log4net配置
mysql数据库，创建这个表
DROP TABLE IF EXISTS `t_errorlog`;
CREATE TABLE `t_errorlog` (
`rowid` int(11) NOT NULL AUTO_INCREMENT,
`log_date` datetime DEFAULT NULL COMMENT ‘log时间‘,
`Thread` varchar(255) DEFAULT NULL COMMENT ‘线程‘,
`Level` varchar(100) DEFAULT NULL COMMENT ‘级别‘,
`logger` varchar(510) DEFAULT NULL COMMENT ‘名称空间‘,
`message` longtext COMMENT ‘出現錯誤讯息‘,
`method` varchar(50) DEFAULT NULL COMMENT ‘出错的方法‘,
PRIMARY KEY (`rowid`)
) ENGINE=InnoDB AUTO_INCREMENT=1403 DEFAULT CHARSET=utf8;
1.第一步：把log4net加入到引用
2.第二步：配置web.config 可以配置成数据库或者文件或者操作系统事件里面
<configSections>
<section name="log4net" type="System.Configuration.IgnoreSectionHandler"/>
</configSections>
<log4net>
<appender name="ADONetAppender_SqlServer" type="log4net.Appender.AdoNetAppender">
<bufferSize value="http://www.mamicode.com/1"/>
<connectionType value="http://www.mamicode.com/MySql.Data.MySqlClient.MySqlConnection, MySql.Data"/>
<connectionString value="http://www.mamicode.com/Server=192.168.19.10;database=user;user=gigade;pwd=ge20110831;charset=‘utf8‘" />
<commandText value="http://www.mamicode.com/insert into t_errorlog (`log_date`,`thread`,`level`,`logger`,`message`,`method`) values (@log_date, @thread, @log_level, @logger, @content,@method)"/>
<parameter>
<parameterName value="http://www.mamicode.com/@log_date"/>
<dbType value="http://www.mamicode.com/DateTime"/>
<layout type="log4net.Layout.RawTimeStampLayout"/>
</parameter>
<parameter>
<parameterName value="http://www.mamicode.com/@thread"/>
<dbType value="http://www.mamicode.com/String"/>
<size value="http://www.mamicode.com/255"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="http://www.mamicode.com/%thread"/>
</layout>
</parameter>
<parameter>
<parameterName value="http://www.mamicode.com/@log_level"/>
<dbType value="http://www.mamicode.com/String"/>
<size value="http://www.mamicode.com/50"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="http://www.mamicode.com/%level"/>
</layout>
</parameter>
<parameter>
<parameterName value="http://www.mamicode.com/@logger"/>
<dbType value="http://www.mamicode.com/String"/>
<size value="http://www.mamicode.com/255"/>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="http://www.mamicode.com/%logger"/>
</layout>
</parameter>
<parameter>
<parameterName value="http://www.mamicode.com/@content"/>
<dbType value="http://www.mamicode.com/String"/>
<size value="http://www.mamicode.com/4000"/>
<layout type="Admin.gigade.Log4NetCustom.CustomLayout">
<conversionPattern value="http://www.mamicode.com/%property{Content}"/>
</layout>
</parameter>
<parameter>
<parameterName value="http://www.mamicode.com/@method"/>
<dbType value="http://www.mamicode.com/String"/>
<size value="http://www.mamicode.com/50"/>
<layout type="Admin.gigade.Log4NetCustom.CustomLayout">
<conversionPattern value="http://www.mamicode.com/%property{MethodName}"/>
</layout>
</parameter>
</appender>
<root>
<level value="http://www.mamicode.com/ALL"/>
<appender-ref ref="ADONetAppender_SqlServer"/>
</root>
</log4net>
3.第三步：
如果是网站：
MVC中在global.asax里面新增配置
void Application_Start(object sender, EventArgs e)
{
// 在应用程序启动时运行的代码
log4net.Config.XmlConfigurator.Configure();
}
如果是web项目和winform项目或者控制台项目：
要在AssemblyInfo.cs 新增
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)] //当把东西写到web.config中时,改为web.config ----可以
或者：[assembly: log4net.Config.XmlConfigurator()] （把log4net的配置配置在web的配置文件时）
4.第四步:
try
{
string a = "1a2b3c";
int abc = Convert.ToInt32(a);
}
catch (Exception ex)
{
Admin.gigade.Log4NetCustom.LogMessage logMessage = new Admin.gigade.Log4NetCustom.LogMessage();
logMessage.Content = string.Format("TargetSite:{0},Source:{1},Message:{2}", ex.TargetSite.Name, ex.Source, ex.Message);
logMessage.MethodName = System.Reflection.MethodBase.GetCurrentMethod().Name;
log.Error(logMessage);
}
5.第五步
Log4NetCustom文件夹
CustomLayout.cs 类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using log4net.Util;
using System.IO;
using log4net.Layout.Pattern;
using System.Collections;
using log4net.Core;
namespace Admin.gigade.Log4NetCustom
{
public class CustomLayout : log4net.Layout.PatternLayout
{
public CustomLayout()
{
this.AddConverter("property", typeof(MyMessagePatternConverter));
}
}
}
LogMessage.cs 类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace Admin.gigade.Log4NetCustom
{
public class LogMessage
{
private string m_MethodName;
private string m_Content;
public LogMessage()
{
}
public LogMessage(string methodName, string content)
{
m_MethodName = methodName;
m_Content = content;
}
public string MethodName
{
get
{
return m_MethodName;
}
set
{
m_MethodName = value;
}
}
public string Content
{
get
{
return m_Content;
}
set
{
m_Content = value;
}
}
}
}
MyMessagePatternConverter.cs 类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using log4net.Layout.Pattern;
using System.IO;
using log4net.Core;
namespace Admin.gigade.Log4NetCustom
{
public class MyMessagePatternConverter : 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());
}
//if (Option != null)
//{
// // Write the value for the specified key
// WriteObject(writer, loggingEvent.Repository, loggingEvent.LookupProperty(Option));
//}
//else
//{
// // Write all the key value pairs
// WriteDictionary(writer, loggingEvent.Repository, loggingEvent.GetProperties());
//}
}
/// <summary>
/// 通q过反I射g获取Lu传入J的o日e志屠对象H的o某Y个属性E的o值E
/// </summary>
/// <param name="property"></param>
/// <returns></returns>
private object LookupProperty(string property, log4net.Core.LoggingEvent loggingEvent)
{
object propertyValue = http://www.mamicode.com/string.Empty;
System.Reflection.PropertyInfo propertyInfo = loggingEvent.MessageObject.GetType().GetProperty(property);
if (propertyInfo != null)
propertyValue = http://www.mamicode.com/propertyInfo.GetValue(loggingEvent.MessageObject, null);
return propertyValue;
}
}
}
OK了.
