从企业图书馆5升级到6

Question

我正在将现有的应用程序从5升级到6。我的应用程序是.NET web应用程序。我依赖企业库将任何错误记录到数据库(sql server)。

我的应用程序还使用自定义数据库侦听器和自定义日志异常处理程序(这两种方式都是我的解决方案中单独的.net项目)。

因此，我已经安装了6个，并将以下代码添加到Application_Start-

             IConfigurationSource config = ConfigurationSourceFactory.Create();
        ExceptionPolicyFactory factory = new ExceptionPolicyFactory(config);
        Logger.SetLogWriter(new LogWriterFactory().Create());

        ExceptionManager exceptionManager = factory.CreateManager();

当System.NotImplementedException击中Logger.SetLogWriter(新的LogWriterFactory().Create())；代码行时，就会得到它。

编辑:更详细的错误信息

 System.NotImplementedException was unhandled by user code
 HResult=-2147467263
 Message=Must be implemented by subclasses.
 Source=Microsoft.Practices.EnterpriseLibrary.Logging

我做错了什么？

这是我的web.config-

编辑:感谢@lrb让我走上正确的道路。这是有效的密码-

protected void Application_Start()
{
    LoggingConfiguration loggingConfiguration = BuildLoggingConfig();
    LogWriter logWriter = new LogWriter(loggingConfiguration);
    Logger.SetLogWriter(logWriter, false);
    ExceptionPolicy.SetExceptionManager(exManager);

    // Create the default ExceptionManager object programatically
    exManager = BuildExceptionManagerConfig(logWriter);

    // Create an ExceptionPolicy to illustrate the static HandleException method
    ExceptionPolicy.SetExceptionManager(exManager);

           ...
}

private static LoggingConfiguration BuildLoggingConfig()
{
    // Formatters

    var config = new LoggingConfiguration();

    return config;
}

private static ExceptionManager BuildExceptionManagerConfig(LogWriter logWriter)
{
    var policies = new List<ExceptionPolicyDefinition>();

    var logAndWrap = new List<ExceptionPolicyEntry>
            {

                new ExceptionPolicyEntry(typeof (Exception),
                    PostHandlingAction.ThrowNewException,
                    new IExceptionHandler[]
                     {
                       new WrapHandler("An application error has occurred.",
                         typeof(APIAvailabilityException))
                     })
            };

    policies.Add(new ExceptionPolicyDefinition("Policy", logAndWrap));

    return new ExceptionManager(policies);
}

Answer 1

它有了一点变化。你只需要一个虚拟的ConfugurationSource。这是默认的一切，因为它是，并对我工作。请注意SetLogWriter方法的可选SetLogWriter参数。这些文件指出：

如果已经设置了写入器，则为true抛出异常；否则为false。默认为true。

IConfigurationSource configurationSource = ConfigurationSourceFactory.Create();
LogWriterFactory logWriterFactory = new LogWriterFactory(configurationSource);                
Logger.SetLogWriter(logWriterFactory.Create(),false);
Logger.Write(le);

Answer 2

对于那些仍然有这个问题的人来说，有更多的信息，并且建议的解决方案不起作用。

出现此异常的一个可能原因是，CoreBuildTraceListener方法没有在您的自定义TraceListenerData类中实现(如果使用的话)。

在我的示例中，我必须添加以下内容才能使其工作(代码是特定于我的实现的)：

protected override TraceListener CoreBuildTraceListener(LoggingSettings settings)
{
    return new RollingXmlTraceListener(
        this.FileName,
        this.RollSizeKB,
        this.TimeStampPattern,
        this.RollFileExistsBehavior,
        this.RollInterval,
        this.MaxArchivedFiles);
}
