About
The launcher has several lifecycle methods that you can override in order to add custom code that provide a way to configure the options:
Example
If we want to set some metrics, we could extends the launcher and override the method beforeStartingVertx
public class Launcher extends io.vertx.core.Launcher {
@Override
public void beforeStartingVertx(VertxOptions options) {
options.setMetricsOptions(DropWizard.getMetricsOptions());
}
public static void main(String[] args) {
new Launcher().dispatch(args);
}
}
Idea
In a IDE such as IDEA, you can then create a Run configuration with the launcher as a main class.
