ApplicationPath annotation isn't getting picked up

[girdharshubham]

Hi.
I'm trying to put together a vert.x application with resteasy. While the application gets loaded and the server starts up. I expected /v1/health to work but it just throws a 404

Main.java

public class Main extends AbstractVerticle {
    private static VertxResteasyDeployment deployment;

    public static void main(String[] args) {
        Vertx vertx = Vertx.vertx();

        deployment = new VertxResteasyDeployment();
        deployment.setApplicationClass("starter.rx.endpoint.V1");
        deployment.start();
        vertx.deployVerticle("starter.rx.Main");
    }

    @Override
    public Completable rxStart() {
        VertxRequestHandler handler = new VertxRequestHandler(vertx.getDelegate(), deployment);

        return vertx.createHttpServer()
                .requestHandler(x -> handler.handle(x.getDelegate()))
                .rxListen(80)
                .ignoreElement();
    }
}

V1.java

@ApplicationPath("v1")
public class V1 extends Application {
    private final Set<Object> singletons = new HashSet<>();

    public V1() {
        singletons.add(new Management());
    }

    @Override
    public Set<Object> getSingletons() {
        return singletons;
    }
}

Management.java

@Path("")
public class Management {
    @GET
    @Path("health")
    public CompletionStage<String> health() {
        return Flowable.just("healthy").singleStage("");
    }
}

What version of RESTEasy are you using?

[girdharshubham]

      "io.vertx" % "vertx-core" % "4.3.1",
      "org.jboss.resteasy" % "resteasy-vertx" % "6.0.1.Final",
      "io.vertx" % "vertx-rx-java3" % "4.3.1",

These are the libs that I'm using

[jamezp]

I'm guessing you need something like this https://github.com/resteasy/resteasy/blob/6.0.1.Final/server-adapters/resteasy-vertx/src/main/java/org/jboss/resteasy/plugins/server/vertx/VertxJaxrsServer.java#L63-L110 or to simply just use the VertxJaxrsServer directly. I would likely suggest the latter.

Another option would be to upgrade to 6.1.0.Beta2, should be final very soon, and use the new SeBootstrap API in Jakarta RESTful Web Services 3.1. That would look something like:

final CountDownLatch latch = new CountDownLatch(1);
SeBootstrap.start(RestActivator.class, SeBootstrap.Configuration.builder()
                .build())
        .thenApply(instance -> {
            try (Client client = ClientBuilder.newClient()) {
                System.out.println(client.target(instance.configuration().baseUriBuilder().path("/info"))
                        .request()
                        .get()
                        .readEntity(String.class));
            }
            return instance;
        }).whenComplete((instance, error) -> {
            if (error != null) {
                error.printStackTrace();
            }
            try {
                instance.stop().toCompletableFuture().get();
            } catch (InterruptedException | ExecutionException e) {
                throw new RuntimeException(e);
            }
            latch.countDown();
        });
latch.await(10, TimeUnit.SECONDS);

Thanks, @jamezp.
I was wondering if I could make it work without using VertxJaxrsServer but if not, I could try that as well.
Only asking because I wanted to try it with the rxified api.

[jamezp]

No problem. There is a chance, but you just need to configure the paths like the VertxJaxrsServer does is all. There are options to set the VertxOptions if you're trying to configure a specific Vertx.
