.net core2.0 中使用log4net
2024-08-31 04:03:55
一、nuget安装log4net
二、添加log4net.config配置文件
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<!--添加自定义节点：log4net type：解析类名，程序集名(log4net.dll)-->
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net"/>
</configSections>
<log4net>
<root>
<!--<level value="DEBUG"/>-->
<!--控制级别，由低到高: ALL|DEBUG|INFO|WARN|ERROR|FATAL|OFF ALL表示允许所有的日志请求。OFF是拒绝所有的请求。-->
<!--比如定义级别为INFO，则INFO级别向下的级别，比如DEBUG日志将不会被记录-->
<level value="ALL"/>
<!--根据log级别记录到不同的日志文件-->
<appender-ref ref="ErrorLog" />
</root>
<!--Error-->
<appender name="ErrorLog" type="log4net.Appender.RollingFileAppender">
<file value="Log/"/>
<appendToFile value="true" />
<rollingStyle value="Date" />
<!--日期的格式，每天换一个文件记录，如不设置则永远只记录一天的日志，需设置-->
<DatePattern value="yyyyMMdd"_Error.log"" />
<!--日志文件名是否为静态-->
<StaticLogFileName value="false"/>
<!--多线程时采用最小锁定-->
<lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
<!--布局（向用户显示最后经过格式化的输出信息）-->
<layout type="log4net.Layout.PatternLayout">
<ConversionPattern value="%date 线程ID:[%thread] 日志级别：%-5level 出错类：%logger property:[%property{NDC}] - 错误描述：%message %newline" />
</layout>
<securityContext type="log4net.Util.WindowsSecurityContext">
<credentials value="Process" />
</securityContext>
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="DEBUG" />
<levelMax value="ERROR" />
</filter>
</appender>
<!--Error-->
</log4net>
</configuration>
三、编写loghelper
using GrabNovelApi;
using log4net;
using System;
using System.Collections.Concurrent;
using System.Collections.Generic;
using System.Text; namespace Grab.api
{
public static class LogHelper
{
private static readonly ConcurrentDictionary<Type, ILog> Loggers = new ConcurrentDictionary<Type, ILog>(); /// <summary>
/// 获取记录器
/// </summary>
/// <param name="source">soruce</param>
/// <returns></returns>
private static ILog GetLogger(Type source)
{
if (Loggers.ContainsKey(source))
{
return Loggers[source];
}
else
{
ILog logger = LogManager.GetLogger(Startup.repository.Name,source);
Loggers.TryAdd(source, logger);
return logger;
}
} /* Log a message object */ /// <summary>
/// 调试信息
/// </summary>

public static void Debug(object source, string message, params object[] ps)
{
Debug(source.GetType(), string.Format(message, ps));
} /// <summary>

/// <param name="source">source</param>
/// <param name="message">message</param>
public static void Debug(Type source, string message)
{
ILog logger = GetLogger(source);
if (logger.IsDebugEnabled)
{
logger.Debug(message);
}
} /// <summary>

public static void Info(Type source, object message)
{
ILog logger = GetLogger(source);
if (logger.IsInfoEnabled)
{
logger.Info(message);
}

public static void Error(Type source, object message)
{

{
logger.Error(message);
}
} /// <summary>
