log4net未将准确时间记录到DB

Question

我通过log4net设置了数据库日志记录。我得到相同的时间戳，没有异常对象。

Appender：

<appender name="AsyncDBAppender" type="DA.Systems.Focus.Shared.LogCore.AsynchronousAdoNetAppender, Focus-Shared-LogCore">
    <bufferSize value="1" />
    <connectionType value="System.Data.SqlClient.SqlConnection, System.Data, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
    <connectionString value="data source=dbServer;initial catalog=dbName;persist security info=True;user id=username;password=password;MultipleActiveResultSets=True;Connect Timeout=360;App=log4net" />
    <commandText value="INSERT INTO [dbo].[MainLog] ([ProjectId], [ApplicationId], [MachineName],[OperationId], [UserId], [Date],   [Thread] ,[Level],   [Logger], [Message], [Exception])
                                             VALUES (1,           2,               @machineName, @operationId,  @userId,  @logDate, @thread,  @logLevel, @logger,  @message,  @exception)" />

    <parameter>
        <parameterName value="@exception" />

        <size value="4000" />
        <layout type="log4net.Layout.ExceptionLayout" />
    </parameter>
</appender>

产生此日志：

问题：

• 按日期排序将破坏实际序列。模式为log4net.Layout.RawTimeStampLayout，数据库列为Datetime2

• 当有异常时，异常本身未记录

爆炸代码：

try
{
    InfoScope($"{LayerName} -> {callerInfo.MethodName} -> Passes bill created. Notifying Security-System...", userId, operationId);
    var notificationResult = await _securitySystem.FocusBillPaymentNotification(billInfoBdo.BillDetails, userId, operationId);

    if (notificationResult.Result)
    {
        InfoScope($"{LayerName} -> {callerInfo.MethodName} -> Notifying Security-System succeeded: Security-System Receipt #{notificationResult.SecuritySystemReceiptNumber}, Message: {notificationResult.Message}", userId, operationId);
    }
    else
    {
        WarnScope($"{LayerName} -> {callerInfo.MethodName} -> Notifying Security-System failed: {notificationResult.Message}", userId, operationId);
    }
}
catch (Exception exp)
{
    ErrorScope($"{LayerName} -> {callerInfo.MethodName} -> Exception at Security-System Payment notification [{exp.Message}]", exp, userId, operationId);
}

如何使时间戳更精确？

为什么异常pobject无法获取.ToString（）/ logged？

这里是我使用的记录核心：

    #region Error

    [DebuggerStepThrough]
    protected void ErrorScope(string message, string userId, Guid operationId)
    {
        SetUserId(userId);
        SetOperationId(operationId);
        Logger.ErrorFormat(message);
    }

    [DebuggerStepThrough]
    protected void ErrorScope(string message, Exception exception, Guid operationId)
    {
        SetOperationId(operationId);
        Logger.ErrorFormat(message, exception.GetInnerExceptions());
    }

    [DebuggerStepThrough]
    protected void ErrorScope(string message, Exception exception, string userId, Guid operationId)
    {
        SetUserId(userId);
        ErrorScope(message, exception, operationId);
    }

    #endregion

Answer 1

嗯，这不是直接解决此问题的方法，但是我确实设法以另一种方式获得了正确的时间戳：我在数据库中添加了另一列，其类型为DateTime2，默认为SysDateTime()：

RecordStamp DATETIME2 NOT NULL CONSTRAINT DF_MainLog_RecordStamp DEFAULT (SYSDATETIME())

现在，此列负责确保每个日志条目都带有有效的时间戳。
