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

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 36 //{ 37 38 // // Write the value for the specified key 39 40 // WriteObject(writer, loggingEvent.Repository, loggingEvent.LookupProperty(Option)); 41 42 //} 43 44 //else 45 46 //{ 47 48 // // Write all the key value pairs 49 50 // WriteDictionary(writer, loggingEvent.Repository, loggingEvent.GetProperties()); 51 52 //} 53 54 } 55 56 57 58 /// <summary> 59 60 /// 通过反射获取传入的日志对象的某个属性的值 61 62 /// </summary> 63 64 /// <param name="property"></param> 65 66 /// <returns></returns> 67 68 private object LookupProperty(string property, log4net.Core.LoggingEvent loggingEvent) 69 { 70 71 object propertyValue = string.Empty; 72 73 74 75 PropertyInfo propertyInfo = loggingEvent.MessageObject.GetType().GetProperty(property); 76 77 if (propertyInfo != null) 78 79 propertyValue = propertyInfo.GetValue(loggingEvent.MessageObject, null); 80 81 82 83 return propertyValue; 84 85 } 86 87 } 88 }
七、代码页,实现通过log4net把日志(含自定一生属性)添加到数据库
1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Web; 5 using System.Web.UI; 6 using System.Web.UI.WebControls; 7 8 using System.Management; 9 using Log4netExpand; 10 11 namespace Log4netExpand 12 { 13 public partial class test : System.Web.UI.Page 14 { 15 protected void Page_Load(object sender, EventArgs e) 16 { 17 18 } 19 protected void Button1_Click(object sender, EventArgs e) 20 { 21 log4net.ILog log = log4net.LogManager.GetLogger("myLogger"); 22 23 LogContent logmodel = new LogContent(); 24 logmodel.Event_Type = 3; 25 logmodel.EventCategory = "登陆系统"; 26 logmodel.Event_ID = 1; 27 logmodel.ComputerName = Request.UserHostAddress; 28 logmodel.Mac_Address = GetMacAddress(); 29 logmodel.Source = "SS"; 30 logmodel.SourceType = "1"; 31 logmodel.UserName = "ADMIN"; 32 logmodel.Description = "TEST";//在记录数据库操作时,可以在petapoco底层将sql语句放入其中。 33 LogHelper.WriteLog(logmodel); 34 35 lbMsg.Text = "数据记录成功!"; 36 } 37 38 public string GetMacAddress() 39 { 40 string mac = ""; 41 try 42 { 43 //获取网卡硬件地址 44 ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration"); 45 ManagementObjectCollection moc = mc.GetInstances(); 46 47 List<string> list = new List<string>(); 48 49 foreach (ManagementObject mo in moc) 50 { 51 if ((bool)mo["IPEnabled"] == true) 52 { 53 mac = mo["MacAddress"].ToString(); 54 55 list.Add(mac); 56 } 57 } 58 moc = null; 59 mc = null; 60 61 mac = list[list.Count - 1]; 62 63 return mac; 64 } 65 catch 66 { 67 return "unknow"; 68 } 69 } 70 } 71 }
