Nhibernate 3.1.NET4.0-从查询列表中获取复合Id

我有一个MS SQL db，其中的表具有复合id

这是我的xml配置文件：

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"
assembly="SimpleMapping.Domain"
namespace="SimpleMapping.Domain">
  <class name="TabMaster" table="TabMaster">
    <composite-id class="TabMasterCompositeKey">
      <key-property column="Configuration" name="Configuration" type="AnsiString" />
      <key-property column="ResolutionType" name="ResolutionType" type="int" />
    </composite-id>
    <property name="Description" column="Description" type="AnsiString" />
    <property name="Title" column="Title" type="AnsiString" />
    <property name="IdResolutionFileDes" column="idResolutionFileDes" type="AnsiString" />
    <property name="WorkflowType" column="WorkflowType" type="AnsiString" />
    <property name="ViewAllStep" column="ViewAllStep" type="AnsiString" />
    <property name="ManagedData" column="ManagedData" type="AnsiString" />
  </class>
</hibernate-mapping>

及

在我的主要工作中，我尝试在表中列出以下元素：

namespace SimpleMapping.Console
{
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using System.Text;
    using NHibernate;
    using NHibernate.Cfg;
    using SimpleMapping.Domain;

    class Program
    {
        static void Main(string[] args)
        {
            ISessionFactory sessionFactory = new Configuration().Configure().BuildSessionFactory();

            using (ISession session = sessionFactory.OpenSession())
            {
                using (ITransaction tx = session.BeginTransaction())
                {

                    IQuery query = session.CreateQuery("from TabMaster");

                    foreach (TabMaster tm in query.List<TabMaster>())
                        System.Console.WriteLine(string.Format("ID: {0}\nConfiguration: {1}\nManagedData: {2}\n", tm.Configuration, tm.Description, tm.ManagedData));

                    tx.Commit();
                    session.Close();
                }
            }

            System.Console.ReadKey();
        }
    }
}

我可以看到不是键的参数。 所以我可以看到Description和ManagedData，但看不到tm.Configuration：堆栈中的每个记录都设置为Null

有什么问题吗

我认为这与复合id规则有关

谢谢你的回复

您应该将复合键命名为：

<composite-id class="TabMasterCompositeKey" name="TheKey">
      <key-property column="Configuration" name="Configuration" type="AnsiString" />
      <key-property column="ResolutionType" name="ResolutionType" type="int" />
    </composite-id>

这样，您就可以看到实体上的单键属性。

非常感谢！它起作用了！

        static void Main(string[] args)

            using (ISession session = sessionFactory.OpenSession())
            {
                using (ITransaction tx = session.BeginTransaction())
                {

                    IQuery query = session.CreateQuery("from TabMaster");

                    foreach (TabMaster tm in query.List<TabMaster>())
                        System.Console.WriteLine(string.Format("ID: {0}\nConfiguration: {1}\nManagedData: {2}\n", tm.Configuration, tm.Description, tm.ManagedData));

                    tx.Commit();
                    session.Close();
                }
            }

            System.Console.ReadKey();
        }
    }
}

      <key-property column="Configuration" name="Configuration" type="AnsiString" />
      <key-property column="ResolutionType" name="ResolutionType" type="int" />
    </composite-id>

public class TabMaster
    {
        public virtual TabMasterCompositeKey TheKey { get; set; }

        public virtual string Description { get; set; }
        public virtual string Title { get; set; }
        public virtual string IdResolutionFileDes { get; set; }
        public virtual string WorkflowType { get; set; }

    }
