效果图:
1:第一步创建SQL表结构
CREATE TABLE [dbo].[LogDetails] (
[LogID] int NOT NULL IDENTITY(1,1) ,
[LogDate] datetime NOT NULL ,
[LogThread] nvarchar(100) NOT NULL ,
[LogLevel] nvarchar(200) NOT NULL ,
[LogLogger] nvarchar(500) NOT NULL ,
[LogMessage] nvarchar(3000) NOT NULL ,
[LogActionClick] nvarchar(4000) NULL ,
[UserName] nvarchar(30) NULL ,
[UserIP] varchar(20) NULL
)
2:创建项目然后下载log4net.dll 在项目中添加引用
http://logging.apache.org/log4net/download_log4net.cgi
下载Binaries 下面的
3:创建 log4net.config
<?xml version="1.0" encoding="utf-8" ?>
<log4net debug="false">
<!-- name属性指定其名称,type则是log4net.Appender命名空间的一个类的名称,意思是,指定使用哪种介质-->
<appender name="ADONetAppender" type="log4net.Appender.ADONetAppender">
<!--日志缓存写入条数 设置为0时只要有一条就立刻写到数据库-->
<bufferSize value="0" />
<!--日志数据库连接串-->

<!--日志数据库脚本-->
<commandText value="INSERT INTO LogDetails ([LogDate],[LogThread],[LogLevel],[LogLogger],[LogActionClick],[LogMessage],[UserName],[UserIP]) VALUES (@log_date, @thread, @log_level, @logger, @ActionsClick, @message,@UserName,@UserIP)" />
<!--日志时间LogDate -->
<parameter>

</layout>
</parameter>
<parameter>
<parameterName value="@ActionsClick" />
<dbType value="String" />
<size value="4000" />
<layout type="Log4NetApply.MyLayout" >
<conversionPattern value = "%property{ActionsClick}"/>
</layout>
</parameter>
<!--自定义UserName -->
<parameter>
<parameterName value="@UserName" />
<dbType value="String" />
<size value="30" />
<layout type="Log4NetApply.MyLayout" >
<!--log4net.MDC.Set("UserName", "asdfasdf");
<conversionPattern value = "%X{UserName}"/>-->
<conversionPattern value = "%property{UserName}"/>
</layout>
</parameter>
<parameter>
<parameterName value="@UserIP" />
<dbType value="String" />
<size value="20" />
<layout type="Log4NetApply.MyLayout" >
<conversionPattern value = "%property{UserIP}"/>
</layout>
</parameter>
</appender>
<!-- setup the root category, add the appenders and set the default level -->
<root>
<level value="Warn"/><!-- 定义记录的日志级别-->
<level value="Info"/>
<level value="Debug"/>
<level value="Fine"/>
<appender-ref ref="ADONetAppender" /><!-- 记录到什么介质中-->
</root>
<!-- specify the level for some specific categories -->
<!--//关于上边root到logger这块,如果同时出现,有可能会出现重复插入记录的情况:-->
<!--<logger name="iNotes">
<level value="WARN"/>
<level value="INFO"/>
<level value="DEBUG"/>
<level value="FINE"/>
<appender-ref ref="ADONetAppender"/>
</logger>
<logger name="StellaLogger">
<level value="ALL"/>
<appender-ref ref="AdoNetAppender" />
</logger>-->
<appender name="ReflectionLayout" type="log4net.Appender.RollingFileAppender,log4net">
<!--日志文件路径,按文件大小方式输出时在这里指定文件名,并且前面的日志按天在文件名后自动添加当天日期形成文件-->
<param name="File" value="D:/Log/" />
<!--是否追加到文件-->

</layout>
</appender>
</log4net>
4:在Web.config 里面加
configSections 节点 (CS可直接写在app.config里面,或者都写在一个config里面)
<configuration>
<strong> <span style="color:#FF0000;"> <configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
<log4net configSource="log4net.config"/></span></strong>
<system.web>
<compilation debug="true" targetFramework="4.5" />
<httpRuntime targetFramework="4.5" />
</system.web>
</configuration>
5:Properties 属性下面的AssemblyInfo.cs 追加
必须有这个,否则写入不到数据库中
//[assembly: log4net.Config.XmlConfigurator(Watch = true)]
//注意: ConfigFile 可以指定相对路径 和 绝对路径。 eg: /log/xxxx.log 或者 d://log//xxxx.log
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", ConfigFileExtension = "config", Watch = true)]
6:添加 Global.asax
然后在Application_Start 追加 读取配置程序文件
protected void Application_Start(object sender, EventArgs e)
{
//应用程序启动时,自动加载配置log4Net
XmlConfigurator.Configure();
}
7:创建自定义类 LogPublicClass.cs,为了方便写入数据库中 自定义的一些信息
using log4net.Layout;
using log4net.Layout.Pattern;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Reflection;
using System.Web;
namespace Log4NetApply
{
/// <summary>
/// 包含了所有的自定字段属性
/// </summary>
public class LogContent
{
public LogContent(string macAddress, string computerName, string actionsclick, string description)
{
UserIP = macAddress;
UserName = computerName;
ActionsClick = actionsclick;
Message = description;
}
/// <summary>
/// 访问IP
/// </summary>
public string UserIP { get; set; }
/// <summary>
/// 系统登陆用户
/// </summary>
public string UserName { get; set; }
/// <summary>
/// 动作事件
/// </summary>
public string ActionsClick { get; set; }
/// <summary>
/// 日志描述信息
/// </summary>
public string Message { get; set; }
}
public class MyLayout : PatternLayout
{
public MyLayout()
{
this.AddConverter("property", typeof(LogInfoPatternConverter));
}
}
public class LogInfoPatternConverter : PatternLayoutConverter
{
protected override void Convert(System.IO.TextWriter writer, log4net.Core.LoggingEvent loggingEvent)
{
if (Option != null)
{
// Write the value for the specified key
WriteObject(writer, loggingEvent.Repository, LookupProperty(Option, loggingEvent));
}
else
{
// Write all the key value pairs
WriteDictionary(writer, loggingEvent.Repository, loggingEvent.GetProperties());
}
}
/// <summary>
/// 通过反射获取传入的日志对象的某个属性的值
/// </summary>
/// <param name="property"></param>
/// <returns></returns>
private object LookupProperty(string property, log4net.Core.LoggingEvent loggingEvent)
{
object propertyValue = string.Empty;
PropertyInfo propertyInfo = loggingEvent.MessageObject.GetType().GetProperty(property);
if (propertyInfo != null)
propertyValue = propertyInfo.GetValue(loggingEvent.MessageObject, null);
return propertyValue;
}
}
}
8:示例使用
try
{
log.Info(new LogContent("127.0.0.1", "111111", "登陆系统", "登陆成功"));
var ss = 1 - int.Parse("sss");
}
catch(Exception ex)
{
log.Error(new LogContent("127.0.0.1", "111111", "登陆系统", ex.Message+":"+ex.StackTrace));
}
