技術分享-Log4net日誌配置

準備：log4net.dll

1，新建web項目，引入dll，然後修改AssemblyInfo.cs文件天下如下一行

[assembly: log4net.Config.XmlConfigurator( Watch = true)] 

可以添加參數：

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)] 


代表日誌的配置參數寫在一個單獨的配置文件中：ConfigFile = "log4net.config"

2，在相應的地方配置參數；加了ConfigFile = "log4net.config"則在根目錄下新建一個log4net.config文件，然後配置在該文件下面

，如果沒有配置，則參數配置在webconfig中。

a,首先聲明節點

webconfig:

  <configSections>
    <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net-net-1.0" />
  </configSections>

b,然後配置參數，如果聲明瞭ConfigFile = "log4net.config"  則直接在log4net.config中配置

<log4net>

    <logger name="logerror">
      <level value="ERROR" />
      <appender-ref ref="ErrorAppender" />
    </logger>
    <logger name="loginfo">
      <level value="INFO" />
      <appender-ref ref="InfoAppender" />
    </logger>
    <appender name="ErrorAppender" type="log4net.Appender.RollingFileAppender">
      <param name="File" value="D:\\ErrorLog.log" />
      <param name="AppendToFile" value="true" />
      <param name="MaxSizeRollBackups" value="100" />
      <param name="MaximumFileSize" value="1MB" /> 
		<param name="RollingStyle" value="Size" />
      <param name="StaticLogFileName" value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%-5p %d [%c] %m%n" />
      </layout>
    </appender>
    <appender name="InfoAppender" type="log4net.Appender.RollingFileAppender">
      <param name="File" value="D:\\InfoLog.log" />
      <param name="AppendToFile" value="true" />
      <param name="MaxSizeRollBackups" value="100" />
      <param name="MaximumFileSize" value="1MB" />
      <param name="RollingStyle" value="Size" />
      <param name="StaticLogFileName" value="true" />
      <layout type="log4net.Layout.PatternLayout">
        <param name="ConversionPattern" value="%-5p %d [%c] %m%n" />
      </layout>
    </appender>

  </log4net>

3，直接聲明調用即可

//log4net日誌專用
        public static readonly log4net.ILog loginfo = log4net.LogManager.GetLogger("loginfo");
        public static readonly log4net.ILog logerror = log4net.LogManager.GetLogger("logerror");
