Where NOT to set the router BodyHandler

server.groovy

import io.vertx.core.http.HttpMethod
import io.vertx.groovy.ext.web.Router
import io.vertx.groovy.ext.web.handler.BodyHandler

def router = Router.router(vertx)
router.route().handler(BodyHandler.create()) // This works when defined before the routes
def route = router.route(HttpMethod.POST,"/method")
//router.route().handler(BodyHandler.create()) // This will NOT work

route.handler { routingContext ->
    println routingContext.getBodyAsJson()
    routingContext.response()
            .setStatusCode(200)
            .end()
}

vertx.createHttpServer()
        .requestHandler(router.&accept)
        .listen(8080)
