用NHibernate映射Northwind客户的问题

作为NHibernate(2.1.0)的初学者,我正在尝试使用著名的Northwind数据库设置我的第一个单元测试。测试过程如下(配置文件可在本问题末尾找到):

ISessionFactory sessionFactory=new Configuration().BuildSessionFactory();
ISession session=sessionFactory.OpenSession();
IList<Customer> list=session.CreateCriteria<Customer>().List<Customer>();
Assert.AreEqual(91, list.Count);

问题是 list.Count 总是0。

• 我试图通过提供自己的会话来打开会话。 IDbConnection 在SQL Server 2008上,MS Access和sqlite(我百分之百肯定数据库设置和连接有效)无效。
• 我试图让生成的SQL显示在VS2008输出窗口上(请参阅本文底部的配置文件),但从来没有显示过。

我只能在这个阶段猜测我的配置是错误的,但我不知道如何修复它。

• App.CONFIG :

  <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
    <session-factory>
      <property name="dialect">NHibernate.Dialect.SQLiteDialect</property>
      <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
      <property name="connection.driver_class">NHibernate.Driver.SQLite20Driver</property>
      <property name="connection.connection_string">Data Source=S:\Work\SVN\src\Northwind\SQL\Northwind.db</property>
      <property name='proxyfactory.factory_class'>NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property>
      <property name="show_sql">true</property>
    </session-factory>
  </hibernate-configuration>
  <log4net>
    <appender name="DebugSQL" type="log4net.Appender.TraceAppender">
      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />
      </layout>
    </appender>
    <root>
      <level value="DEBUG" />
      <appender-ref ref="DebugSQL" />
    </root>
  </log4net>
  

• 客户CS :

  namespace Northwind.DomainModel.NHibernate
  {
      public class Customer
      {
          public string CustomerID { get; set; }
          public string CompanyName { get; set; }
          public string ContactName { get; set; }
          public string ContactTitle { get; set; }
          public string Address { get; set; }
          public string City { get; set; }
          public string Region { get; set; }
          public string PostalCode { get; set; }
          public string Country { get; set; }
          public string Phone { get; set; }
          public string Fax { get; set; }
      }
  }
  

• 客户.hbm.xml :

  <hibernate-mapping
    xmlns="urn:nhibernate-mapping-2.2"
    assembly="Northwind.DomainModel"
    namespace="Northwind.DomainModel.NHibernate"
  >
    <class name="Customer" table="Customers">
      <id name="CustomerID" column="CustomerID" type="String" length="5">
        <generator class="assigned" />
      </id>
      <property name="CompanyName" />
      <property name="ContactName" />
      <property name="ContactTitle" />
      <property name="Address" />
      <property name="City" />
      <property name="Region" />
      <property name="PostalCode" />
      <property name="Country" />
      <property name="Phone" />
      <property name="Fax" />
    </class>
  </hibernate-mapping>
