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

 1 [assembly: log4net.Config.XmlConfigurator(Watch = true)]
 2 namespace Zy.Utility.Core
 3 {
 4     /// <summary>
 5     /// 日志处理类
 6     /// </summary>
 7     public static class Log
 8     {
 9         public static void Error(string msg)
10         {
11             log4net.ILog log = log4net.LogManager.GetLogger(msg);
12             log.Error(msg);
13         }
14
15         public static void Info(string msg)
16         {
17             log4net.ILog log = log4net.LogManager.GetLogger(msg);
18             log.Info(msg);
19         }
20
21         public static void Warning(string msg)
22         {
23             log4net.ILog log = log4net.LogManager.GetLogger(msg);
24             log.Warn(msg);
25         }
26
27         public static void Error(string msg, Exception ex)
28         {
29             log4net.ILog log = log4net.LogManager.GetLogger(msg);
30             log.Error("Error", ex);
31         }
32
33         public static void Info(string msg, Exception ex)
34         {
35             log4net.ILog log = log4net.LogManager.GetLogger(msg);
36             log.Info("Info", ex);
37         }
38
39         public static void Warning(string msg, Exception ex)
40         {
41             log4net.ILog log = log4net.LogManager.GetLogger(msg);
42             log.Warn("Warning", ex);
43         }
44     }
45 }  

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

 1 <log4net>
 2     <!--数据日志-->
 3     <appender name="InfoRollingFileAppender" type="log4net.Appender.RollingFileAppender">
 4       <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
 5       <param name="File" value="Log\Info\" />
 6       <param name="AppendToFile" value="true" />
 7       <param name="rollingStyle" value="Date" />
 8       <param name="datePattern" value="yyyy-MM-dd.‘Info.log‘" />
 9       <param name="staticLogFileName" value="false" />
10       <layout type="log4net.Layout.PatternLayout">
11         <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" />
12       </layout>
13       <filter type="log4net.Filter.LevelRangeFilter">
14         <param name="LevelMin" value="INFO" />
15         <param name="LevelMax" value="INFO" />
16       </filter>
17     </appender>
18     <!--错误日志-->
19     <appender name="ErrorRollingFileAppender" type="log4net.Appender.RollingFileAppender">
20       <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
21       <param name="File" value="Log\Error\" />
22       <param name="AppendToFile" value="true" />
23       <param name="rollingStyle" value="Date" />
24       <param name="datePattern" value="yyyy-MM-dd.‘error.log‘" />
25       <param name="staticLogFileName" value="false" />
26       <layout type="log4net.Layout.PatternLayout">
27         <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" />
28       </layout>
29       <filter type="log4net.Filter.LevelRangeFilter">
30         <param name="LevelMin" value="ERROR" />
31         <param name="LevelMax" value="ERROR" />
32       </filter>
33     </appender>
34     <!--调试日志-->
35     <appender name="DebugRollingFileAppender" type="log4net.Appender.RollingFileAppender">
36       <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
37       <param name="File" value="Log\Debug\" />
38       <param name="AppendToFile" value="true" />
39       <param name="rollingStyle" value="Date" />
40       <param name="datePattern" value="yyyy-MM-dd.‘debug.log‘" />
41       <param name="staticLogFileName" value="false" />
42       <layout type="log4net.Layout.PatternLayout">
43         <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" />
44       </layout>
45       <filter type="log4net.Filter.LevelRangeFilter">
46         <param name="LevelMin" value="DEBUG" />
47         <param name="LevelMax" value="DEBUG" />
48       </filter>
49     </appender>
50     <root>
51       <level value="DEBUG" />
52       <!--文件形式记录日志-->
53       <appender-ref ref="ErrorRollingFileAppender" />
54       <appender-ref ref="DebugRollingFileAppender" />
55       <appender-ref ref="InfoRollingFileAppender" />
56     </root>
57   </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
