在api层内容根目录添加 config 文件

Blog.Core
├─ Controllers
│  └─ WeatherForecastController.cs
├─ Log4net.config // 就是这里
├─ Program.cs
├─ Properties
│  └─ launchSettings.json
├─ Startup.cs
├─ appsettings.Development.json
└─ appsettings.json

config 的内容是：

<?xml version="1.0" encoding="utf-8"?>
<log4net>
    <!-- 将日志以回滚文件的形式写到文件中 -->
    <!-- 按日期切分日志文件，并将日期作为日志文件的名字 -->
    <appender name="RollingFileAppenderNameByDate" type="log4net.Appender.RollingFileAppender">
      <!-- 日志文件存放位置，可以为绝对路径也可以为相对路径 -->
      <file value="Log/" />
      <!-- 将日志信息追加到已有的日志文件中-->
      <appendToFile value="true" />
      <!-- 最小锁定模式，以允许多个进程可以写入同一个文件 -->
      <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
      <!-- 指定按日期切分日志文件 -->
      <rollingStyle value="Date" />
      <!-- 日志文件的命名规则 -->
      <datePattern value="&quot;GlobalExcepLogs_&quot;yyyyMMdd&quot;.log&quot;" />
      <!-- 当将日期作为日志文件的名字时，必须将staticLogFileName的值设置为false -->
      <staticLogFileName value="false" />

      <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date| %newline%message%newline--------------------------------%newline" />        
        <!-- 这里也可以直接用json格式输出，具体请自行百度 -->
      </layout>
    </appender>

    <root>
      <!-- 控制级别，由低到高：ALL|DEBUG|INFO|WARN|ERROR|FATAL|OFF -->
      <!-- 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 -->
      <!-- 如果没有定义LEVEL的值，则缺省为DEBUG -->
      <level value="ALL" />
      <!-- 按日期切分日志文件，并将日期作为日志文件的名字 -->
      <appender-ref ref="RollingFileAppenderNameByDate" />
    </root>
  </log4net>

引用 nuget 包

  <ItemGroup>
    <PackageReference Include="Microsoft.Extensions.Logging.Log4Net.AspNetCore" Version="3.0.3" />
  </ItemGroup>

Program.cs 创建服务


 XmlDocument log4netConfig = new XmlDocument();
 log4netConfig.Load(File.OpenRead("Log4net.config"));//注意名字

 var repo = log4net.LogManager.CreateRepository(
     Assembly.GetEntryAssembly(), typeof(log4net.Repository.Hierarchy.Hierarchy));

 log4net.Config.XmlConfigurator.Configure(repo, log4netConfig["log4net"]);

配置中间件，接管 ILogger

 public void Configure(IApplicationBuilder app, IWebHostEnvironment env, ILoggerFactory loggerFactory)
 {
     if (env.IsDevelopment())
     {
         app.UseDeveloperExceptionPage();
     }
     
     // 就是这里
     loggerFactory.AddProvider(new Log4NetProvider("Log4net.config"));

     app.UseRouting();

     app.UseAuthorization();

     app.UseEndpoints(endpoints =>
     {
         endpoints.MapControllers();
     });
 }

控制器注入

 private readonly ILogger<WeatherForecastController> _logger;

 public WeatherForecastController(ILogger<WeatherForecastController> logger)
 {
     _logger = logger;
 }

 [HttpGet]
 public IEnumerable<WeatherForecast> Get()
 {
     _logger.LogError("this is an error.");
     var rng = new Random();
     return null;
 }
