我使用Common.Logging作为NLog 2.0的包装器。我这样做是为了将来可以用另一个日志提供程序来代替NLog。
我还使用PostSharp,以便在需要时不必编写try catch块。我有一个继承OnMethodBoundaryAspect的类:
问题在于我的表中没有插入任何内容。例如,在我的HomeController的索引页上放置一个记录器,并调用我的logger.Error("an error")时,它会向我的表添加一条记录。
有人可以帮我吗?
我还使用PostSharp,以便在需要时不必编写try catch块。我有一个继承OnMethodBoundaryAspect的类:
[Serializable]
public class LogMethodAttribute : OnMethodBoundaryAspect
{
private ILog logger;
public LogMethodAttribute()
{
this.logger = LogManager.GetCurrentClassLogger();
}
public override void OnEntry(MethodExecutionArgs args)
{
logger.Debug(string.Format("Entering {0}.{1}.", args.Method.DeclaringType.Name, args.Method.Name));
}
public override void OnExit(MethodExecutionArgs args)
{
logger.Debug(string.Format("Leaving {0}.{1}.", args.Method.DeclaringType.Name, args.Method.Name));
}
public override void OnException(MethodExecutionArgs args)
{
logger.Error(args.Exception.Message,args.Exception);
}
}
我已经在我的web.config中按照以下方式配置了Common.Logging:
<configSections>
<sectionGroup name="common">
<section name="logging" type="Common.Logging.ConfigurationSectionHandler, Common.Logging" />
</sectionGroup>
</configSections>
<common>
<logging>
<factoryAdapter type="Common.Logging.NLog.NLogLoggerFactoryAdapter, Common.Logging.NLog20">
<arg key="configType" value="FILE" />
<arg key="configFile" value="~/NLog.config" />
</factoryAdapter>
</logging>
</common>
NLog.Config看起来像这样:
<?xml version="1.0" encoding="utf-8" ?>
<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

this.logger = LogManager.GetCurrentClassLogger();
。在这种情况下,这不会获取与方面类相关的“logger”,而不是修饰类? - RJ Lohan
