JarCastingvertx-mod-guice README 
vertx-mod-guice is a Google Guice module for Vert.x. It includes everything you need to be Guicing your Vert.x like a pro in five minutes.
The easy tutorial
First, create a Guice Module that implements VertxModule
public class MyModule implements VertxModule {
private Container container;
private Vertx vertx;
@Override
public void configure(Binder binder) {
///Do binding stuff here!
binder.bind(MyService.class).to(MyServiceImpl.class);
}
@Override
public void setContainer(Container container) {
this.container = container;
}
@Override
public void setVertx(Vertx vertx) {
this.vertx = vertx;
}
}
Next create your Verticle, extending GuiceVerticle. Using the @GuiceVertxBinding annotation, supply a list of all the Modules the verticle needs at runtime. Use the @Inject annotation to inject any dependencies defined in the modules. You should @Override the onStart() method to kick off any of your normal verticle activity.
@GuiceVertxBinding(modules = {MyModule.class})
public class MyVerticle extends GuiceVerticle {
@Inject
MyService myService;
@Override
public void onStart() {
myService.doStuff();
}
}
Make sure that you include the name of the module in your mod.json for any module that needs to use vertx-mod-guice.

But wait, my Verticles already inherit from some other class!
Not a problem, here is an example for that case.
@GuiceVertxBinding(modules = {MyModule.class})
public class RawVerticle extends Verticle {
@Inject
MyService myService;
@Override
public void start() {
//Just call this firt from the start method
GuiceVerticleHelper.inject(this, vertx, container);
//Proceed as normal
myService.doStuff();
}
}
