从零开始写C# MVC框架之--- 配置log4日志

在框架中配置日志分2步，一个是在帮助项目Zy.Utilities--Zy.Utility.Core中新建log类，封装写入日志方法，还需要在Zy.Utility.Core添加 log4net 的引用

1、log实现类

 [assembly: log4net.Config.XmlConfigurator(Watch = true)]
 namespace Zy.Utility.Core
 {
     /// <summary>
     /// 日志处理类
     /// </summary>
     public static class Log
     {
         public static void Error(string msg)
         {
             log4net.ILog log = log4net.LogManager.GetLogger(msg);
             log.Error(msg);
         }  

         public static void Info(string msg)
         {
             log4net.ILog log = log4net.LogManager.GetLogger(msg);
             log.Info(msg);
         }  

         public static void Warning(string msg)
         {
             log4net.ILog log = log4net.LogManager.GetLogger(msg);
             log.Warn(msg);
         }  

         public static void Error(string msg, Exception ex)
         {
             log4net.ILog log = log4net.LogManager.GetLogger(msg);
             log.Error("Error", ex);
         }  

         public static void Info(string msg, Exception ex)
         {
             log4net.ILog log = log4net.LogManager.GetLogger(msg);
             log.Info("Info", ex);
         }  

         public static void Warning(string msg, Exception ex)
         {
             log4net.ILog log = log4net.LogManager.GetLogger(msg);
             log.Warn("Warning", ex);
         }
     }
 }  

2、在Web项目的web.config中配置log4，配置完后，启动项目后会在ZyCommon-ZyWeb项目中生成一个Log的文件夹

 <log4net>
     <!--数据日志-->
     <appender name="InfoRollingFileAppender" type="log4net.Appender.RollingFileAppender">
       <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
       <param name="File" value="Log\Info\" />
       <param name="AppendToFile" value="true" />
       <param name="rollingStyle" value="Date" />
       <param name="datePattern" value="yyyy-MM-dd.'Info.log'" />
       <param name="staticLogFileName" value="false" />
       <layout type="log4net.Layout.PatternLayout">
         <conversionPattern value="%n%n%n 记录时间：%date %n日志级别：  %-5level %n出错类：%logger  %n错误描述：%message %newline%newline" />
       </layout>
       <filter type="log4net.Filter.LevelRangeFilter">
         <param name="LevelMin" value="INFO" />
         <param name="LevelMax" value="INFO" />
       </filter>
     </appender>
     <!--错误日志-->
     <appender name="ErrorRollingFileAppender" type="log4net.Appender.RollingFileAppender">
       <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
       <param name="File" value="Log\Error\" />
       <param name="AppendToFile" value="true" />
       <param name="rollingStyle" value="Date" />
       <param name="datePattern" value="yyyy-MM-dd.'error.log'" />
       <param name="staticLogFileName" value="false" />
       <layout type="log4net.Layout.PatternLayout">
         <conversionPattern value="%n%n%n 记录时间：%date %n日志级别：  %-5level %n出错类：%logger  %n错误描述：%message %newline%newline" />
       </layout>
       <filter type="log4net.Filter.LevelRangeFilter">
         <param name="LevelMin" value="ERROR" />
         <param name="LevelMax" value="ERROR" />
       </filter>
     </appender>
     <!--调试日志-->
     <appender name="DebugRollingFileAppender" type="log4net.Appender.RollingFileAppender">
       <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
       <param name="File" value="Log\Debug\" />
       <param name="AppendToFile" value="true" />
       <param name="rollingStyle" value="Date" />
       <param name="datePattern" value="yyyy-MM-dd.'debug.log'" />
       <param name="staticLogFileName" value="false" />
       <layout type="log4net.Layout.PatternLayout">
         <conversionPattern value="%n%n%n 记录时间：%date %n日志级别：  %-5level %n出错类：%logger  %n错误描述：%message %newline%newline" />
       </layout>
       <filter type="log4net.Filter.LevelRangeFilter">
         <param name="LevelMin" value="DEBUG" />
         <param name="LevelMax" value="DEBUG" />
       </filter>
     </appender>
     <root>
       <level value="DEBUG" />
       <!--文件形式记录日志-->
       <appender-ref ref="ErrorRollingFileAppender" />
       <appender-ref ref="DebugRollingFileAppender" />
       <appender-ref ref="InfoRollingFileAppender" />
     </root>
   </log4net>  

Log文件夹下分为Debug、Error、Info文件夹，分别写入错误级别不同的日志信息

开发中报错后，错误信息会写入Error文件夹中，按配置规则每天生成一个txt文件夹，调试时也可以写入日志中
