Translation of Vert.x 2 to Vert.x 3 !!

[davidr...@gmail.com]

Hi people,

can anyone help me pass the following code from Vert.x 2 to Vert.x 3? Is that I'm doing a client / server websockets

public class WebserverVerticle extends Verticle {

 

@Override

public void start() {

final Pattern chatUrlPattern = Pattern.compile("/chat/(\\w+)");

final EventBus eventBus = vertx.eventBus();

final Logger logger = container.logger();

 

// 1) HTTP Server

RouteMatcher httpRouteMatcher = new RouteMatcher().get("/", new

Handler<HttpServerRequest>() {

@Override

public void handle(final HttpServerRequest request) {

request.response().sendFile("web/chat.html");

}

}).get(".*\\.(css|js)$", new Handler<HttpServerRequest>() {

@Override

public void handle(final HttpServerRequest request) {

request.response().sendFile("web/" + new File(request.path()));

}

});

 

vertx.createHttpServer().requestHandler(httpRouteMatcher).listen(8080, "localhost");

// 2) Websockets Chat Server

vertx.createHttpServer().websocketHandler(new Handler<ServerWebSocket>() {

@Override

public void handle(final ServerWebSocket ws) {

final Matcher m = chatUrlPattern.matcher(ws.path());

if (!m.matches()) {

ws.reject();

return;

}

 

final String chatRoom = m.group(1);

final String id = ws.textHandlerID();

logger.info("registering new connection with id: " + id + " for chat-room: " + chatRoom);

vertx.sharedData().getSet("chat.room." + chatRoom).add(id);

 

ws.closeHandler(new Handler<Void>() {

@Override

public void handle(final Void event) {

logger.info("un-registering connection with id: " + id + " from chat-room: " + chatRoom);

vertx.sharedData().getSet("chat.room." + chatRoom).remove(id);

}

});

 

ws.dataHandler(new Handler<Buffer>() {

@Override

public void handle(final Buffer data) {

 

ObjectMapper m = new ObjectMapper();

try {

JsonNode rootNode = m.readTree(data.toString());

((ObjectNode) rootNode).put("received", new Date().toString());

String jsonOutput = m.writeValueAsString(rootNode);

logger.info("json generated: " + jsonOutput);

for (Object chatter : vertx.sharedData().getSet("chat.room." + chatRoom)) {

eventBus.send((String) chatter, jsonOutput);

}

} catch (IOException e) {

ws.reject();

}

}

});

 

}

}).listen(8090);

}

}

A good place to start would be the docs for vertx-web.

RouteMatcher in Vert.x 2 has been replaced by a much more sophisticated matching mechanism there.
