選擇Verticle名稱以從Maven shell開始

Question

我有一個基於Maven的Vert-x應用程序，它包含一個Java Verticle。目前，我開始與應用：

java -jar jarfile.jar 

現在我需要另一個Verticle添加到項目中。如何選擇以Maven開頭的Verticle？ 謝謝

Answer 1

在Vertx中有一個DeploymentOptions，並且vertx提供了多個Verticles部署選項。

讓我們看看你有MainVerticle和另一verticle爲DemoVerticle：

public class MainVerticle extends AbstractVerticle { 

    @Override 
    public void start(Future<Void> startFuture) throws Exception { 
    vertx = this.getVertx(); 

    // you can configure deployment option 

    final DeploymentOptions deployOptions1 = new DeploymentOptions(); 

    // using below way you can deploy multiple Verticles 
    vertx.deployVerticle(DemoVerticle.class.getName(), deployOptions1 , deployResult -> { 
       if (deployResult.succeeded()) { 
        LOG.info(" [SUCCESS] --> " + deployResult.result()); 
       } else { 
        LOG.error(" [ERROR] --> " + deployResult.cause()); 
       } 
      }); 

    } 
} 

在pom.xml中，你只需要定義上面的例子MainVerticle開始在樹蔭插件主類，所以部署其他Verticles

我希望這將幫助你:)

既然你似乎是使用發牛逼罐子，你是最有可能使用Vertx啓動

http://vertx.io/docs/vertx-core/java/#_the_vert_x_launcher

，它允許您定義主verticle運行
