log4net简单用法

一、NuGet在Server,mvc中添加Common.Logging和common.Logging.Log4Net如下图

二、在Server层创建logger类

<?xml version="1.0" encoding="utf-8" ?>
<log4net>
  <!--级别层级ALL<DEBUG<INFO<WARN<ERROR<FATAL<OFF -->
  <!--调试日志-->
  <appender name="debugLog" type="log4net.Appender.RollingFileAppender,log4net" >
    <param name="File" value="logs\debug\debug.log" />
    <param name="AppendToFile" value="true" />
    <param name="RollingStyle" value="Date" />
    <param name="DatePattern" value="yyyyMMdd" />
    <param name="StaticLogFileName" value="true" />
    <layout type="log4net.Layout.PatternLayout,log4net">
      <param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss}%newline%message%n" />
    </layout>
    <filter type="log4net.Filter.LevelRangeFilter">
      <param name="LevelMin" value="DEBUG" />
      <param name="LevelMax" value="DEBUG" />
    </filter>
  </appender>

  <!--信息日志-->

    <param name="File" value="logs\info\info.log" />
    <param name="AppendToFile" value="true" />
    <param name="RollingStyle" value="Date" />
    <param name="DatePattern" value="yyyyMMdd" />
    <param name="StaticLogFileName" value="true" />
    <layout type="log4net.Layout.PatternLayout,log4net">
      <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" />
    </layout>
    <filter type="log4net.Filter.LevelRangeFilter">
      <param name="LevelMin" value="INFO" />
      <param name="LevelMax" value="INFO" />
    </filter>
  </appender>

  <!--错误日志-->
  <appender name="errorLog" type="log4net.Appender.RollingFileAppender,log4net" >
    <param name="File" value="logs\error\error.log" />
    <param name="AppendToFile" value="true" />

      <param name="LevelMin" value="ERROR" />
      <param name="LevelMax" value="ERROR" />
    </filter>
  </appender>
  <!--警告日志-->

  </appender>
  <!--致命错误日志-->

三、在mvc项目中添加log4net.config

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.IO;
using System.Reflection;
using System.Text;

namespace LogServer

}

四、在web.config的<configSections>内部添加

 <sectionGroup name="common">
      <section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
    </sectionGroup>

五、在web.config的</configSections>的后面添加

<common>
    <logging>
      <factoryAdapter type="Common.Logging.Log4Net.Log4NetLoggerFactoryAdapter, Common.Logging.Log4net">
        <arg key="configType" value="FILE-WATCH" />
        <!-- FILE,FILE-WATCH,INLINE,EXTERNAL-->
        <arg key="configFile" value="~/log4net.config" />
        <arg key="level" value="ALL" />
      </factoryAdapter>
    </logging>
  </common>

六、创建测试类Class1进行调用所有类结构如下图
