网站并发要求,网站程序设计,自己做微信团购小程序,上海小企业网站建设和之前的ASP.NET MVC中的使用LOG4NET的方法有些不同#xff0c;这里先记录一下#xff0c;使用步骤如下 #xff1a; 1. 建立 ASP.NET CORE项目中#xff0c;NUGET中搜索log4net后下载安装 2. 根目录建立 log4net.config文件#xff0c;内容如下#xff1a; ?xml ve… 和之前的ASP.NET MVC中的使用LOG4NET的方法有些不同这里先记录一下使用步骤如下 1. 建立 ASP.NET CORE项目中NUGET中搜索log4net后下载安装 2. 根目录建立 log4net.config文件内容如下 ?xml version1.0 encodingutf-8 ? configuration   !-- This section contains the log4net configuration settings --   log4net     appender nameConsoleAppender typelog4net.Appender.ConsoleAppender       layout typelog4net.Layout.PatternLayout value%date [%thread] %-5level %logger - %message%newline /     /appender     !--appender nameFileAppender typelog4net.Appender.FileAppender       file valuelog-file.log /       appendToFile valuetrue /       layout typelog4net.Layout.PatternLayout         conversionPattern value%date [%thread] %-5level %logger [%property{NDC}] - %message%newline /       /layout     /appender--     appender nameRollingLogFileAppender typelog4net.Appender.RollingFileAppender       file valuelogfile/ /       appendToFile valuetrue /       rollingStyle valueComposite /       staticLogFileName valuefalse /       datePattern valueyyyyMMdd.log /       maxSizeRollBackups value10 /       maximumFileSize value1MB /       layout typelog4net.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 valueALL /       appender-ref refConsoleAppender /       appender-ref refFileAppender /       appender-ref refRollingLogFileAppender /     /root   /log4net /configuration 3. Startup.cs文件中的Startup方法和ConfigureServices方法里的AddMvc代码改下核心代码如下记得引用相应的命名空间         //log4net日志         public static ILoggerRepository repository { get; set; }         public Startup(IConfiguration configuration)         {             Configuration configuration;             //加载log4net日志配置文件             repository LogManager.CreateRepository(NETCoreRepository);             XmlConfigurator.Configure(repository, new FileInfo(log4net.config));         }         public IConfiguration Configuration { get; }         // This method gets called by the runtime. Use this method to add services to the container.         public void ConfigureServices(IServiceCollection services)         {             services.AddMvc(options             {                 options.Filters.AddModels.HttpGlobalExceptionFilter(); //加入全局异常类             });         } 4. Models文件夹中建立 HttpGlobalExceptionFilter.cs 类用于全局异常后记录到日志中内容代码如下 using log4net; using Microsoft.AspNetCore.Mvc.Filters; using System; using System.Collections.Generic; using System.Linq; using System.Threading.Tasks; namespace WebApplication1.Models {     /// summary     /// 全局异常类     /// /summary     public class HttpGlobalExceptionFilter : IExceptionFilter     {         private ILog log LogManager.GetLogger(Startup.repository.Name, typeof(HttpGlobalExceptionFilter));         public void OnException(ExceptionContext context)         {             log.Error(context.Exception);         }     } } 5. 下面是控制器的代码有异常会自动记录下来用那个log也能手工记录日志信息 using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using System.Threading.Tasks; using log4net; using Microsoft.AspNetCore.Mvc; using WebApplication1.Models; namespace WebApplication1.Controllers {     public class HomeController : Controller     {         private ILog log LogManager.GetLogger(Startup.repository.Name, typeof(HttpGlobalExceptionFilter));         public IActionResult Index()         {             throw new Exception(牛腩自定义异常);  //有异常则会记录到logfile文件夹中             return View();         }         public IActionResult About()         {             ViewData[Message] Your application description page.;             log.Info(打开about页面了); //普通的记录日志             return View();         }       } } 转载于:https://www.cnblogs.com/niunan/p/8437350.html
