Log4net 基本样式:
<log4net>
<appender name="LogFileAppender" type="log4net.Appender.FileAppender">
<param name="File" value="Mylog/" />
<param name="AppenderToFile" value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="Header" value="[Header]\r\n" />
<param name="Footer" value="[Footer]\r\n" />
<param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />
</layout>
<!--过滤器:将只记录level为DEBUG与WARN之间的日志-->
<filter type="log4net.Filter.LevelRangeFilter">
<param name="LevelMin" value="DEBUG">
<param name="LevelMax" value="WARN">
</filter>
</appender>
<root>
<!--缺省为DEBUG级别-->
<level value="DEBUG">
<!--声明了在其他地方定义的Appender对象的一个引用-->
<appender-ref ref="LogFileAppender">
</root>
<!-- logger标签不是必须的 Additivity的值缺省是true-->
<logger name="testApp.Logging" additivity="false">
<level value="DEBUG" />
</logger>
</log4net>
Log4net.config
Log4Net配置文件的书写
添加section
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
</configSections>
按日期分隔文件
<!-- 按日期分隔文件 -->
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="D:\\MyLogFiles\\ClientService\log4net\"/>
<!-- 是否在文件中追加 -->
<param name="AppendToFile" value="true"/>
<!-- 最小锁定模型以允许多个进程可以写入同一个文件 -->
<param name="LockingModel" value="log4net.Appender.FileAppender.MinimalLock" />
<!--最多生成(MaxSizeRollBackups的值+1)个文件。如果注释掉,那么只生成一个文件。到了轮训条件,会从最早的开始覆盖以前的信息-->
<!-- 好像只有按Size分隔文件,才有效果 -->
<param name="MaxSizeRollBackups" value="31"/>
<!--如果RollingStyle为Size,这里需要填写正数加上单位(KB,MB)-->
<param name="MaximumFileSize" value="-1"/>
<!--轮询方式,文件大小,超过MaximumFileSize的值,则重新生成一个文件-->
<!--<param name="RollingStyle" value="Size"/>-->
<!--轮询方式,日期,每天生成一个文件。非当天的文件,会在File的值后面加上20151215-->
<param name="RollingStyle" value="Date"/>
<param name="StaticLogFileName" value="false"/>
<param name="datePattern" value="'zsyylog'yyyyMMdd'.txt'" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%m%n"/>
</layout>
</appender>
