从代码而不是从配置启用log4net的文件日志记录
以下测试失败的原因是什么？ （它在xunit中）我尝试过不同的appender并且它从不写任何东西虽然日志似乎已经准备好了。 我最终创建了自己的appender来测试它。
public class TestAppender : AppenderSkeleton { public event Action AppendCalled = delegate { }; protected override void Append(LoggingEvent loggingEvent) { AppendCalled(loggingEvent); } } public class Class1 { private TestAppender _appender = new TestAppender(); public Class1() { log4net.Util.LogLog.InternalDebugging = true; Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository(); Logger rootLogger = hierarchy.Root; rootLogger.Level = Level.All; Logger coreLogger = hierarchy.GetLogger("abc") as Logger; coreLogger.Level = Level.All; coreLogger.Parent = rootLogger; PatternLayout patternLayout = new PatternLayout(); patternLayout.ConversionPattern = "%logger - %message %newline"; patternLayout.ActivateOptions(); _appender.Layout = patternLayout; _appender.ActivateOptions(); coreLogger.AddAppender(_appender); } [Fact] public void Test() { bool called = false; _appender.AppendCalled += e => called = true; var log = LogManager.GetLogger("abc"); log.Debug("This is a debugging message"); Thread.Sleep(TimeSpan.FromSeconds(2)); log.Info("This is an info message"); Thread.Sleep(TimeSpan.FromSeconds(2)); log.Warn("This is a warning message"); Thread.Sleep(TimeSpan.FromSeconds(2)); log.Error("This is an error message"); Assert.True(called); } } 我总是使用下面的代码从代码中配置log4net。 效果很好！
Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository(); hierarchy.Root.RemoveAllAppenders(); /*Remove any other appenders*/ FileAppender fileAppender = new FileAppender(); fileAppender.AppendToFile = true; fileAppender.LockingModel = new FileAppender.MinimalLock(); fileAppender.File = Server.MapPath("/") + "log.txt"; PatternLayout pl = new PatternLayout(); pl.ConversionPattern = "%d [%2%t] %-5p [%-10c] %m%n%n"; pl.ActivateOptions(); fileAppender.Layout = pl; fileAppender.ActivateOptions(); log4net.Config.BasicConfigurator.Configure(fileAppender); //Test logger ILog log =LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); log.Debug("Testing!");
只是猜测那里……
您是否在程序集中定义了XmlConfiguration？
你在测试项目中忘记了吗？
[assembly: log4net.Config.XmlConfigurator(Watch = true)]
这通常会偶尔给我带来麻烦。
仍然不能说为什么上面的代码不起作用但我得到log4net正确配置并使用我的appender替换所有配置代码：
log4net.Config.BasicConfigurator.Configure(_appender);
从这里开始 。
