log4net按照不同的级别输出到不同文件

 

配置目标：

1）一个文件记录全部级别的日志；

2）记录某一级别的日志（使用LevelRangeFilter进行级别的过滤）。

 

Eg：

<log4net>

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

    <layout
type="log4net.Layout.PatternLayout">

      <conversionPattern
value="%d [%t] %-5p %l - %m%n %property{ServiceType}"/>

    </layout>

  </appender>

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

    <layout
type="log4net.Layout.PatternLayout">

      <conversionPattern
value="%d [%t] %-5p %l - %m%n"/>

    </layout>

  </appender>

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

    <param
name="File"
value="Log/alllLog.txt"/>

    <appendToFile

<rollingStyle

    <datePattern

    <maxSizeRollBackups

    <maximumFileSize

    <layout

    </layout>

    <filter

      <param

      <param

    </filter>

  </appender>

 
  <root>
