未配置ProxyFactoryFactory

Question

将此示例作为基本示例，我创建了应用程序，但当我执行此应用程序时，将得到以下错误。

未配置ProxyFactoryFactory。使用可用的proxyfactory.factory_class提供程序之一初始化会话工厂配置部分的“NHibernate.ByteCode”属性。示例: NHibernate.ByteCode.LinFu.ProxyFactoryFactory，NHibernate.ByteCode.LinFu示例: NHibernate.ByteCode.Castle.ProxyFactoryFactory，NHibernate.ByteCode.Castle

下面是我正在使用的代码片段。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using NHibernate;
using NHibernate.Cfg;

public partial class _Default : System.Web.UI.Page 
{
    protected void Page_Load(object sender, EventArgs e)
    {
        Configuration cfg = new Configuration();
        cfg.AddAssembly("NHibernate");

        ISessionFactory factory = cfg.BuildSessionFactory();
        ISession session = factory.OpenSession();
        ITransaction transaction = session.BeginTransaction();
        User newUser = new User();
        newUser.Id = "joe_cool";
        newUser.UserName = "Joseph Cool";
        newUser.Password = "abc123";
        newUser.EmailAddress = "joe@cool.com";
        newUser.LastLogon = DateTime.Now;

        // Tell NHibernate that this object should be saved
        session.Save(newUser);

        // commit all of the changes to the DB and close the ISession
        transaction.Commit();
        session.Close();    
    }
}

我的app.config文件看起来就像

    <?xml version="1.0" encoding="utf-8" ?>
    <configuration>
      <configSections>
        <section
          name="nhibernate"
          type="System.Configuration.NameValueSectionHandler, System, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
        />
      </configSections>

      <nhibernate>
        <add
          key="hibernate.connection.provider"
          value="NHibernate.Connection.DriverConnectionProvider"
        />
        <add
          key="hibernate.dialect"
          value="NHibernate.Dialect.MsSql2000Dialect"
        />
        <add
          key="hibernate.connection.driver_class"
          value="NHibernate.Driver.SqlClientDriver"
        />
        <add
          key="hibernate.connection.connection_string"
          value="Server=localhost;initial catalog=nhibernate;Integrated Security=SSPI"
        />
        <!--<add value="nhibernate.bytecode.castle.proxyfactoryfactory, nhibernate.bytecode.castle" key="proxyfactory.factory_class" />-->
        <!--<property name="proxyfactory.factory_class">NHibernate.ByteCode.Linfu.ProxyFactoryFactory, NHibernate.ByteCode.Linfu</property>-->
<!-- I have tried both the lines but still getting the same error -->
      </nhibernate>
    </configuration>

我有LinFu.DynamicProxy.dll而不是linfu.dll。它能用吗？如果没有，那么我从哪里得到这个linfu.dll？或者还有其他的解决办法？

Answer 1

假设您拥有NHibernate 2.1 Alpha3，将LinFu.DynamicProxy.dll和NHibernate.ByteCode.LinFu.dll从\Required_For_LazyLoading\LinFu复制到bin (或引用)

那么您的配置行应该可以工作：

<add key="proxyfactory.factory_class" value="NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu" />

顺便说一句，我更喜欢配置hibernate-configuration节块。

编辑:这是我的web配置中的相关部分，如果您想使用hibernate-configuration而不是键/值对来设置。

另外，只需将hibernate-configuration部件放入自己的名为hibernate.cfg.xml的文件即可。然后可以使用下载中的xsd nhibernate-configuration.xsd来验证您的配置。

<configSections>
    <section name="hibernate-configuration"   type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"/>
</configSections>
<hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
    <session-factory>
        <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
        <property name="default_schema">kennelfinder.dbo</property>
        <property name="connection.provider">
            NHibernate.Connection.DriverConnectionProvider
        </property>
        <property name="proxyfactory.factory_class">
            NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu
        </property>
        <property name="connection.connection_string">{Your connection string}</property>
        <property name="show_sql">false</property>
        <property name="connection.driver_class">
            NHibernate.Driver.SqlClientDriver
        </property>
        <property name="connection.isolation">ReadCommitted</property>
        <property name="use_proxy_validator">true</property>
        <mapping assembly="KennelFinder"/>
    </session-factory>
</hibernate-configuration>

Answer 2

我们实际上使用了Castle，并具有以下内容。

<property name='proxyfactory.factory_class'>NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>

在此之后，只需确保NHibernate城堡延迟加载目录中的所有文件都在bin中。

LinFu.DynamicProxy.dll是不够的。您还需要NHibernate.ByteCode.Linfu.dll (以及潜在的其他)。

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"/>
    </configSections>
    <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
        <session-factory>
            <property name="dialect">NHibernate.Dialect.MsSql2005Dialect</property>
            <property name="connection.provider"> NHibernate.Connection.DriverConnectionProvider </property>
            <property name="proxyfactory.factory_class"> NHibernate.ByteCode.LinFu.ProxyFactoryFactory, NHibernate.ByteCode.LinFu </property>
            <property name="connection.connection_string">Server=(local);database=HelloNHibernate;Integrated Security=SSPI;</property>
            <property name="show_sql">false</property>
            <property name="connection.driver_class"> NHibernate.Driver.SqlClientDriver </property>
            <property name="connection.isolation">ReadCommitted</property>
            <property name="use_proxy_validator">true</property>
        </session-factory>
    </hibernate-configuration>
</configuration>

将LinFu.DynamicProxy.dll和NHibernate.ByteCode.LinFu.dll复制到NHibernate的文件夹，并将相同的DLL文件添加到项目引用中。
