vertx-swagger | Swagger integration in Eclipse Vert | Application Framework library

Well, you started in the wrong direction a bit. Those examples demonstrate how to build VertX application out of Swagger files. What you want is to serve Swagger UI through VertX. I've put an example project for you: https://github.com/AlexeySoshin/VertxSwaggerUI

When you open http://localhost:8080/swagger/ you'll see all Swagger documentation, as usual.

If you want to do that by yourself:

1. Copy https://github.com/swagger-api/swagger-ui/tree/master/dist contents under your resources/webroot
2. Put swagger.json along with those files
3. Create StaticHandler in VertX: router.route("/*").handler(StaticHandler.create());
