C＃mvc2 nhibernate問題

Question

我的應用程序中有以下映射。該映射是由自定義工具生成的。其他映射生成工作正常，但這是給我一個奇怪的錯誤，我不明白。

這是映射;

<?xml version="1.0" encoding="utf-8"?> 
<!--Generated by NHibernate.Mapping.Attributes on 2010-10-29 08:39:48Z.--> 
<hibernate-mapping xmlns="urn:nhibernate-mapping-2.2"> 
    <class name="Plugin.Twitter.Business.Entities.Tweet, Plugin.Twitter" table="PluginTwitter_Tweet"> 
    <id name="Id" column="Id"> 
     <generator class="guid" /> 
    </id> 
    <property name="TweetMessage" /> 
    <property name="TweetDate" /> 
    <property name="TweetId" /> 
    </class> 
</hibernate-mapping> 

這是我在瀏覽器中獲取的錯誤，當我試圖打開包含映射文件的網站時;

帶它的堆棧跟蹤如下;

    System.Web.HttpRuntime.ProcessRequestNotificationPrivate(IIS7WorkerRequest wr, HttpContext context) +4784373 

我認爲需要注意的是我得到的異常是一個映射異常，如該規則所示;

MappingException: Could not compile the mapping document: Plugin.Twitter.Business.Entities.Hbm.Tweet.hbm.xml] 

我不明白如何以及爲什麼雖然所以我希望有人能告訴我什麼是錯誤的手段，我怎麼能解決這個問題。我有映射標記爲嵌入式資源。

更新： 我們在應用程序中使用以下hibernate.cfg.xml文件。

<?xml version="1.0" encoding="utf-8" ?> 
<hibernate-configuration xmlns='urn:nhibernate-configuration-2.2'> 
    <session-factory> 
    <property name="show_sql">true</property> 
    <property name="dialect">NHibernate.Dialect.MsSql2008Dialect</property> 
    <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property> 
    <property name="connection.connection_string_name">NHibernate</property> 
    <property name="current_session_context_class">managed_web</property> 
    <property name='proxyfactory.factory_class'>NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu</property> 
    <!--Needed for NH Profiler--> 
    <property name="generate_statistics">false</property> 
    </session-factory> 
</hibernate-configuration> 

Answer 1

這與您的映射關係不大。

它說：「找不到在配置方言」，因此機會是很大的，你是不是在指定配置方言......

編輯：映射沒有方言做工精細，只要他們的PK一代是「本土」或「序列」。這個映射使用「guid」，這需要一個方言。

但是，你應該始終將方言屬性來獲取其他配置屬性正確的默認值（而無需手動指定它們）...
