Nhibernate映射鑑別器「錯誤的類例外」

我正在爲學校做一個NHibernate演示，但我遇到了一個我無法解決的問題。你有一張票和票務回覆。硬件標籤繼承票證。當執行ReadTicket方法，我收到了WrongclassException說Nhibernate映射鑑別器「錯誤的類例外」

「對象沒有指定的子類：SC.BL.Domain.Ticket （鑑別是：」）」

如果有人能幫助我，我會很高興

public class Ticket 
    { 
    public virtual int AccountId { get; set; } 
    public virtual DateTime DateOpened { get; set; } 
    [Required] 
    [MaxLength(100, ErrorMessage = "Er zijn maximaal 100 tekens toegestaan")] 
    public virtual string Text { get; set; } 
    public virtual int TicketNumber { get; set; } 
    public virtual TicketState State { get; set; } 
    public virtual IList<TicketResponse> Responses { get; set; } 

    } 
public class HardwareTicket : Ticket 
    { 
    [RegularExpression("^(PC-)[0-9]+")] 
    public virtual string DeviceName { get; set; } 
    }

庫：

public class TicketRepository : ITicketRepository 
     { private static ISessionFactory mySessionFactory; 

     Private static ISession mySession; 

     public TicketRepository() 
     { 
      if (mySessionFactory == null) 
      { 
      var configuration = new Configuration().Configure("hibernate.cfg.xml"); 
      configuration.AddAssembly(typeof(Ticket).Assembly); 
      configuration.AddAssembly(typeof(TicketResponse).Assembly); 
      mySessionFactory = configuration.BuildSessionFactory(); 
      } 
     } 
public Ticket ReadTicket(int ticketNumber) 
    { 
     using (mySession = mySessionFactory.OpenSession()) 
     { 
     var ticket = mySession.QueryOver<Ticket>().Where(x => x.TicketNumber == ticketNumber).SingleOrDefault(); 
     return ticket; 
     } 
    }

映射：

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" 
        assembly="SC.BL.Domain" 
       namespace ="SC.BL.Domain"> 


    <class name="Ticket" table="Ticket" lazy ="true"> 
    <id name="TicketNumber"> 
     <generator class="identity"> </generator> 
    </id> 
    <discriminator column="Discriminator" type="System.String" not-null="true"/> 
    <property name="AccountId"></property> 
    <property name="Text"></property> 
    <property name="DateOpened"></property> 
    <property name="State"></property> 


    <bag name="Responses" lazy="true" inverse="true" 
          batch-size="25" cascade="all-delete-orphan"> 
     <key column="TicketNumber" /> 
     <one-to-many class="TicketResponse" /> 
    </bag> 

    <subclass name="HardwareTicket" discriminator-value ="HardwareTicket" > 
     <property name="DeviceName" not-null="false"></property> 
    </subclass> 

    <subclass name="Ticket" discriminator-value ="Ticket" > 

    </subclass> 
    </class> 
</hibernate-mapping>

票是您的主要基類。你不能在你的映射中添加相同的子類。

<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" 
        assembly="SC.BL.Domain" 
       namespace ="SC.BL.Domain"> 


    <class name="Ticket" table="Ticket" lazy ="true"> 
    <id name="TicketNumber"> 
     <generator class="identity"> </generator> 
    </id> 
    <discriminator column="Discriminator" type="System.String" not-null="true"/> 
    <property name="AccountId"></property> 
    <property name="Text"></property> 
    <property name="DateOpened"></property> 
    <property name="State"></property> 


    <bag name="Responses" lazy="true" inverse="true" 
          batch-size="25" cascade="all-delete-orphan"> 
     <key column="TicketNumber" /> 
     <one-to-many class="TicketResponse" /> 
    </bag> 

    <subclass name="HardwareTicket" discriminator-value ="HardwareTicket" > 
     <property name="DeviceName" not-null="false"></property> 
    </subclass> 
    </class> 
</hibernate-mapping>
