log4net将消息记录到所有附加程序（/所有文件）中

Question

我在log4net如何管理附加程序以及这些附加程序的消息方面遇到问题。

当我将1条消息记录到1个记录器（对应于1个附加程序）时，该消息仍然以所有日志文件结尾（因此，该消息似乎将传递给所有附加程序）

我在做什么错？！

我设法在单元测试中重现我的问题：

    [Test]
    public void Test()
    {
        var hierarchy = (Hierarchy)LogManager.GetRepository();

        var patternLayout = new PatternLayout
        {
            ConversionPattern = "%date %level %logger - %message%newline" //CreateLayoutPattern(appenderConfiguration.Layout),
        };
        patternLayout.ActivateOptions();

        hierarchy.Configured = true;
        for (var i = 1; i < 10; i++)
        {
            var logFile = Path.Combine(_testLogFolder, $"SomeLog_Test{i}.csv");

            var roller = new RollingFileAppender
            {
                Name = $"Test{i}",
                AppendToFile = true,
                File = logFile,
                CountDirection = 1,
                Layout = patternLayout,
                ImmediateFlush = true,
                // MaxSizeRollBackups is set to max int, software will have an independent mechanism in place (reaper) to clean up old files
                MaxSizeRollBackups = int.MaxValue,
                MaximumFileSize = "1MB",
                RollingStyle = RollingFileAppender.RollingMode.Size,
                StaticLogFileName = false,
                PreserveLogFileNameExtension = true,
                Threshold = Level.All
            };

            roller.ActivateOptions();
            hierarchy.Root.AddAppender(roller);
        }

        // A
        LogManager.GetLogger("Test1").Info("Whatever");

        // Now the ALL of the log files contain the message "Whatever", why?!?! I only logged to 'Test1'
    }

Answer 1

显然，这是默认行为（当我考虑更长的时间时才有意义：））。

我需要的是可以实现的。不必将所有附加程序添加到hierarchy.Root.AddAppender，我必须为每个附加程序名称创建记录器，然后将滚子添加到该记录器。例如：

var logger = hierarchy.GetLogger("Test1", hierarchy.LoggerFactory);

logger.AddAppender(roller);
logger.Level = Level.All;
logger.Additivity = false;

并删除：

hierarchy.Root.AddAppender(roller);
