我怎樣才能NHibernate的領域類映射與現有的表

我目前嘗試使用NHibernate的上一個項目，我沒有權限CREATE TABLE在SQL 2005我怎樣才能NHibernate的領域類映射與現有的表

我不斷收到一個映射錯誤，我的假設是我沒有通過生成表來設置表。假設NHibernate只能成功映射其工具生成的表格，這對我是否公平？

如果不是，我如何確保它適用於現有的表格？

<id name="MeetingID" column="MeetingID" type="int"> 
    <generator class="identity" /> 
</id> 
<property name="Description" /> 
<property name="OwnerNetworkID" /> 
<property name="StartDate" /> 
<property name="EndDate" /> 
<property name="DayStartHour" /> 
<property name="DayStartMinute" /> 
<property name="DayEndHour" /> 
<property name="DayEndMinute" /> 
<property name="BreakStartHour" /> 
<property name="BreakStartMinute" /> 
<property name="BreakEndHour" /> 
<property name="BreakEndMinute" /> 
<property name="IsActive" />

<property name="LastModified" />

你的假設是錯誤的:) NHibernate的作品與現有的表，它創建沒有桌子。你能粘貼你的映射嗎？ – 2010-09-13 16:56:33

@Claudio NHibernate可以創建表，如果你做一個SchemaExport.Create（true，true）; – rebelliard 2010-09-13 17:31:36

@user您能告訴我們一個example嗎？當然可以使用現有的表格，我們只需要知道你犯了什麼錯誤。 :) – rebelliard 2010-09-13 17:32:49

我發現我的問題的根源。

該錯誤是由於在調用AddAssembly（typeof（Type））之前未調用Configure（）方法導致的。當我創建一個SessionFactory對象時會發生這種情況。

下面是該解決方案的VB例子：

以前

Private Shared ReadOnly Property SessionFactory() As ISessionFactory 
     Get 
      If _sessionFactory Is Nothing Then 
       Dim configuration As New Configuration 
        configuration.AddAssembly(GetType(Meeting).Assembly) 
       _sessionFactory = configuration.BuildSessionFactory 

      End If 
      Return _sessionFactory 
     End Get 
    End Property

後

Private Shared ReadOnly Property SessionFactory() As ISessionFactory 
     Get 
      If _sessionFactory Is Nothing Then 
       Dim configuration As New Configuration 

       //Was missing 
       configuration.Configure() 
       //Configure 
       configuration.AddAssembly(GetType(Meeting).Assembly) 
       _sessionFactory = configuration.BuildSessionFactory 

      End If 
      Return _sessionFactory 
     End Get 
    End Property
