c# - 似乎无法使 nhibernate 与 mysql 一起工作

Question

我在设置 NHibernate 来使用 mysql 数据库时遇到问题......错误:

[InvalidProgramException: JIT Compiler encountered an internal limitation.] NHibernate.Cfg.MappingSchema.HbmId.get_Type() +0 NHibernate.Cfg.XmlHbmBinding.ClassIdBinder.BindId(HbmId idSchema, PersistentClass rootClass, Table table) +477 NHibernate.Cfg.XmlHbmBinding.RootClassBinder.Bind(HbmClass classSchema, IDictionary2 inheritedMetas) +1901

Web.config:

 <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
     <reflection-optimizer use="false" />
     <session-factory>
       <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
       <property name="connection.driver_class">NHibernate.Driver.MySqlDataDriver</property>

       <property name="dialect">NHibernate.Dialect.MySQL5Dialect</property>
       <mapping assembly="DomainModel" />
     </session-factory>
   </hibernate-configuration>

映射文件:

   <?xml version="1.0" encoding="utf-8" ?>
   <hibernate-mapping xmlns="urn:nhibernate-mapping-2.2" 
   namespace="WebGest.NET.DomainModel"
   assembly="DomainModel">
     <class name="Operator" table="s_operatori">

       <id name="IdOperator" column="IdOperator" unsaved-value="0">
         <generator class="native" />
       </id>

       <property name="User">
         <column name="User" not-null="true" />
       </property>

       <property name="Parola">
         <column name="Parola" not-null="false" />
       </property>

       <property name="FlagActiv">
         <column name="FlagActiv" not-null="true" />
       </property>
     </class>
   </hibernate-mapping>

CS:

   namespace WebGest.NET.DomainModel
   {
       public partial class Operator
       {
           public virtual int IdOperator { get; set; }
           public virtual string User { get; set; }
           public virtual string Parola { get; set; }
           public virtual bool FlagActiv { get; set; }
           public Operator() { }
       }
   }

那我做错了什么？

此外，asp.net 站点与包含 NHibernate 和 mysql 引用的“domainmodel”项目位于一个单独的项目中，这两个项目位于同一解决方案中。

尝试揭示异常的内部异常:

{"Could not compile the mapping document: WebGest.NET.DomainModel.Mappings.XML.Operator.hbm.xml"}

将会有明确的信息、明确的消息。例如:

{"persistent class WebGest.NET.DomainModel.Operator, DomainModel not found"}

这意味着具有 Operator 类的项目未加载。如果 Operator 未在 DomainModel 程序集中定义，情况就是如此……

但我在这里猜测.. 内部异常会清楚地告诉你...
