ASP.NET Core 2.0使用Log4net实现记录日志功能

一、安装Log4net

1、使用Nuget包进行安装

在依赖项上面右键，选择“管理NuGet程序包”，如下图所示：

在浏览界面输入log4net，然后点击安装，如下图所示：

2、使用程序包管理器控制台进行安装

使用Install-Package Log4net命令进行安装，如下图所示：

二、配置log4net使用的配置文件

配置文件如下：

 <?xml version="1.0" encoding="utf-8" ?>

  <configuration>

    <!-- This section contains the log4net configuration settings -->

    <log4net>

      <appender name="ConsoleAppender" type="log4net.Appender.ConsoleAppender">

        <layout type="log4net.Layout.PatternLayout" value="%date [%thread] %-5level %logger - %message%newline" />

      </appender>

      <appender name="FileAppender" type="log4net.Appender.FileAppender">

      <file value="log-file.log" />

      <appendToFile value="true" />

      <layout type="log4net.Layout.PatternLayout">

        <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />

      </layout>

    </appender>

    <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender">

      <file value="D:\study\logfile/" />   //指定日志文件保存的目录

      <appendToFile value="true" />

      <rollingStyle value="Composite" />

      <staticLogFileName value="false" />

      <datePattern value="yyyyMMdd'.log'" />

      <maxSizeRollBackups value="10" />

      <maximumFileSize value="1MB" />

      <layout type="log4net.Layout.PatternLayout">

        <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message%newline" />

      </layout>

    </appender>

    <!-- Setup the root category, add the appenders and set the default level -->

    <root>

      <level value="ALL" />

      <appender-ref ref="ConsoleAppender" />

      <appender-ref ref="FileAppender" />

        <appender-ref ref="RollingLogFileAppender" />

      </root>

    </log4net>

  </configuration>

三、在Startup.cs类里面配置使用log4net

 public static ILoggerRepository repository { get; set; }

 public Startup(IConfiguration configuration)

 {

             Configuration = configuration;

             repository = LogManager.CreateRepository("NETCoreRepository");

             // 指定配置文件

             XmlConfigurator.Configure(repository, new FileInfo("log4net.config"));

 }

四、在控制器里面注入log4net

 using System;

 using System.Collections.Generic;

 using System.Diagnostics;

 using System.Linq;

 using System.Threading.Tasks;

 using log4net;

 using Microsoft.AspNetCore.Hosting;

 using Microsoft.AspNetCore.Mvc;

 using NetCoreLogDemo.Models;

 namespace NetCoreLogDemo.Controllers

 {

     public class HomeController : Controller

     {

         private ILog log;

         public HomeController(IHostingEnvironment hostingEnv)

         {

             this.log = LogManager.GetLogger(Startup.repository.Name, typeof(HomeController));

         }

         public IActionResult Index()

         {

             log.Error("测试日志");

             return View();

         }

         public IActionResult About()

         {

             ViewData["Message"] = "Your application description page.";

             return View();

         }

         public IActionResult Contact()

         {

             ViewData["Message"] = "Your contact page.";

             return View();

         }

         public IActionResult Error()

         {

             return View(new ErrorViewModel { RequestId = Activity.Current?.Id ?? HttpContext.TraceIdentifier });

         }

     }

 }

测试结果：
