.net core2.0 中使用log4net Web程序

标签:max value   errorlog   val   version   readonly   logfile   解析   orm   ram   

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>();

        /// 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 */

        public static void Debug(object source, string message, params object[] ps)

            if (logger.IsDebugEnabled)
            {
                logger.Debug(message);
            }
        }
