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="LogInfo" />  
      <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="LogError" />  
      <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="LogDebug" />  
      <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
