无法编译映射文件：NHibernate

Question

我对 NHibernate 完全陌生。我看到许多标题相同的问题，但我找不到确切的错误。我在 SQL Server 2012 中使用 NHibernate。

我的 hibernate.cfg.xml :

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
    <session-factory>
        <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
        <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
        <property name="dialect">NHibernate.Dialect.MsSql2012Dialect</property>
        <property name="connection.connection_string">Data Source=.\SQLEXPRESS;Initial Catalog=cafePOSdb;Integrated Security=True;</property>
        <property name="show_sql">true</property>
        <mapping assembly="CafePOS" />
    </session-factory>
</hibernate-configuration>

我的映射模型：

using System;
using System.Text;
using System.Collections.Generic;

namespace CafePOS
{
    public class CafeTableGroup 
    {
        //properties here
    }
}

我的 hbm.xml 文件：

<?xml version="1.0" encoding="utf-8"?>
<hibernate-mapping assembly="CafePOS" namespace="CafePOS" xmlns="urn:nhibernate-mapping-2.2">
  <class name="cafe_table_group" table="cafe_table_group" lazy="true" >
   <!--properties here -->
  </class>
</hibernate-mapping>

我的 SessionFactory class:

namespace XXXXXX
{
    public sealed class SessionFactory
    {
        private static volatile ISessionFactory iSessionFactory;
        private static object syncRoot = new Object();
        public static ISession OpenSession
        {
            get
            {
                if (iSessionFactory == null)
                {
                    lock (syncRoot)
                    {
                        if (iSessionFactory == null)
                        {
                            Configuration configuration = new Configuration();
                         Assembly assembly = Assembly.GetCallingAssembly();
                             configuration.AddAssembly(assembly);
                           iSessionFactory = configuration.BuildSessionFactory();
                        }
                    }
                }
                return iSessionFactory.OpenSession();
            }
        }
    }
}

这是我尝试实现的功能：

public static string Add(CafeTableGroup group)
{
    using (ISession session = SessionFactory.OpenSession)
    {
        using (ITransaction transaction = session.BeginTransaction())
        {
            try
            {
                session.Save(group);
                transaction.Commit();
                return "1";
            }
            catch (Exception ex)
            {
                transaction.Rollback();
                session.Close();
                throw ex.InnerException;
            }
        }
    }
}

我在线上出错

configuration.AddAssembly(assembly);

显示标题中的错误：

Could not compile the mapping document: NHibernate

内部异常消息：

Could not find the dialect in the configuration

提前致谢。

您应该在根文件夹中有文件 hibernate.cfg.xml。

文件的示例内容为：

<?xml version="1.0" encoding="utf-8" ?>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
    <session-factory>
        <property name="connection.provider">NHibernate.Connection.DriverConnectionProvider</property>
        <property name="dialect">Netsis.Framework.Persister.Hibernate.Dialect.NMsSql2008Dialect, Netsis.Framework.Persister</property>
        <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
        <property name="connection.connection_string">Data Source=localhost;Initial Catalog=CRM;Persist Security Info=True;User ID=user;Password=pass</property>
        <property name="proxyfactory.factory_class">Netsis.Framework.Persister.Hibernate.Proxy.PropertyReaderProxyFactoryFactory,Netsis.Framework.Persister</property>
        <property name="show_sql">True</property>
        <property name="format_sql">True</property>
        <property name="adonet.batch_size">30</property>  
    </session-factory>
</hibernate-configuration>

Answer 2

您的 class 名字不是 cafe_table_group，而是 CafeTableGroup。

你能试试把你的 hbm.xml 改成

<class name="CafeTableGroup" table="cafe_table_group" lazy="true">
