Log4net设置了两个文件的日志记录，与c#代码的日志记录级别不同
本文关键字：记录 日志 代码 设置 两个 文件 Log4net | 更新日期: 2023-09-27 18:14:36
这是我的问题，我想通过c#应用程序和log4net登录2个不同的文件(一个用于错误，一个用于普通信息)，我在xml中找到了配置，但我想从代码中做到这一点，这是我为设置一个文件的日志发现的源:
public static void Setup()
{
Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository();
hierarchy.Root.RemoveAllAppenders();
PatternLayout patternLayout = new PatternLayout();
patternLayout.ConversionPattern = "%date THREAD [%thread] %logger: %message%newline"; //%-5level
patternLayout.ActivateOptions();
RollingFileAppender infoRoller = new RollingFileAppender();
infoRoller.AppendToFile = true;
infoRoller.File = @"logs'";
infoRoller.RollingStyle = RollingFileAppender.RollingMode.Date;
infoRoller.MaxSizeRollBackups = 3;
infoRoller.Layout = patternLayout;
infoRoller.DatePattern = @"IN'FO'_yyyy-MM-dd.'lo'g";
infoRoller.StaticLogFileName = false;
infoRoller.ActivateOptions();
hierarchy.Root.AddAppender(infoRoller);
MemoryAppender memory = new MemoryAppender();
memory.ActivateOptions();
hierarchy.Root.AddAppender(memory);
hierarchy.Root.Level = Level.Debug;
hierarchy.Configured = true;
}
在另一个类中用于日志记录:
private readonly ILog log = LogManager.GetLogger("GENERAL-LOG");
和
Logger.Setup();
log.Debug("Configurazioni caricate con successo.");
代码可以工作。
现在，我做了这个改变得到2 log:
public static void Setup()
{
Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository();
hierarchy.Root.RemoveAllAppenders();
PatternLayout patternLayout = new PatternLayout();
patternLayout.ConversionPattern = "%date THREAD [%thread] %logger: %message%newline"; //%-5level
patternLayout.ActivateOptions();
RollingFileAppender infoRoller = new RollingFileAppender();
infoRoller.AppendToFile = true;
infoRoller.File = @"logs'";
infoRoller.RollingStyle = RollingFileAppender.RollingMode.Date;
infoRoller.MaxSizeRollBackups = 3;
infoRoller.Layout = patternLayout;
infoRoller.DatePattern = @"IN'FO'_yyyy-MM-dd.'lo'g";
infoRoller.StaticLogFileName = false;
infoRoller.ActivateOptions();
hierarchy.Root.AddAppender(infoRoller);
//ADDED CODE
RollingFileAppender errorRoller = new RollingFileAppender();
errorRoller.AppendToFile = true;
errorRoller.File = @"logs'";
errorRoller.RollingStyle = RollingFileAppender.RollingMode.Date;
errorRoller.MaxSizeRollBackups = 3;
errorRoller.Layout = patternLayout;
errorRoller.DatePattern = @"ERROR_yyyy-MM-dd.'lo'g";
errorRoller.StaticLogFileName = false;
errorRoller.ActivateOptions();
hierarchy.Root.AddAppender(errorRoller);
MemoryAppender memory = new MemoryAppender();
memory.ActivateOptions();
hierarchy.Root.AddAppender(memory);
hierarchy.Root.Level = Level.Debug;
hierarchy.Configured = true;
}
}
from other class:
private readonly ILog log = LogManager.GetLogger("GENERAL-LOG");
private readonly ILog elog = LogManager.GetLogger("ERROR-LOG");
Logger.Setup();
log.Debug("prova scrittura in file1");
elog.Error("prova errore scrittura in file2");
result:两个日志文件都用两个消息写入。
请建议，非常感谢!
问题是您已将两个appender附加到"root"日志记录器。如果您想要两个记录器，那么您必须将它们附加到特定的记录器。
我已经注释了hierarchy.Root.AddAppender(errorRoller);和hierarchy.Root.AddAppender(infoRoller);，因为它不再需要，因为追加者被追加到相关的记录器而不是根。
找到下面的代码。在这里，我已经将log和elog作为参数传递给该方法，并分别添加了相关的追加器。
private static void Setup2(ILog infoLog, ILog elog)
{
Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository();
hierarchy.Root.RemoveAllAppenders();
PatternLayout patternLayout = new PatternLayout();
patternLayout.ConversionPattern = "%date THREAD [%thread] %logger: %message%newline"; //%-5level
patternLayout.ActivateOptions();
RollingFileAppender infoRoller = new RollingFileAppender();
infoRoller.AppendToFile = true;
infoRoller.File = @"logs'";
infoRoller.RollingStyle = RollingFileAppender.RollingMode.Date;
infoRoller.MaxSizeRollBackups = 3;
infoRoller.Layout = patternLayout;
infoRoller.DatePattern = @"IN'FO'_yyyy-MM-dd.'lo'g";
infoRoller.StaticLogFileName = false;
infoRoller.ActivateOptions();
// hierarchy.Root.AddAppender(infoRoller); //Not appended to the root logger anymore
//ADDED CODE
RollingFileAppender errorRoller = new RollingFileAppender();
errorRoller.AppendToFile = true;
errorRoller.File = @"logs'";
errorRoller.RollingStyle = RollingFileAppender.RollingMode.Date;
errorRoller.MaxSizeRollBackups = 3;
errorRoller.Layout = patternLayout;
errorRoller.DatePattern = @"ERROR_yyyy-MM-dd.'lo'g";
errorRoller.StaticLogFileName = false;
errorRoller.ActivateOptions();
// hierarchy.Root.AddAppender(errorRoller); //Not appended to the root logger anymore
MemoryAppender memory = new MemoryAppender();
memory.ActivateOptions();
hierarchy.Root.AddAppender(memory);
hierarchy.Root.Level = Level.Debug;
hierarchy.Configured = true;
ILog log = infoLog;
Logger logger = (Logger)log.Logger;
logger.AddAppender(errorRoller);
log = elog;
logger = (Logger)log.Logger;
logger.AddAppender(infoRoller);
}
调用方法
private readonly ILog log = LogManager.GetLogger("GENERAL-LOG");
private readonly ILog elog = LogManager.GetLogger("ERROR-LOG");
Logger.Setup2(log,elog);
log.Debug("prova scrittura in file1");
elog.Error("prova errore scrittura in file2");
请将Setup()方法相关的代码块替换为下面的代码块
变化:1. 删除了"hierarchy.Root.AddAppender(infoller);"并注释了"hierarchy.Root.AddAppender(errorRoller);"。2. 删除了"MemoryAppender"，因为在您的情况下似乎不需要。
public static void Setup()
{
Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository();
hierarchy.Root.RemoveAllAppenders();
PatternLayout patternLayout = new PatternLayout();
patternLayout.ConversionPattern = "%date THREAD [%thread] %logger: %message%newline"; //%-5level
patternLayout.ActivateOptions();
ILog log = LogManager.GetLogger("GENERAL-LOG");
Logger l = (Logger)log.Logger;
RollingFileAppender infoRoller = new RollingFileAppender();
infoRoller.AppendToFile = true;
infoRoller.File = @"logs'";
infoRoller.RollingStyle = RollingFileAppender.RollingMode.Date;
infoRoller.MaxSizeRollBackups = 3;
infoRoller.Layout = patternLayout;
infoRoller.DatePattern = @"IN'FO'_yyyy-MM-dd.'lo'g";
infoRoller.StaticLogFileName = false;
infoRoller.ActivateOptions();
l.AddAppender(infoRoller);
//ADDED CODE
ILog elog = LogManager.GetLogger("ERROR-LOG");
Logger el = (Logger)elog.Logger;
RollingFileAppender errorRoller = new RollingFileAppender();
errorRoller.AppendToFile = true;
errorRoller.File = @"logs'";
errorRoller.RollingStyle = RollingFileAppender.RollingMode.Date;
errorRoller.MaxSizeRollBackups = 3;
errorRoller.Layout = patternLayout;
errorRoller.DatePattern = @"ERROR_yyyy-MM-dd.'lo'g";
errorRoller.StaticLogFileName = false;
errorRoller.ActivateOptions();
el.AddAppender(errorRoller);
//hierarchy.Root.AddAppender(errorRoller);
MemoryAppender memory = new MemoryAppender();
memory.ActivateOptions();
hierarchy.Root.AddAppender(memory);
hierarchy.Configured = true;
}
希望这对你有帮助。
谢谢
