1、log4net 单独配置
log4net支持多种格式的日志输出，我这里只配置输出到本地的txt文件这种格式。
<log4net>
<root>
<appender-ref ref="RollingFileAppender" />
</root>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="..\\Data\\Log\\Log.txt" />
<param name="AppendToFile" value="true" />
<param name="MaxSizeRollBackups" value="10" />
<param name="MaximumFileSize" value="5MB" />
<param name="RollingStyle" value="Size" />
<param name="StaticLogFileName" value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%n[时间]:%d%n[级别]:%p%n[内容]:%m%n" />
</layout>
</appender>
</log4net>
2、Common.Logging 配置
<configSections>
<sectionGroup name="common">
<section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging"/>
</sectionGroup>
</configSections> <common>
<logging>
<factoryAdapter type="Common.Logging.Simple.ConsoleOutLoggerFactoryAdapter, Common.Logging">
<arg key="showLogName" value="true"/>
<arg key="showDataTime" value="true"/>
<arg key="level" value="INFO"/>
<arg key="dateTimeFormat" value="HH:mm:ss:fff"/>
</factoryAdapter>
</logging>
</common>
3、Common.Logging+log4net+ Common.Logging.Log4Net配置
在联合使用Common.Logging和log4net日志组件时需要注意组件之间的版本是否匹配。

组件下载：https://github.com/net-commons/common-logging/tree/2.3.0.RC1
<configSections>
<sectionGroup name="common">
<section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging"/>
</sectionGroup>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections> <common>
<logging>
<factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter,Common.Logging.Log4Net1210">
<arg key="configType" value="INLINE" />
</factoryAdapter>
</logging>
</common> <log4net>
<root>
<appender-ref ref="RollingFileAppender" />
</root> <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger %ndc - %message%newline" />
</layout>
</appender> <appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="..\\Data\\Log\\Log.txt" />
<param name="AppendToFile" value="true" />
<param name="MaxSizeRollBackups" value="" />
<param name="MaximumFileSize" value="5MB" />
<param name="RollingStyle" value="Size" />
<param name="StaticLogFileName" value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%n[时间]:%d%n[级别]:%p%n[内容]:%m%n" />
</layout>
</appender> </log4net>
