我对Vertx很新,但我对测试与Spring的集成感兴趣。我用Spring引导来提升这个项目,并部署了两个Verticle。我希望他们使用事件总线相互通信,但是失败了。这是我做过什么:Vertx事件总线不能发送消息到不同的Verticle

  1. 在主要应用:

    @SpringBootApplication 公共类MySpringVertxApplication { @Autowired MyRestAPIServer myRestAPIServer; @Autowired MyRestAPIVerticle MyRestAPIVerticle;

    public static void main(String[] args) { 
    SpringApplication.run(MySpringVertxApplication.class, args); 
    } 
    
    @PostConstruct 
    public void deployVerticles(){ 
    System.out.println("deploying..."); 
    
    Vertx.vertx().deployVerticle(MyRestAPIVerticle); 
    Vertx.vertx().deployVerticle(myRestAPIServer); 
    } 
    

    }

  2. 在APIVerticle:

    @Component 公共类MyRestAPIVerticle延伸AbstractVerticle {

    public static final String ALL_ACCOUNT_LISTING = "com.example.ALL_ACCOUNT_LISTING"; 
    
    @Autowired 
    AccountService accountService; 
    
    EventBus eventBus; 
    
    @Override 
    public void start() throws Exception { 
    super.start(); 
    
    eventBus = vertx.eventBus(); 
    MessageConsumer<String> consumer = eventBus.consumer(MyRestAPIVerticle.ALL_ACCOUNT_LISTING); 
    consumer.handler(message -> { 
        System.out.println("I have received a message: " + message.body()); 
        message.reply("Pretty Good"); 
        }); 
    consumer.completionHandler(res -> { 
        if (res.succeeded()) { 
         System.out.println("The handler registration has reached all nodes"); 
        } else { 
         System.out.println("Registration failed!"); 
        } 
        }); 
    } 
    

    }

  3. 最后ServerVerticle:

    @Service 公共类MyRestAPIServer扩展AbstractVerticle {

    HttpServer server; 
    HttpServerResponse response; 
    
    EventBus eventBus; 
    @Override 
    public void start() throws Exception { 
    
    server = vertx.createHttpServer(); 
    Router router = Router.router(vertx); 
    
    eventBus = vertx.eventBus(); 
    
    router.route("/page1").handler(rc -> { 
        response = rc.response(); 
        response.setChunked(true); 
    
        eventBus.send(MyRestAPIVerticle.ALL_ACCOUNT_LISTING, 
         "Yay! Someone kicked a ball", 
         ar->{ 
         if(ar.succeeded()){ 
          System.out.println("Response is :"+ar.result().body()); 
         } 
         } 
         ); 
    
    }); 
    
    server.requestHandler(router::accept).listen(9999); 
    

    }

但后,我开始它,并访问/第1页,消息无法从ServerVerticle在发送到APIVerticle所有。如果我将事件总线消费者移动到与发件人相同的垂直方向上,则可以接收事件。

发送消息在两个Verticle之间有什么不对吗?我怎样才能使它工作?

在此先感谢。

您在不同的vertx实例进行部署:

Vertx.vertx().deployVerticle(MyRestAPIVerticle); 
Vertx.vertx().deployVerticle(myRestAPIServer); 

试一下:

Vertx vertx = Vertx.vertx(); 
vertx.deployVerticle(MyRestAPIVerticle); 
vertx.deployVerticle(myRestAPIServer);
