I have an api that mosly produces and consumes a application/vnd. mime type.
For some endpoints I also want to handle different mime type.
How do I avoid specyfing the produces() and consumes() for every route?

E.g instead of:

    router.route("/user-roles/:email")
            .produces(VENDOR_MIME)
            .consumes(VENDOR_MIME)
            .method(PUT).handler(userRolesCrudHandler::replace);
    router.route("/user-roles/:email")
            .produces(VENDOR_MIME)
            .method(GET).handler(userRolesCrudHandler::read);
    router.route("/user-roles/:email")
            .produces(VENDOR_MIME)
            .method(DELETE).handler(userRolesCrudHandler::delete);
    router.route("/user-roles/:email")
            .produces("text/plain")
            .method(GET).handler(userRolesCrudHandler::readAsText);

Something like:

    router.
            .defaultProduces(VENDOR_MIME)
            .defaultConsumes(VENDOR_MIME)
    router.route("/user-roles/:email")
            .method(PUT).handler(userRolesCrudHandler::replace);
    router.route("/user-roles/:email")
            .method(GET).handler(userRolesCrudHandler::read);
    router.route("/user-roles/:email")
            .method(DELETE).handler(userRolesCrudHandler::delete);
    router.route("/user-roles/:email")
            .produces("text/plain")
            .method(GET).handler(userRolesCrudHandler::readAsText);
