Log4Net使用指南之用log4net记录日志到数据库(含有自定义属性)------附Demo例子源代码

Log4NET简介

     log4net库是Apache log4j框架在Microsoft .NET平台的实现,是一个帮助程序员将日志信息输出到各种目标(控制台、文件、数据库等)的工具。

前提

   最近做项目需要记录系统日志和用户操作日志,就想起来了log4net,但是业务需要需要加入自定义属性,并把自定义属性日志数据插入到数据库中,看好趁这个机会学习总结下。

详细步骤

    一、首先下载:log4net.dll  下载地址:http://logging.apache.org/log4net/download_log4net.cgi

    二、在项目中进行引用。这个不多说了,相信大家都很熟悉这个过程。

    三、在web.config,加入以下代码:         

1  <configSections>
2     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" />
3   </configSections>

     四、然后在与web.config同目录下面新建个配置文件,我这建了个log4net.config,如下图

      

    五、在log4net.config加入以下代码,里面注释和详细 ,大家可以看如下代码:

      

  1 <?xml version="1.0" encoding="utf-8"?>
  2 <configuration>
  3   <configSections>
  4     <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net"/>
  5   </configSections>
  6 
  7   <log4net>
  8     <logger name="myLogger">
  9       <level value="INFO"/>
 10       <appender-ref ref="AdoNetAppender_SqlServer"/>

 12       <appender-ref ref="AdoNetAppender_SqlServer1"/>
 13       <!--sql server数据库2-->
 14       <appender-ref ref="AdoNetAppender_Sqllite"/>
 15       <!--sqlite数据库-->
 16       <appender-ref ref="InfoAppender"/>
 17       <!--记录到文件-->
 18     </logger>

282

284     <compilation debug="true" targetFramework="4.0" />
285   </system.web>
286 
287 </configuration>

       我主要说下里面自定义属性的代码的分别代表意义:

 <parameter>
 96         <parameterName value = "@UserName"/>
 97         <dbType value = "String"/>
 98         <size value = "50"/>
 99         <layout type = "Log4netExpand.MyLayout,log4nettest">
100           <conversionPattern value = "%property{UserName}"/>
101         </layout>
102       </parameter>

           其中MyLayout,是我们自己定义的类,下面有介绍;Log4netExpand是这个类的命名空间;log4nettest这个代表是aspx页面的命名空间。注意在此区分。

      六、自定义类,这些类呢包含将要插入数据库中的自定义字段

             命名空间为 Log4netExpand包含3个类:LogContent.cs、 MyLayout.cs 、MyMessagePatternConverter .cs

        1)第一个LogContent类如下:

            

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;

namespace Log4netExpand
{
    /// <summary>
    /// 包含了所有的自定字段属性
    /// </summary>
    public class LogContent
    {
        /// <summary>
        /// 时间类型 均为3
        /// </summary>
        public int Event_Type { get; set; }

        /// <summary>
        /// 日志分类描述,自定义
        /// </summary>
        public string EventCategory { get; set; }


        /// <summary>
        /// 日志分类号
        /// </summary>
        public int Event_ID { get; set; }

        /// <summary>
        /// 计算机IP
        /// </summary>
        public string ComputerName { get; set; }

        /// <summary>
        /// 计算机Mac 地址
        /// </summary>
        public string Mac_Address { get; set; }

        /// <summary>
        /// 系统登陆用户
        /// </summary>
        public string UserName { get; set; }

        /// <summary>
        /// Rier
        /// </summary>
        public string SourceType { get; set; }

        /// <summary>
        /// Rier Recorder audit
        /// </summary>
        public string Source { get; set; }

        /// <summary>
        /// 日志描述信息
        /// </summary>
        public string Description { get; set; }

    }
}

 

     2)第二个类MyLayout代码如下:

       

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Web;
 5 using log4net.Layout;
 6 
 7 namespace Log4netExpand
 8 {
 9     class MyLayout : PatternLayout
10     {
11         public MyLayout()
12         {
13             this.AddConverter("property", typeof(MyMessagePatternConverter));
14         }
15     }
16 }

      3)第三个类MyMessagePatternConverter 代码如下:

        

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Web;
 5 using System.Reflection;
 6 using log4net.Layout.Pattern;
 7 
 8 namespace Log4netExpand
 9 {
10     public class MyMessagePatternConverter : PatternLayoutConverter
11     {
12 
13         protected override void Convert(System.IO.TextWriter writer, log4net.Core.LoggingEvent loggingEvent)
14         {
15 
16             if (Option != null)
17             {
18 
19                 // Write the value for the specified key
20 
21                 WriteObject(writer, loggingEvent.Repository, LookupProperty(Option, loggingEvent));
22 
23             }
24 
25             else
26             {
27 
28                 // Write all the key value pairs
29 
30                 WriteDictionary(writer, loggingEvent.Repository, loggingEvent.GetProperties());
31 
32             }
33 
34             //if (Option != null)
35
