Logging exceptions to database in NServiceBus
- by IGoor
If an exception occurs in my MessageHandler I want to write the exception details to my database.
How do I do this?
Obviously, I cant just catch the exception, write to database, and rethrow it since NSB rollbacks all changes. (IsTransactional is set to true)
I tried adding logging functionality in a seperate handler, which I caledl using SendLocal if an exception occured, but this does not work:
public void Handle(MessageItem message)
{
try
{
DoWork();
}
catch(Exception exc)
{
Bus.SendLocal(new ExceptionMessage(exc.Message));
throw;
}
}
I also tried using Log4Net with a custom appender, but this also rolled back.
Configure.With()
.Log4Net<DatabaseAppender>(a => a.Log = "Log")
appender:
public class DatabaseAppender : log4net.Appender.AppenderSkeleton
{
public string Log { get; set; }
protected override void Append(log4net.Core.LoggingEvent loggingEvent)
{
if (loggingEvent.ExceptionObject != null)
WriteToDatabase(loggingEvent.ExceptionObject);
}
}
Is there anyway to log unhandled exceptions in the messagehandler when IsTransactional is true?
Thanks in advance.
