C#-Log4net附加程序始终为空
作者:互联网
我在我的webapi项目中使用log4net(使用autofac和owin).我将此添加到我的控制器
LogManager.GetLogger(typeof(NotificationController));
但是我已经看到没有加载附加程序.在我的配置中我有这个
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
...
<log4net>
<root>
<level value="ALL" />
<appender-ref ref="aiAppender" />
<appender-ref ref="TraceAppender" />
<appender-ref ref="FileAppender" />
</root>
<appender name="aiAppender" type="Microsoft.ApplicationInsights.Log4NetAppender.ApplicationInsightsAppender, Microsoft.ApplicationInsights.Log4NetAppender">
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%message%newline" />
</layout>
</appender>
<appender name="TraceAppender" type="log4net.Appender.TraceAppender">
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d [%t] %-5p %m%n" />
</layout>
</appender>
<appender name="FileAppender" type="log4net.Appender.FileAppender">
<file value="log\server.log" />
<appendToFile value="true" />
<layout type="log4net.Layout.PatternLayout">
<param name="ConversionPattern" value="%d [%t] %-5p %m%n" />
</layout>
</appender>
</log4net>
我没有构建错误,如果我调用此代码,我的代码将运行无错误
logger.Fatal("Error");
但是我没有日志.
更新
将此添加到启动类,但不会更改
public class Startup
{
private static readonly ILog logger = LogManager.GetLogger(typeof(Startup));
public void Configuration(IAppBuilder app)
{
HttpConfiguration config = new HttpConfiguration();
logger.Info("Start application");
解决方法:
必须明确告知Log4Net,您希望它从App.config中读取XML配置.
查看:log4net only works when XmlConfigurator.Configure() is called
在应用程序启动代码中调用静态方法XmlConfigurator.Configure(),或将以下内容添加到解决方案中所有项目的AssemblyInfo.cs中:
[assembly: log4net.Config.XmlConfigurator(Watch = true)]
您可能还会发现,启动后必须立即调用LogManager.GetLogger()-即使记录程序实例未用于任何操作,这似乎也有所不同.
