c# - Log4net - 多个附加程序

问题描述

我目前有两个附加程序，一个用于登录文件，另一个用于登录数据库。ado net appender 不工作，它没有在表中记录任何内容。然而，滚动文件附加程序工作得很好。它登录文件。如果我删除滚动文件附加程序，数据库中的日志记录工作得很好。

这是我的 app.config 文件的一部分：

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<sectionGroup name="common">
  <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
</sectionGroup>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
    <!-- For more information on Entity Framework configuration, visit http://go.microsoft.com/fwlink/?LinkID=237468 -->
 </configSections>
<connectionStrings>
    <add name="Log4NetDBConnection" connectionString="Data Source=localhost;Initial Catalog=DataProcessing;UID=dpp-user;PWD=dpp-user" providerName="System.Data.SqlClient" />


 <common>
<logging>
  <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4Net1211">
    <arg key="configType" value="INLINE" />
    </factoryAdapter>
   </logging>
   </common>
  <log4net configSource="App.log4net.config" />
    <dependentAssembly>
    <assemblyIdentity name="Common.Logging.Core" publicKeyToken="af08829b84f0328e" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-3.3.0.0" newVersion="3.3.0.0" />
  </dependentAssembly>

    <assemblyIdentity name="Common.Logging" publicKeyToken="af08829b84f0328e" culture="neutral" />
    <bindingRedirect oldVersion="0.0.0.0-3.3.0.0" newVersion="3.3.0.0" />
  </dependentAssembly>
</assemblyBinding>

这是我的 App.Log4net.config 文件：

<log4net>

<level value="ERROR" />
<level value="WARN" />
<appender-ref ref="AdoNetAppender" />

<parameter>
  <parameterName value="@exception" />
  <dbType value="String" />
  <size value="2000" />
  <layout type="log4net.Layout.ExceptionLayout" />
</parameter>


<!-- <root>
<level value="DEBUG" />

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">

<layout type="log4net.Layout.PatternLayout">
  <conversionPattern value="%date [%thread] %level %logger - 
%message%newline%exception" />
</layout>
</appender> -->

</log4net>

如您所见，我对滚动文件附加程序进行了注释，否则它只会登录文件。我究竟做错了什么？我可以一起使用这两个附加程序吗？

解决方案

我怀疑您走在正确的轨道上，看起来两个附加程序都需要在同一个根目录中指定，请参见下面的示例和链接：

<root>
<level value="ERROR" />
<level value="WARN" />
<appender-ref ref="AdoNetAppender" />
<level value="DEBUG" />
<appender-ref ref="RollingFileAppender" />
</root>

log4net 的文件和数据库多重配置
