Bidirectional communication from Camel to Vertx socket Server - apache-camel

Question

I am trying to use Camel NettyComponent to communicate with a SocketServer written in Vert.x.
This is my server code:
public class NettyExampleServer {
public final Vertx vertx;
public static final Logger logger = LoggerFactory.getLogger(NettyExampleServer.class);
public static int LISTENING_PORT = 15692;
public NettyExampleServer(Vertx vertx) {
this.vertx = vertx;
}
private NetServer netServer;
private List<String> remoteAddresses = new CopyOnWriteArrayList<String>();
private final AtomicInteger disconnections = new AtomicInteger();
public int getDisconnections(){
return disconnections.get();
}
public List<String> getRemoteAddresses(){
return Collections.unmodifiableList(remoteAddresses);
}
public void run(){
netServer = vertx.createNetServer();
netServer.connectHandler(new Handler<NetSocket>() {
#Override
public void handle(final NetSocket socket) {
remoteAddresses.add(socket.remoteAddress().toString());
socket.closeHandler(new Handler<Void>() {
#Override
public void handle(Void event) {
disconnections.incrementAndGet();
}
});
socket.dataHandler(new Handler<Buffer>() {
#Override
public void handle(Buffer event) {
logger.info("I received {}",event);
socket.write("I am answering");
}
});
}
});
netServer.listen(LISTENING_PORT);
}
public void stop(){
netServer.close();
}
}
I tried to build a Route like the following:
public class NettyRouteBuilder extends RouteBuilder {
public static final String PRODUCER_BUS_NAME = "producerBus";
public static final String CONSUMER_BUS_NAME = "receiverBus";
private Processor processor = new Processor(){
#Override
public void process(Exchange exchange) throws Exception {
exchange.setPattern(ExchangePattern.InOut);
}
};
#Override
public void configure() throws Exception {
from("vertx:" + PRODUCER_BUS_NAME).process(processor).to("netty:tcp://localhost:"+ NettyExampleServer.LISTENING_PORT + "?textline=true&lazyChannelCreation=true&option.child.keepAlive=true").to("vertx:"+CONSUMER_BUS_NAME);
}
}
My tests shows that:
If I eliminate the processor on the route, the delivery succeed but there is no answer by the server
If I keep the processor, the data is delivered to the server but an exception raise because no data is received.
I have created a small project here: https://github.com/edmondo1984/netty-camel-vertx . How do I use Camel Netty Component to create a bidirectional route ?

Answer 1

To communicate Vertx and Camel the best tool is to use one of this:
Camel Vertex endpoint
Vertex Camel connector
You can find an example here
If you could or have another requeriments it is possible also to use a common connector like Netty on the both sides.
