程序集属性中的Log4net配置不会加载配置文件

Question

我的bin目录中有以下文件Log4net.config:

<?xml version="1.0" encoding="utf-8" ?>
<log4net xmlns="urn:log4net">
    <appender name="FileAppender" type="log4net.Appender.FileAppender">
        <param name="file" value="MyLogFile.log"/>
        <param name="appendToFile" value="false"/>
        <layout type="log4net.Layout.PatternLayout">
            <param name="ConversionPattern" value="%date (%logger) [%5level] - %message" />
        </layout>
    </appender>
    <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
        <layout type="log4net.Layout.PatternLayout">
            <param name="ConversionPattern" value="%date (%logger) [%5level] - %message" />
        </layout>
    </appender>
    <root>
        <level value="DEBUG" />
        <appender-ref ref="FileAppender" />
        <appender-ref ref="ConsoleAppender"/>
    </root>
    <logger name="NHibernate" additivity="false">
        <level value="WARN"/>
    </logger>
</log4net>

以及AssemblyInfo.cs文件中的以下代码:

using System.Reflection;
using System.Runtime.CompilerServices;
using System.Runtime.InteropServices;

[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyTitle("My Project")]
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Log4net.config", Watch = true)]

当我运行程序时,我得到以下log4net调试输出:

log4net: log4net assembly [log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821]. Loaded from [D:\Data\Projects\Active\Clients\MyProject\src\MyProject.Importer\bin\Debug\log4net.dll]. (.NET Runtime [4.0.30319.1] on Microsoft Windows NT 6.1.7600.0)

log4net: Hierarchy: Shutdown called on Hierarchy [log4net-default-repository]

Log4net加载,但似乎没有处理我的配置文件.当我在AssemblyInfo.cs中注释掉该属性并在程序初始化期间运行以下代码时,它按预期工作:

var log4netConfig = "Log4net.config";
var log4netInfo = new FileInfo(log4netConfig);
log4net.Config.XmlConfigurator.ConfigureAndWatch(log4netInfo);

我究竟做错了什么？我想从AssemblyInfo.cs加载.

Answer 1

我也遇到了这种提升log4net的方法.该文件说,你要拨打电话在你的应用程序启动非常早

如果使用配置属性,则必须调用log4net以允许它读取属性.对LogManager.GetLogger的简单调用将导致读取和处理调用程序集上的属性.因此,必须在应用程序启动期间尽早进行日志记录调用,当然在加载和调用任何外部程序集之前.

尝试将记录器放在启动应用程序的同一个类中(program.cs,app.xaml,等等).例如

private static readonly ILog Log = LogManager.GetLogger(typeof(Program));

并且对于踢,任何对日志的调用(即使是在追加过程中过滤或评估的日志,它也应该强制log4net来评估你的存储库/层次结构).

static Program()
{
    Log.Debug("Application loaded.");
}

最后我找到了简单的解决方案,你可以在那里得到帮助

1. 启动函数中的Global.asax

    protected void Application_Start()
    {
      log4net.Config.XmlConfigurator.Configure();
    }
   

2. 在任何使用类级别日志记录的类中

添加命名空间

using log4net;

在类级别添加此代码行

private static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

3. 在任何动作调用中使用日志功能

   log.Error("test error q111..");
   

4. 组态

   <configuration>
   <configSections>
   <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net " />
   </configSection>
   <log4net debug="true">
   
   <!--AdoNet appender is use for write log file into sql server-->
   <appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">

     </parameter>
   </appender>
   <!--Add appender which you want to use, You can add more then one appender . Like if you want save log both plain text or sql server ,Add both appender.-->

   </log4net>
   
   <appSettings>
   <add key="log4net.Internal.Debug" value="true"/>

它可以帮助所有人,并且易于使用.谢谢
