NHibernate.MappingException:No persister在程序集中找不到映射文档

Question

很多天以来,我一直在做nhibernate.但今天我陷入了一个令人沮丧的问题,即映射异常.

    <?xml version="1.0" encoding="utf-8" ?>
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" namespace="IPC.Base.Domains" assembly="IPC">
  <class name="MenuItem" table="dbo.COR_MenuItem" default-access="property" default-cascade="save-update" default-lazy="true">
    <cache usage="read-only" region="completelyStatic"/>
    <id name="Id" type="System.Int32">
      <generator class="identity" />
    </id>
    <property name="Name" type="System.String" />
    <property name="Order" column="DisplayOrder" />
    <property name="Key" column="KeyChain" />
    <property name="Route" />
    <property name="ActionMethod" />
    <property name="IsHotlink" />
    <many-to-one name="ParentMenuItem" column="ParentMenuItemId" class="MenuItem" cascade="none"/>
    <bag name="MenuItems" table="dbo.COR_MenuItem" cascade="none">
      <cache usage="read-only" region="completelyStatic"/>
      <key column="ParentMenuItemId" />
      <one-to-many class="MenuItem" />
    </bag>
  </class>
</hibernate-mapping>

我确实有一个映射类如下:

using System;
using System.Collections.Generic;

namespace IPC.Base.Domain
{
    public partial class MenuItem : PersistentObject
    {
        public MenuItem()
        {
            MenuItems = new List<MenuItem>();
        }
        public virtual string Name { get; set; }
        public virtual int? Order { get; set; }
        public virtual string Key { get; set; }
        public virtual string Route { get; set; }
        public virtual string ActionMethod { get; set; }
        public virtual bool IsHotlink { get; set; }
        public virtual IList<MenuItem> MenuItems { get; set; }
        public virtual MenuItem ParentMenuItem { get; set; }

        /// <summary>
        /// only to be used from the menu builder app
        /// </summary>
        /// <param name="id"></param>
        public virtual void SetId(int id)
        {
            Id = id;
        }
    }
}

我在应用程序中运行了以下nHibernate Config.但根据我的经验,nHibernate配置绝对没有问题.

<?xml version="1.0"?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
 <session-factory name="IPC">
  <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
    <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
    <property name="connection.connection_string">**************SQL CONNECTION****************/property>
    <property name="proxyfactory.factory_class">NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property>
    <property name="cache.provider_class">NHibernate.Caches.SysCache.SysCacheProvider, NHibernate.Caches.SysCache</property>
  <property name="cache.use_query_cache">true</property>
    <property name="show_sql">true</property>
    <mapping assembly="IPC"/>
 </session-factory>
</hibernate-configuration>

我使用以下行代码来调用nHibernate会话对象到系统.

static ISessionFactory CurrentFactory
        {
            get
            {
                if (factory == null)
                {
                    Configuration cfg = new Configuration();
                    if (cfgFile == null)
                        cfg = cfg.Configure();
                    else
                        cfg = cfg.Configure(cfgFile);

                    factory = cfg.BuildSessionFactory();
                }
                return factory;
            }
        }
        public static ISession Create()
        {
            var session = CurrentFactory.OpenSession();
            return session;
        }

现在!当我调用以下代码行时,我得到:

public virtual T Get(int id)
        {
            return Session.Get<T>(id);
        }

我已经通过nHibernate日志启用了.以下是日志的基本细节

我已经阅读了几乎所有带有堆栈的帖子!:)甚至谷歌也一样.我到达那里的最后一句话是我的程序集命名问题!我确定我遵循的步骤存在问题.但仍然在寻找那个触发器!

谢谢!提前!!

可能你忘了将你的hbm映射设置为DLL的嵌入资源.
