Log4net-多个追加程序

Question

I currently have two appenders, one is for logging in a file and the other is for logging in a database. The ado net appender is not working, it's not logging anything in the table. The rolling file appender however, works just fine. It logs in the file. If I remove the rolling file appender, the logging in the database works just fine.

Here's part of my app.config file:

<?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>
  <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>

And here is my App.Log4net.config file:

<log4net>

</appender> -->

</log4net>

As you can see, I have the rolling file appender commented because otherwise it only logs in a file. What am I doing wrong? Can I use these two appenders together?

Answer 1

I suspect your are on the right track, looks like both appenders needs to be specified in the same root see example and link below:

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