Take a look at MDC ( Mapped Diagnostic Context ): manual/mdc.html ( it is also there in native log4j )

While the MDC manages contextual information on a per thread basis, what you can do is have a request scoped bean which would have from session autowired:Code:
@Autowired
private fromSession session;
And would have set the session ID to the MDC. This way, you'll have this ID available in all the logging throughout this thread.
