@ComponentProfile(summary="Add a mapped diagnostic context for logging; useful for filtering",
                  tag="service,logging,debug")
public class AddExtendedLoggingContext
extends ServiceImp

Add a mapped diagnostic context via MDC.put(String, String).

It can be useful to use a mapped diagnostic context to provide additional information into your logfile if the underlying logging system supports it (e.g. logback or log4j2)

As the diagnostic logging context is thread based; bear in mind that you will lose the context if part of the service execution chain contains a something like PoolingMessageSplitterService or similar (i.e. something with an underlying thread pool that acts on the message).

This is designed to work in conjunction with LoggingContextWorkflowInterceptor as it will add the following items based on object metadata, this is particular useful for above highlighted the scenario with PoolingMessageSplitterService.

• channelid
• workflowid
• messageuniqueid

In the adapter configuration file this class is aliased as add-extended-logging-context-service which is the preferred alternative to the fully qualified classname when building your configuration.
