log4net日志分割，按大小分割

最近写了一个socket通信的手表在线服务端，在日志方面，记录下Log4net日志分割

1.引入log4net.dll

2.web.config添加configsection handler 映射：

<configuration>

    <configSections>

      <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />

    </configSections>

</configuration>

3.建立 log4net.config 文件,此文件在logs文件夹下面按日期生成

<?xml version="1.0" encoding="utf-8"?>

<log4net>

  <!-- OFF, FATAL, ERROR, WARN, INFO, DEBUG, ALL -->

  <!-- Set root logger level to ERROR and its appenders -->

  <root>

    <level value="ALL"/>

    <appender-ref ref="SysAppender"/>

  </root>

  <!-- Print only messages of level DEBUG or above in the packages -->

  <logger name="WebLogger">

    <level value="DEBUG"/>

  </logger>

  <appender name="SysAppender" type="log4net.Appender.RollingFileAppender,log4net" >

    <param name="File" value="Logs/" />

    <param name="AppendToFile" value="true" />

    <param name="RollingStyle" value="Date" />

    <param name="DatePattern" value="&quot;Logs_&quot;yyyyMMdd&quot;.txt&quot;" />

    <param name="StaticLogFileName" value="false" />

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

      <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />

      <param name="Header" value="
----------------------header--------------------------
" />

      <param name="Footer" value="
----------------------footer--------------------------
" />

    </layout>

  </appender>

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

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

      <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />

    </layout>

  </appender>

</log4net>

4.按大小分割的映射文件

<?xml version="1.0" encoding="utf-8"?>

<log4net>

  <!-- OFF, FATAL, ERROR, WARN, INFO, DEBUG, ALL -->

  <!-- Set root logger level to ERROR and its appenders -->

  <root>

    <level value="ALL"/>

    <appender-ref ref="SysAppender"/>

  </root>

  <!-- Print only messages of level DEBUG or above in the packages -->

  <logger name="WebLogger">

    <level value="DEBUG"/>

  </logger>

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

    <param name="File" value="Logs\Logs.txt"/>

    <param name="AppendToFile" value="true"/>

    <param name="MaxSizeRollBackups" value="12"/> <!-- 切割最多文件数 -->

    <param name="MaximumFileSize" value="500KB"/> <!-- 每个文件的大小 -->

    <param name="RollingStyle" value="Size"/>

    <param name="StaticLogFileName" value="true"/>

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

      <param name="ConversionPattern" value="%d [%t] %-5p %c [%x] - %m%n"/>

    </layout>

  </appender>

</log4net>

我的注解：

配置文件是用反射和名称生成对应的类的声明，　RollingFileAppender  SysAppender 对象，下面是这个类的各个参数。这个类一般是这样设计的
