[FIXED] How can I get a reference to my deployed verticle after deploying it with Vertx?

Issue

I have a service called TestService which extends AbstractVerticle:

public class TestService extends AbstractVerticle {
  @Override
  public void start() throws Exception {
    //Do things
  }
}

I then deploy that verticle with vertx like this:

Vertx vertx = Vertx.vertx();
vertx.deployVerticle(TestService.class.getName());

How can I get a reference to my deployed TestService after vertx instantiates it?

Solution

You should use an alternative method for deployment:

vertx.deployVerticle(TestService.class.getName(), deployment -> {
  if (deployment.succeeded()) {
    // here is your ID
    String deploymentId = deployment.result();
  } else {
    // deployment failed...
  }
});

If you're just interested in listing all deployed verticles then you can just request the list of ids:

vertx.deploymentIDs()
