如何在IntellijIDEA 2016中创建简单的RESTful服务？ （JAX-RS）

Question

My google-fu has failed me.

I have lost 2.5 hours trying to figure this out. I just want to make this simple RESTful service with get and post requests that generate hello world on get (ie localhost:9000/hello ) and on post prints to service console what was sent in bla variable.

I have found some simple examples

import javax.ws.rs.GET;
import javax.ws.rs.Path;

@Path("greeting")
public class Greeter {
    @GET
    public String sayHi() {
        return "Hi!!";
    }
}

But it doesn't work intellij doesnt recognize Path and GET annotations. It asks me if I want to implement them. I've tried on both NewProj->JavaEE->Restful Web Service and NewProj->Java->WebApp->WebServices.

Some sample generated code from one of them made this @webmethod annotation for which I wasn't able to find any info on the net. And the JetBrains video from 2013 looks like an overkill/a-bit-outdated?. This is really simple app, I don't need/know how to use/ Maven.

You need to download the jar-file containing the classes you have imported (from eg http://download.oracle.com/otndocs/jcp/jaxrs-2_0_rev_A-mrel-spec/index.html ).

Open Project Structure, Go to Libraries, press the plus button, and add the jar-file to your project.
