一、Log4Net官網apache
二、Web使用:app
Web.Config 添加: ui
<configSections> <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> </configSections> <log4net debug="false"> <root> <level value="Error" /> <appender-ref ref="UserInfoLogger" /> </root> <logger name="UserInfoLogger"> <!--日誌的等級,它們由高到底分別爲: OFF > FATAL > ERROR > WARN > INFO > DEBUG > ALL 注意:日誌記錄時只記錄當前及更高等級日誌。LevelRangeFilter節點存在時以節點爲配置爲準--> <level value="DEBUG" /> <!--Appender(輸出流)名稱--> <appender-ref ref="UserInfoLogger" /> </logger> <appender name="UserInfoLogger" type="log4net.Appender.RollingFileAppender,log4net"> <!--日誌文件目錄--> <param name="File" value="UserInfoLogger/" /> <!--寫入方式爲追加--> <param name="AppendToFile" value="true" /> <!--日誌回滾方式爲日期--> <param name="RollingStyle" value="Date" /> <Encoding value="UTF-8" /> <!--日誌文件命名方式--> <param name="DatePattern" value=""Logs_"yyyyMMddHH".txt"" /> <!--日誌名稱--> <param name="StaticLogFileName" value="false" /> <!--最多記錄日誌文件數--> <param name="MaxSizeRollBackups" value="10" /> <maxSizeRollBackups value="10" /> <maximumFileSize value="5MB" /> <lockingModel type="log4net.Appender.FileAppender+MinimalLock" /> <layout type="log4net.Layout.PatternLayout,log4net"> <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" /> </layout> <!--日誌級別限制--> <filter type="log4net.Filter.LevelRangeFilter"> <param name="LevelMin" value="DEBUG" /> <param name="LevelMax" value="WARN" /> </filter> </appender> </log4net>
Global.asax 添加spa
log4net.Config.XmlConfigurator.Configure();.net
三、添加類庫debug
public class Log4NetHelper { private static log4net.ILog log = log4net.LogManager.GetLogger("UserInfoLogger"); public static void WriteLogDebug(string message) { //啓用Debug if (log.IsDebugEnabled) { log.Debug($"{DateTime.Now}:Debug:{message}"); } if (log.IsErrorEnabled) { log.Error($"{DateTime.Now}:Error:{message}"); } if (log.IsFatalEnabled) { log.Fatal($"{DateTime.Now}:Fatal:{message}"); } if (log.IsInfoEnabled) { log.Info($"{DateTime.Now}:Info:{message}"); } } }
