.Net Log4Net配置多文件日志记录

其他配置详情在网上都可以找到,但是很多看着都晕,本人就记录一下如何使用:

  1、按不同级别(官方说明)可记录的日志级别有:

    Info、Warn、Error、Debug

  2、可以按着四个配置四个输出日志路径和配置文件的配置节点

  可以在filter节点中配置value来区别记录日志的级别

  例如:

 

<appender name="Errorlog" type="log4net.Appender.RollingFileAppender">
      <!--定义文件存放位置-->
      <file value="Errorlog\\"/>
      <appendToFile value="true"/>
      <rollingStyle value="Date"/>
      <datePattern value="yyyyMMdd'.txt'"/>
      <staticLogFileName value="false"/>
      <param name="MaxSizeRollBackups" value="100"/>
      <layout type="log4net.Layout.PatternLayout">
        <!--每条日志末尾的文字说明
        输出格式
        样例:2008-03-26 13:42:32,111 [10] INFO  Log4NetDemo.MainClass [(null)] - info
        <conversionPattern value="%newline %n记录时间:%date %n线程ID:[%thread] %n日志级别:  %-5level %n出错类:%logger property: [%property{NDC}] - %n错误描述:%message%newline %n"/>-->
        <conversionPattern value="%date 描述:%message%n"/>
      </layout>
      <filter type="log4net.Filter.LevelRangeFilter">
        <param name="LevelMin" value="ERROR"/>
        <param name="LevelMax" value="ERROR"/>
      </filter>
    </appender>

 

然后可以根据自己需要配置不同的输出路径,注意filter里的param节点的value必须大写并只能是四种节点的一种value

最终可以在logger节点中配置指向appender

<logger name="myLogger">
<level value="ALL"/>
<appender-ref ref="Errorlog"/>
<appender-ref ref="Runlog"/>
<appender-ref ref="Warnlog"/>
<appender-ref ref="Debuglog"/>
<!--<appender-ref ref="ErrorLoging" />-->
</logger>

最后附上配置文件以及LogHelper类:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
  </configSections>
  <log4net>
    <!--定义输出到文件中-->
    <appender name="Errorlog" type="log4net.Appender.RollingFileAppender">
      <!--定义文件存放位置-->
      <file value="Errorlog\\"/>
      <appendToFile value="true"/>
      <rollingStyle value="Date"/>
      <datePattern value="yyyyMMdd'.txt'"/>
      <staticLogFileName value="false"/>
      <param name="MaxSizeRollBackups" value="100"/>
      <layout type="log4net.Layout.PatternLayout">
        <!--每条日志末尾的文字说明
        输出格式
        样例:2008-03-26 13:42:32,111 [10] INFO  Log4NetDemo.MainClass [(null)] - info
        <conversionPattern value="%newline %n记录时间:%date %n线程ID:[%thread] %n日志级别:  %-5level %n出错类:%logger property: [%property{NDC}] - %n错误描述:%message%newline %n"/>-->
        <conversionPattern value="%date 描述:%message%n"/>
      </layout>
      <filter type="log4net.Filter.LevelRangeFilter">
        <param name="LevelMin" value="ERROR"/>
        <param name="LevelMax" value="ERROR"/>
      </filter>
    </appender>
    <appender name="Runlog" type="log4net.Appender.RollingFileAppender">
      <!--定义文件存放位置-->
      <file value="Runlog\\"/>
      <appendToFile value="true"/>

      <staticLogFileName value="false"/>
      <param name="MaxSizeRollBackups" value="100"/>
