C# 利用log4net 把日誌寫入到資料庫
阿新 • • 發佈：2019-01-29
效果圖:
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 )
3：建立 log4net.config
<?xml version="1.0" encoding="utf-8" ?> <log4net debug="false"> <!-- name屬性指定其名稱,type則是log4net.Appender名稱空間的一個類的名稱,意思是,指定使用哪種介質--> <appender name="ADONetAppender" type="log4net.Appender.ADONetAppender"> <!--日誌快取寫入條數 設定為0時只要有一條就立刻寫到資料庫--> <bufferSize value="0" /> <!--日誌資料庫連線串--> <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" /> <connectionString value="DATABASE=GoodLook;SERVER=xx.xx.140.170;UID=sa;PWD=123456a;Connect Timeout=30;" /> <!--日誌資料庫指令碼--> <commandText value="INSERT INTO LogDetails ([LogDate],[LogThread],[LogLevel],[LogLogger],[LogActionClick],[LogMessage],[UserName],[UserIP]) VALUES (@log_date, @thread, @log_level, @logger, @ActionsClick, @message,@UserName,@UserIP)" /> <!--日誌時間LogDate --> <parameter> <parameterName value="@log_date" /> <dbType value="DateTime" /> <layout type="log4net.Layout.RawTimeStampLayout" /> </parameter> <!--執行緒號--> <parameter> <parameterName value="@thread" /> <dbType value="String" /> <size value="100" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%t" /> </layout> </parameter> <!--日誌型別LogLevel --> <parameter> <parameterName value="@log_level" /> <dbType value="String" /> <size value="200" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%p" /> </layout> </parameter> <!--日誌名稱--> <parameter> <parameterName value="@logger" /> <dbType value="String" /> <size value="500" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%logger" /> </layout> </parameter> <parameter> <parameterName value="@message" /> <dbType value="String" /> <size value="3000" /> <layout type="Log4NetApply.MyLayout"> <conversionPattern value="%property{Message}" /> </layout> </parameter> <parameter> <parameterName value="@ActionsClick" /> <dbType value="String" /> <size value="4000" /> <layout type="Log4NetApply.MyLayout" > <conversionPattern value = "%property{ActionsClick}"/> </layout> </parameter> <!--自定義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"/><!-- 定義記錄的日誌級別--> <level value="Info"/> <level value="Debug"/> <level value="Fine"/> <appender-ref ref="ADONetAppender" /><!-- 記錄到什麼介質中--> </root> <!-- specify the level for some specific categories --> <!--//關於上邊root到logger這塊，如果同時出現，有可能會出現重複插入記錄的情況：--> <!--<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"> <!--日誌檔案路徑,按檔案大小方式輸出時在這裡指定檔名，並且前面的日誌按天在檔名後自動添加當天日期形成檔案--> <param name="File" value="D:/Log/" /> <!--是否追加到檔案--> <param name="AppendToFile" value="true" /> <!--記錄日誌寫入檔案時，不鎖定文字檔案--> <!--<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />--> <!--Unicode編碼--> <!--<Encoding value="UTF-8" />--> <!--最多產生的日誌檔案數，value="－1"為不限檔案數--> <!--<param name="MaxSizeRollBackups" value="10" />--> <!--是否只寫到一個檔案中--> <param name="StaticLogFileName" value="false" /> <!--按照何種方式產生多個日誌檔案(日期[Date],檔案大小[Size],混合[Composite])--> <param name="RollingStyle" value="Composite" /> <!--按日期產生資料夾，檔名［在日期方式與混合方式下使用］--> <param name="DatePattern" value="yyyy-MM-dd/"ReflectionLayout.log"" /> <!--<param name="DatePattern" value="yyyyMMdd/yyyyMMdd"-TimerServer.log"" />--> <!--<param name="DatePattern" value="yyyyMMdd/"TimerServer/TimerServer.log"" />--> <!--每個檔案的大小。只在混合方式與檔案大小方式下使用，超出大小的在檔名後自動增加1重新命名--> <param name="maximumFileSize" value="500KB" /> <!--記錄的格式。--> <layout type="TGLog.ExpandLayout2.ReflectionLayout,TGLog"> <param name="ConversionPattern" value="記錄時間：%date 執行緒ID:[%thread] 日誌級別：%-5level 記錄類：%logger 操作者ID：%property{Operator} 操作型別：%property{Action}%n 當前機器名:%property%n當前機器名及登入使用者：%username %n 記錄位置：%location%n 訊息描述：%property{Message}%n 異常：%exception%n 訊息：%message%newline%n%n" /> </layout> </appender> </log4net>
4：在Web.config 裡面加 configSections 節點 (CS可直接寫在app.config裡面，或者都寫在一個config裡面)
<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 屬性下面的AssemblyInfo.cs 追加 必須有這個，否則寫入不到資料庫中
//[assembly: log4net.Config.XmlConfigurator(Watch = true)]
//注意： ConfigFile 可以指定相對路徑 和 絕對路徑。 eg: /log/xxxx.log 或者 d://log//xxxx.log
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", ConfigFileExtension = "config", Watch = true)]
6：新增 Global.asax
然後在Application_Start 追加 讀取配置程式檔案
protected void Application_Start(object sender, EventArgs e)
{
//應用程式啟動時，自動載入配置log4Net
XmlConfigurator.Configure();
}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>
/// 包含了所有的自定欄位屬性
/// </summary>
public class LogContent
{
public LogContent(string macAddress, string computerName, string actionsclick, string description)
{
UserIP = macAddress;
UserName = computerName;
ActionsClick = actionsclick;
Message = description;
}
/// <summary>
/// 訪問IP
/// </summary>
public string UserIP { get; set; }
/// <summary>
/// 系統登陸使用者

public string UserName { get; set; }
/// <summary>
/// 動作事件
/// </summary>
public string ActionsClick { get; set; }
/// <summary>
/// 日誌描述資訊
/// </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>
/// 通過反射獲取傳入的日誌物件的某個屬性的值
/// </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", "登陸系統", "登陸成功"));
var ss = 1 - int.Parse("sss");
}
catch(Exception ex)
{
log.Error(new LogContent("127.0.0.1", "111111", "登陸系統", ex.Message+":"+ex.StackTrace));
