NHibernate-can'；编译映射文件

这是我的域类：

public class User
{
    public Guid id { get; set; }

    public string firstName { get; set; }

    public string lastName { get; set; }

    public string mailAddress { get; set; }
}

这是我的映射文件：

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" assembly="Test" namespace="Test.model">

  <class name="User" >
    <id name="id">
      <generator class="guid"/>
    </id>
    <property name="firstName"  />
    <property name="lastName" />
    <property name="mailAddress" />
  </class>

</hibernate-mapping>

我得到以下例外情况： 无法编译映射文档：data/mapping/User.hbm.xml

我不明白为什么

请提供帮助。

您实体的任何C#财产必须声明为虚拟。以这种方式更改您的类：

public class User
{
    public virtual Guid id { get; set; }
    public virtual string firstName { get; set; }
    public virtual string lastName { get; set; }
    public virtual string mailAddress { get; set; }
}

给出堆栈跟踪，以便查看嵌套异常，很容易检测出确切的原因。

<mapping file="data/mapping/User.hbm.xml" />

 var configuration = new Configuration();
 configuration.Configure();

 _sessionFactory = configuration.BuildSessionFactory();

public class User
{
    public virtual Guid id { get; set; }
    public virtual string firstName { get; set; }
    public virtual string lastName { get; set; }
    public virtual string mailAddress { get; set; }
}
