Log4net重复日志记录 [英] Log4net duplicate logging entires

问题描述

我最近把log4net日志从配置文件切换到以编程方式设置。这导致不合适的条目重复2次或有时3次。这是代码。它使用一个看起来像这样的字符串logger1 | debug，logger2 | info

  private void SetupLog4netLoggers（）
 {
 IAppender appender = GetAppender（）; 
 
 SetupRootLogger（appender）; 
 
 foreach（记录器中的字符串记录器）
 {
 CommaStringList parts = new CommaStringList（logger，'|'）; 
 if（parts.Count！= 2）
 continue; 
 
 AddLogger（parts [0]，parts [1]，appender）; 
} 
 
 log.Debug（Log4net已设置）; 
} 
 
 private IAppender GetAppender（）
 {
 RollingFileAppender appender = new RollingFileAppender（）; 
 appender.File = LogFile; 
 appender.AppendToFile = true; 
 appender.MaximumFileSize = MaximumFileSize; 
 appender.MaxSizeRollBackups = MaximumBackups; 
 
 PatternLayout layout = new PatternLayout（PATTERN）; 
 layout.ActivateOptions（）; 
 
 appender.Layout = layout; 
 appender.ActivateOptions（）; 
 
 return appender; 
} 
 
 private void SetupRootLogger（IAppender appender）
 {
层次结构=（层次结构）LogManager.GetRepository（）; 
 
 hierarchy.Root.RemoveAllAppenders（）; 
 hierarchy.Root.AddAppender（appender）; 
 hierarchy.Root.Level = GetLevel（RootLevel）; 
 
 hierarchy.Configured = true; 
 
 log.Debug（root logger setup，level [+ RootLevel +]）; 
} 
 
 private void AddLogger（string name，string level，IAppender appender）
 {
 Logger logger = LogManager.GetRepository（）。GetLogger（name）as Logger ; 
 if（logger == null）
 return; 
 
 logger.Level = GetLevel（level）; 
 logger.Additivity = false; 
 logger.RemoveAllAppenders（）; 
 logger.AddAppender（appender）; 
 
 log.Debug（logger [+ name +] added，level [+ level +]）; 
} 
  

这是我们在日志中看到的一个例子...

 2010-05-06 15：50：39,796 [1] DEBUG NHibernate.AdoNet.AbstractBatcher  - 运行BatcherImpl.Dispose（true）
  

欢迎任何提示。

解决方案

p>我认为答案是 - 它实际上不是重复的。没有调试NHibernate代码我不能确定，但​​我猜它可能只是写出来或反复做同样的事情。



我们要回到使用配置文件无论如何，将不得不看到我是否仍然可以重复。

I recently switched out log4net logging from using config files to being set up programmatically. This has resulted in the nhiberate entries getting repeated 2 or sometimes 3 times. Here's the code. It uses a string which looks something like this "logger1|debug,logger2|info"

    private void SetupLog4netLoggers()
    {
        IAppender appender = GetAppender();

        SetupRootLogger(appender);

        foreach (string logger in Loggers)
        {
            CommaStringList parts = new CommaStringList(logger, '|');
            if (parts.Count != 2)
                continue;

            AddLogger(parts[0], parts[1], appender);
        }

        log.Debug("Log4net has been setup");
    }

    private IAppender GetAppender()
    {
        RollingFileAppender appender = new RollingFileAppender();
        appender.File = LogFile;
        appender.AppendToFile = true;
        appender.MaximumFileSize = MaximumFileSize;
        appender.MaxSizeRollBackups = MaximumBackups;

        PatternLayout layout = new PatternLayout(PATTERN);
        layout.ActivateOptions();

        appender.Layout = layout;
        appender.ActivateOptions();

        return appender;
    }

    private void SetupRootLogger(IAppender appender)
    {
        Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository();

        hierarchy.Root.RemoveAllAppenders();
        hierarchy.Root.AddAppender(appender);
        hierarchy.Root.Level = GetLevel(RootLevel);

        hierarchy.Configured = true;

        log.Debug("Root logger setup, level[" + RootLevel + "]");
    }

    private void AddLogger(string name, string level, IAppender appender)
    {
        Logger logger = LogManager.GetRepository().GetLogger(name)as Logger;
        if (logger == null)
            return;

        logger.Level = GetLevel(level);
        logger.Additivity = false;
        logger.RemoveAllAppenders();
        logger.AddAppender(appender);

        log.Debug("logger[" + name + "] added, level[" + level + "]");
    }

And here's an example of what we see in our logs...

2010-05-06 15:50:39,781 [1] DEBUG NHibernate.Impl.SessionImpl - running ISession.Dispose()
2010-05-06 15:50:39,781 [1] DEBUG NHibernate.Impl.SessionImpl - closing session
2010-05-06 15:50:39,781 [1] DEBUG NHibernate.AdoNet.AbstractBatcher - running BatcherImpl.Dispose(true)
2010-05-06 15:50:39,796 [1] DEBUG NHibernate.Impl.SessionImpl - running ISession.Dispose()
2010-05-06 15:50:39,796 [1] DEBUG NHibernate.Impl.SessionImpl - closing session
2010-05-06 15:50:39,796 [1] DEBUG NHibernate.AdoNet.AbstractBatcher - running BatcherImpl.Dispose(true)

2010-05-06 15:50:39,796 [1] DEBUG NHibernate.AdoNet.AbstractBatcher - running BatcherImpl.Dispose(true)

Any hints welcome.

解决方案

I think the answer is - its not in fact writing duplicates. Without debugging the NHibernate code I can't be sure but I'm guessing its probably just writing it out or doing same thing repeatedly

We're going back to using config files anyway so will have to see if I still get possible duplicates.
