how do i deploy additional verticles?

[jeff3parker]

I'm relatively new to Vertx and I'm strugging how do I bootstrap adding and initializing additional verticles in conjunction with the JerseyVerticle? For example I'd like to push data onto the EventBus from a request and have another verticle handle and respond to it.

How is this done with vertx-jersey + vertx-hk2?

e.g. // The Jersey Resource

   @POST
    @Path("/")
    @Consumes({MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON})
    @Produces(MediaType.TEXT_PLAIN)
    public Response exampleRequest(MonitorRequest request, @Context Vertx vertx) {
    	try {
			vertx.eventBus().send("gather.data", mapper.writeValueAsString(request));
		} catch (JsonProcessingException e) {
			logger.error(e);
		}
    	return Response.status(200).entity("working on request...").build();
    }

// The other Verticle

public class SomeBizService extends AbstractVerticle implements Handler<Message<Void>> {
...
    void init()
    {
     vertx.eventBus().consumer("gather.job.data", this::handle);
  }

	@Override
	public void handle(Message<Void> event) {
		System.out.println("received message to handle "+event.body());
	}
}

It depends how you start your vertx application.

If you start via a Main class, then you can just deploy the JerseyVerticle in addition to your SomeBizService verticle after you have created the vertx instance.

If you run a fat jar (ie. maven-shade-plugin) or via the vertx command line, then you probably want to have a bootstrap verticle that is responsible for deploying the JerseyVerticle and SomeBizService.

As long as vertx-hk2 and vertx-jersey are on the class path, then you can programmatically deploy the JerseyVerticle as described in the README.md:

vertx.deployVerticle(SomeBizService.class.getName(), config);
vertx.deployVerticle("java-hk2:com.englishtown.vertx.jersey.JerseyVerticle", jerseyConfig);
