NHibernate启用log4net [英] NHibernate Enabling log4net

问题描述

我已启用log4net并运行我的应用程序，但该应用程序出现了异常.

I have enabled log4net and run my app which is giving an exception.

但是日志文件为空.

NHibernate不会记录有关异常的信息吗?

Doesn't NHibernate log info about the exception???

推荐答案

您需要配置log4net.仅通过将log4net dll添加到项目中就不会记录任何内容.您需要创建附加程序以指定所有登录名应定向到的位置.创建一个像这样的xml文件:

You need to configure log4net. Just by adding log4net dll to the project doesn't log anything. You need to create appenders to specify where all the loggin should be directed to. Create a xml file like this one:

<log4net>  
    <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">  
        <file value="Logs\Trace.log" />  
        <appendToFile value="true" />  
        <rollingStyle value="Composite" />  
        <maxSizeRollBackups value="30" />  
        <maximumFileSize value="1000KB" />  
        <layout type="log4net.Layout.PatternLayout">  
            <conversionPattern value="%date [%thread] %-5level - %message%newline" />  
        </layout>  
        <threshold value="DEBUG"/>  
    </appender>  
    <root>  
        <appender-ref ref="RollingFileAppender" />  
    </root>  
</log4net>  

...并在启动应用程序时对其进行配置:

...and configure it when starting up the application:

   public static void Main()
   {  
      var logconfig = new System.IO.FileInfo(PATH_TO_LOG_CONFIG);  
      if(logconfig.Exists)  
      {  
          log4net.Config.XmlConfigurator.ConfigureAndWatch(logconfig);  
      }  
   }
