
        this.studentRepository = studentRepository;
    }

    [Transaction]
    [HttpGet]
    public ActionResult CreateOrUpdate(string sno)
    {
        student s = studentRepository.GetStudentFromSno(sno);
        return View(s);
    }

    [Transaction]
    [ValidateAntiForgeryToken]
    [HttpPost]
    public ActionResult CreateOrUpdate(student s)
    {
        if (ModelState.IsValid && s.IsValid())
        {
            studentRepository.SaveOrUpdate(s);
            return this.RedirectToAction("Index");
        }
        return View(s);
    }

    [Transaction]
    [ValidateAntiForgeryToken]
    [HttpPost]
    public ActionResult Delete(string sno)
    {
        var s = studentRepository.GetStudentFromSno(sno);
        if (s == null)
            return HttpNotFound();
        studentRepository.Delete(s);
        return this.RedirectToAction("Index");
    }
...

请帮帮我！由于缺乏最后的努力，我觉得没有成功。我很沮丧

你看过吗

将“

hbm2ddl.keywords

”、“

none

”添加到

Nhibernate.config

中，看看这是否解决了您的问题
