log4net 控制台和文件和数据库输出三种方式

SDKB英文 06-24 08:30 阅读 4

1、新建console应用项目SendEvaluateDataToProvinceConsole

2、选择SendEvaluateDataToProvinceConsole项目右键 选择 管理NuGet程序包,搜索log4net ,点击安装

3、选择SendEvaluateDataToProvinceConsole项目右键 新建App.config,App.config添加一下内容

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<!-- log4net的定义配置节 -->
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
<log4net>
<!--日志保存到文件里面Log.txt-->
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="Log\Log.txt"/>
<param name="AppendToFile" value="true"/>
<param name="MaxSizeRollBackups" value="100"/>
<param name="MaximumFileSize" value="2MB"/>
<param name="RollingStyle" value="Size"/>
<param name="StaticLogFileName" value="true"/>
<!--<param name="Encoding" value="utf-8" />-->
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%-5p %d [%c] %m%n"/>
</layout>
</appender>
<!--日志输出到Console-->
<appender name="ColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
<mapping>
<level value="ERROR"/>
<foreColor value="White"/>
<backColor value="Red,HighIntensity"/>
</mapping>
<mapping>
<level value="DEBUG"/>
<backColor value="Green"/>
</mapping>
<mapping>
<level value="Info"/>
<backColor value="Yellow"/>
</mapping>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline"/>
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<param name="LevelMin" value="Debug"/>
<param name="LevelMax" value="Fatal"/>
</filter>
</appender>
<!--日志输出到数据库-->
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<!--数据表创建脚本-->
<!--CREATE TABLE LOG(Id integer primary KEY AUTOINCREMENT,Date datetime NOT NULL,UserId varchar(20) NOT NULL,UserName varchar(50) NOT NULL,Message varchar(4000) NOT NULL,Exception varchar(2000) NULL);-->
<!--日志缓存写入条数-->
<!--bufferSize表示批处理的日志事件,可以避免每次日志事件都访问数据库,原本是<bufferSize value="100" />一百条才插入-->
<bufferSize value="1"/>
<!--日志数据库连接串-->
<connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<connectionString value="DATABASE=EvMS;SERVER=192.168.1.234;UID=evms;PWD=123456;Connect Timeout=15;" />
<!--System.Data.SQLite, Version=1.0.65.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139-->
<!--<connectionType value="System.Data.SQLite.SQLiteConnection, System.Data, Version=1.0.65.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139"/>-->
<!--<connectionString value="Data source=F:\Person\Longteng\LongtengSln\SendEvaluateDataToProvinceConsole\Data\mysqlite.db;Connect Timeout=15"/>-->
<!--日志数据库脚本-->
<commandText value="INSERT INTO LOG([Date],[UserId],[UserName],[Message],[Exception]) VALUES (@Date,@UserId,@UserName,@Message,@Exception)"/>
<!--日志时间Date -->
<parameter>
<parameterName value="@Date"/>
<dbType value="DateTime"/>
<layout type="log4net.Layout.RawTimeStampLayout"/>
</parameter>
<!--自定义UserId -->
<parameter>
<parameterName value="@UserId"/>
<dbType value="String"/>
<size value="20"/>
<layout type="log4net.Layout.PatternLayout"/>
</parameter>
<!--自定义UserName -->
<parameter>
<parameterName value="@UserName"/>
<dbType value="String"/>
<size value="50"/>
<layout type="log4net.Layout.PatternLayout"/>
</parameter>
<!--日志信息Message -->
<parameter>
<parameterName value="@Message"/>
<dbType value="String"/>
<size value="4000"/>
<layout type="log4net.Layout.PatternLayout"/>
</parameter>
<!--异常信息Exception -->
<parameter>
<parameterName value="@Exception"/>
<dbType value="String"/>
<size value="2000"/>
<layout type="log4net.Layout.PatternLayout"/>
</parameter>
</appender>
<root>
<level value="all"/>
<appender-ref ref="RollingLogFileAppender"/>
<appender-ref ref="ColoredConsoleAppender"/>
<appender-ref ref="AdoNetAppender"/>
</root>
</log4net>
<startup>
<supportedRuntime version="v2.0.50727"/>
</startup>
</configuration>

4、Program.cs中添加代码

using log4net;
using System;
using System.Reflection;

namespace SendEvaluateDataToProvinceConsole
{
class Program
{
/// <summary>
/// 记录日志的日志对象
/// </summary>
public static ILog Log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
static void Main(string[] args)
{
//log4net.Config.XmlConfigurator.ConfigureAndWatch(new System.IO.FileInfo(@"F:\Person\Longteng\LongtengSln\SendEvaluateDataToProvince\App.config"));
log4net.Config.XmlConfigurator.Configure();//这一句很重要。。。。。
try
{
Log.Info("123...");
Log.Info("普通日志");
Log.Error("错误日志");
Log.Debug("异常信息");
Log.Fatal("致命错误");
Log.Warn("警告信息");

LogEntity logEntity = new LogEntity
{
//Id= "123",
UserId = "123",
UserName = "张三",
Message = "消息西夏熊",
Exception = "Exception"
};

Log.Debug(logEntity);
Console.Read();
}
catch (Exception e)
{
Console.WriteLine(e.Message);
Console.WriteLine(e.Source);
Console.WriteLine(e.StackTrace);
Console.WriteLine(e.InnerException != null ? e.InnerException.ToString() : "");
Console.ReadLine();
}
}
}
}

 

5、运行结果

log4net 控制台和文件和数据库输出三种方式_自定义

 

 

6、上图运行结果注意有些数据不太对,就是插入的是LogEntity 对象,显示的就是一个对象,而不是对象具体对应的数据

LogEntity logEntity = new LogEntity
{
//Id= "123",
UserId = "123",
UserName = "张三",
Message = "消息西夏熊",
Exception = "Exception"
};

分析原因是因为LogEntity 是自定义的对象,log4net并不知道LogEntity 是什么东西,所以我们转换一下,把LogEntity 转换成log4net认识的对象就可以了,其实就是修改显示的log4net模式PatternLayout,

代码如下:

先建MyPatternConverter类,继承log4net的PatternLayoutConverter类

using log4net.Core;
using log4net.Layout.Pattern;
using System.IO;
using System.Reflection;

namespace SendEvaluateDataToProvinceConsole
{
public class MyPatternConverter : PatternLayoutConverter
{
protected override void Convert(TextWriter writer, LoggingEvent loggingEvent)
{
if (Option != null)
WriteObject(writer, loggingEvent.Repository, LookupProperty(Option, loggingEvent));
else
WriteDictionary(writer, loggingEvent.Repository, loggingEvent.GetProperties());
}

//通过反射获取传入的日志对象的某个属性的值
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;
}
}
}

 

再新建MyLayout类,继承log4net的PatternLayout类

using log4net.Layout;

namespace SendEvaluateDataToProvinceConsole
{
public class MyLayout : PatternLayout
{
public MyLayout()
{
this.AddConverter("Property", typeof(MyPatternConverter));
}
}
}

上面建好MyPatternConverter类和MyLayout类以后,修改App.config配置文件如下

<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<!-- log4net的定义配置节 -->
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
<log4net>
<!--日志保存到文件里面Log.txt-->
<appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<param name="File" value="Log\Log.txt"/>
<param name="AppendToFile" value="true"/>
<param name="MaxSizeRollBackups" value="100"/>
<param name="MaximumFileSize" value="2MB"/>
<param name="RollingStyle" value="Size"/>
<param name="StaticLogFileName" value="true"/>
<!--<param name="Encoding" value="utf-8" />-->//注释掉,使用下面的自定义转换SendEvaluateDataToProvinceConsole.MyLayout,下面的同理
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%-5p %d [%c] %m%n"/>
</layout>
</appender>
<!--日志输出到Console-->
<appender name="ColoredConsoleAppender" type="log4net.Appender.ColoredConsoleAppender">
<mapping>
<level value="ERROR"/>
<foreColor value="White"/>
<backColor value="Red,HighIntensity"/>
</mapping>
<mapping>
<level value="DEBUG"/>
<backColor value="Green"/>
</mapping>
<mapping>
<level value="Info"/>
<backColor value="Yellow"/>
</mapping>
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline"/>
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<param name="LevelMin" value="Debug"/>
<param name="LevelMax" value="Fatal"/>
</filter>
</appender>
<!--日志输出到数据库-->
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<!--数据表创建脚本-->
<!--CREATE TABLE LOG(Id integer primary KEY AUTOINCREMENT,Date datetime NOT NULL,UserId varchar(20) NOT NULL,UserName varchar(50) NOT NULL,Message varchar(4000) NOT NULL,Exception varchar(2000) NULL);-->
<!--日志缓存写入条数-->

<size value="2000"/>
<!--<layout type="log4net.Layout.PatternLayout"/>-->
<!--<layout type="log4net.Layout.ExceptionLayout" />-->
<layout type="SendEvaluateDataToProvinceConsole.MyLayout">
<conversionPattern value="%Property{Exception}" />
</layout>
</parameter>
</appender>
<root>
<level value="all"/>
<appender-ref ref="RollingLogFileAppender"/>
<appender-ref ref="ColoredConsoleAppender"/>
<appender-ref ref="AdoNetAppender"/>
</root>
</log4net>
<startup>
<supportedRuntime version="v2.0.50727"/>
</startup>
</configuration>

 

 在运行的话数据库中的运行结果如下:
