If so, will all JAX-RS related imports go into the interface?

In the class ResourceConfig, there is a constructor like this

ResourceConfig(Class... classes)

The constructor create a new resource configuration initialized with a given set of resource/provider classes.
So you can extend ResourceConfig to register the implementation class.

public class RestConfig extends ResourceConfig {

    public RestConfig() {
        // register the implementation class
        super(MyServiceImpl.class);
    }

}

Then, configure web.xml.

    Scivantage REST Service
    org.glassfish.jersey.servlet.ServletContainer
    
        javax.ws.rs.Application
        
        foo.bar.RestConfig

But the simplest way is that register the implementation class in web.xml.

    Scivantage REST Service
    org.glassfish.jersey.servlet.ServletContainer
    
        jersey.config.server.provider.classnames
        
        foo.bar.impl.MyServiceImpl
