If you're able to use log4j 1.3, you could use ReflectionFilter. Instead of passing a string in the debug call, pass in a JavaBean (POJO) and the ReflectionFilter will build an MDC entry for each JavaBeans-style attribute available on the object.
The event's message is provided one of two ways: - if you have a 'message' attribute (getMessage method), the result of that method call is used as the event's message. - if a 'message' attribute doesn't exist, toString is used as the event's message.
