第一步: NuGet管理安装log4net组件。
第二步:添加log4net.config配置文件
<?xml version="1.0" encoding="utf-8" ?> <log4net> <root> <level value="DEBUG"/> <appender-ref ref="SysAppender"/> <appender-ref ref="consoleApp"/> </root> <!--信息日志配置--> <appender name="SysAppender" type="log4net.Appender.RollingFileAppender"> <param name="File" value="D:\\Logs\\" /> <param name="AppendToFile" value="true" /> <param name="MaximumFileSize" value="20MB" /> <param name="MaxSizeRollBackups" value="100" /> <param name="StaticLogFileName" value="false" /> <param name="DatePattern" value="\\yyyyMM\\yyyyMMdd".log"" /> <param name="RollingStyle" value="Composite" /> <layout type="log4net.Layout.PatternLayout"> <param name="ConversionPattern" value="%n -------------------------------------------------------------------------------------- %n日志时间:%d [%t] %n日志级别:%-5p %n日 志 类:%c [%x] %n%m %n" /> <param name="Header" value=" ====================================================================================== " /> </layout> </appender> <appender name="consoleApp" type="log4net.Appender.ConsoleAppender,log4net"> <layout type="log4net.Layout.PatternLayout,log4net"> <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n" /> </layout> </appender> <logger name="WebLogger"> <level value="DEBUG"/> </logger> </log4net>
第三步:定义一个配置,添加一个类UseLog4netApplicationBuilder.cs
public static class UseLog4netApplicationBuilder { /// <summary> /// 使用log4net配置 /// </summary> /// <param name="app"></param> /// <returns></returns> public static IApplicationBuilder UseLog4net(this IApplicationBuilder app) { var logRepository = log4net.LogManager.CreateRepository(System.Reflection.Assembly.GetEntryAssembly(), typeof(log4net.Repository.Hierarchy.Hierarchy)); log4net.Config.XmlConfigurator.Configure(logRepository, new FileInfo("log4net.config")); return app; } }
第四步: Startup.cs添加Configure
public void Configure(IApplicationBuilder app, IWebHostEnvironment env) { if (env.IsDevelopment()) { app.UseDeveloperExceptionPage(); } app.UseLog4net(); //这里是添加的 app.UseHttpsRedirection(); app.UseRouting(); app.UseAuthorization(); app.UseEndpoints(endpoints => { endpoints.MapControllers(); }); }
第六步: Controller里面使用
public class WeatherForecastController : ControllerBase { private static readonly string[] Summaries = new[] { "Freezing", "Bracing", "Chilly", "Cool", "Mild", "Warm", "Balmy", "Hot", "Sweltering", "Scorching" }; private readonly ILog log; public WeatherForecastController(ILogger<WeatherForecastController> logger) { this.log = LogManager.GetLogger(typeof(WeatherForecastController)) ; } [HttpGet] public IEnumerable<WeatherForecast> Get() { log.Error("Error 90000: Error Error Error Error Error Error Error Error!"); log.Info("Info 10000: Info Info Info Info Info Info Info Info Info Info Info Info Info Info!"); log.Warn("Warn 20000: Warn Warn Warn Warn Warn Warn Warn Warn Warn Warn Warn Warn Warn Warn!"); var rng = new Random(); return Enumerable.Range(1, 5).Select(index => new WeatherForecast { Date = DateTime.Now.AddDays(index), TemperatureC = rng.Next(-20, 55), Summary = Summaries[rng.Next(Summaries.Length)] }) .ToArray(); } }
第七步: 查看日志, 找到你定义的路径,打开log文件
