Vertx logging: access to request context

It looks like common issue: we want to log routing context related data with some custom messages. For request-per-thread apps we used thread-local MDC. But is there any similar solution for Vert.x apps? May be some Vertx logger that works inside event loop and manage all requests.

Thank you.

assuming this is Vert.x-Web you're working with... one approach you could take is to add a Handler<RoutingContext> to the Router and configure it to run on every request. in Java, that might look something like this:

// the Handler with your custom logging
final Handler<RoutingContext> loggingHandler = routingContext -> {
    final HttpServerRequest request = routingContext.request();

    System.out.println(request.getParam("foo"));

    routingContext.next();
};

// use Router.route() to configure a handler that runs on every
// request regardless of method or path
final Router router = Router.router(Vertx.vertx());
router.route().handler(loggingHandler);

hope that helps!
