ASP.NET Core使用Log4net實現日志記錄功能
一、安裝Log4net
1、使用Nuget包進行安裝
在依賴項上面右鍵,選擇“管理NuGet程序包”,如下圖所示:
在瀏覽界面輸入log4net,然後點擊安裝,如下圖所示:
2、使用程序包管理器控制臺進行安裝
使用Install-Package Log4net命令進行安裝,如下圖所示:
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錄 <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類裡面配置使用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、在控制器裡面註入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("測試日志"); 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 }); } } }
