我确定我缺少一些基本知识。我正在尝试在XUnit集成测试中启用log4net日志记录,但是没有日志文件写入磁盘。
我尝试同时使用配置文件和以编程方式指定日志配置:
配置文件:
<log4net>
<root>
<level value="INFO" />
<appender-ref ref="console" />
<appender-ref ref="file" />
</root>
<appender name="file" type="log4net.Appender.RollingFileAppender">
<file value="mylog.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline" />
</layout>
</appender>
</log4net>
以编程方式
private void ConfigureAppender()
{
var layout = new PatternLayout("%date [%thread] %level %logger - %message%newline");
var appender = new RollingFileAppender {Name = "file", File = "c:\\temp\\mylog.log", AppendToFile = true, RollingStyle = RollingFileAppender.RollingMode.Size, MaxSizeRollBackups = 5, MaximumFileSize = "10MB", StaticLogFileName = true, Layout = layout};
var repository = LogManager.GetRepository() as Hierarchy;
repository.Root.AddAppender(appender);
repository.Root.Level = Level.Info;
repository.Configured = true;
repository.RaiseConfigurationChanged(EventArgs.Empty);
}
然后我使用这种方法(我也尝试过[assembly: XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
)在程序执行的尽可能早的时候得到记录器:
var fileInfo = new FileInfo("log4net.config");
if (!fileInfo.Exists) throw new Exception();
XmlConfigurator.Configure(fileInfo);
var log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
log.Fatal("This is a test");
两种方式均无日志。无论是通过config还是以编程方式定义日志记录,当我检查日志对象时,我都会在底部看到屏幕截图。请注意以下几点:
有人可以告诉我我想念什么吗?
编辑: 根据Z.R.T.的答案,这就是我想念的:
logger
元素。 LogManager.GetLogger("IntegrationLogger");
。一旦我添加了这两件事,log4net就开始工作。唯一的缺点是,所有日志都标记有“ IntegrationLogger”,而不是生成日志的类,但这至少开始了日志记录。
答案 0 :(得分:2)
log4net.config -设置副本(如果较新或始终复制)
<log4net>
<appender name="SomeRollingLogFileAppender" type="log4net.Appender.RollingFileAppender">
<file value="..\\logs\\loginfo.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="10MB" />
<staticLogFileName value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline" />
</layout>
</appender>
<appender name="console" type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread] %level %logger - %message%newline" />
</layout>
</appender>
<logger name="SomeLogger">
<level value="INFO" />
<appender-ref ref="SomeRollingLogFileAppender" />
<appender-ref ref="console" />
</logger>
</log4net>
