asp.net-mvc - 为什么 log4net 不记录 nhibernate 信息

Question

我的 Visual Studio 解决方案包含:

[DLL] Sol.DataAccess (NHibernate sessionManager)

[DLL] Sol.Core(模型和存储库)

[MVC] Sol.WebMvc( Controller ， View )

我的所有应用程序包含(nhibernate.dll [v3.0] 和 log4net.dll[v1.2.10])

我有 3 个配置:

网络配置:

<configuration>
    <configSections>
         <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821" requirePermission="false" />
         <section name="hibernate-configuration" type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"/>
    </configSections>
</configuration>

nhibernate.config:

<hibernate-configuration  xmlns="urn:nhibernate-configuration-2.2" >
  <session-factory name="...">
    <property name="connection.driver_class">NHibernate.Driver.SqlClientDriver</property>
    <property name="connection.connection_string_name">...</property>
    <property name="adonet.batch_size">10</property>
    <property name="show_sql">true</property>
    <property name="generate_statistics">true</property>
    <property name="dialect">NHibernate.Dialect.MsSql2008Dialect</property>
    <property name="use_outer_join">true</property>
    <property name="max_fetch_depth">2</property>
    <property name="command_timeout">60</property>
    <property name="adonet.batch_size">25</property>
    <property name="query.substitutions">true 1, false 0, yes 'Y', no 'N'</property>
    <property name="proxyfactory.factory_class">NHibernate.ByteCode.Castle.ProxyFactoryFactory, NHibernate.ByteCode.Castle</property>
    <property name="current_session_context_class">web</property>
    <property name="cache.use_query_cache">true</property>
    <property name="cache.provider_class">NHibernate.Caches.SysCache2.SysCacheProvider, NHibernate.Caches.SysCache2</property>
    <mapping assembly="..."/>
  </session-factory>
</hibernate-configuration>

和 log4net.config:

<log4net>

全局.cs:

protected void Application_Start()

       ...
        // Configuration

        #region log4net
        // log4net.config
        System.IO.FileInfo fi = new System.IO.FileInfo(Server.MapPath("~/log4net.config"));
        if (fi != null && fi.Exists)
        {
            // Code that runs on application startup
            log4net.Config.XmlConfigurator.Configure(fi);
        }

        // web.config
        //log4net.Config.XmlConfigurator.Configure();

        // set properti hostName
        log4net.GlobalContext.Properties["hostName"] = Dns.GetHostName();
        #endregion

        #region NHibernate
        //HibernatingRhinos.Profiler.Appender.NHibernate.NHibernateProfiler.Initialize();
        var factory = NHibernateSessionManager.ConfigureFromFile(Server.MapPath("~/hibernate.config"));
        #endregion
    }

在我的测试 Controller 中，我有:

public class TestController : BaseController
    {
        [NHibernateSession]
        public ActionResult Index()
        {
             Logger.Error("fake error", new Exception());
        }
     }

在我的日志文件 - Logs/Logs.txt 中:

2011-03-11 18:19:23,097 [8] ERROR System.Web.Mvc.Controller [(null)] - fake error
System.Exception: Exception of type 'System.Exception' was thrown.

问题:
为什么 log4net 不记录 NHibernate 信息(信息、调试 ....)

这些 dll 的版本不兼容吗？

Answer 1

我创建了一个空的 ASP.Net MVC3 项目。并在尝试解决此问题时浪费了很多时间。
我发现了 VS2010 的错误。 当您在项目中引用它时，Visual Studio 2010 不会在 bin 中复制 dll。

我把 log4net.dll 手册放在我的 bin 文件夹中并且工作正常。 (有趣的是 Logger.Error("fake error") 在 bin 文件夹中没有 log4net.dll 的情况下工作正常......)
