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

三、在mvc项目中添加log4net.config

} } } }
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
