Access Mule Message from arbitrary place in a thread

问题

With Mule ESB, from an arbitrary class, is it possible to get a handle of the current mule message for that thread? For example, if I create custom log4j appender, can it get access to the mule message and pull data from it?

回答1:

Yes, by using RequestContext.getEvent().getMessage() (javadoc).

And yes, it is deprecated, with this warning:

If access to MuleEvent or MuleMessage is required, then implement a MessageProcessor or Callable instead

But this is not always possible. So using this static helper remains your best option.
