No way to extends from SpringService and use own configuration. Parametrized value in Application class used for generic create configuration (see final method `io.dropwizard.Application#getConfigurationClass()`)

application

	public class Application extends SpringService<MyConfiguration>{

	    public static void main(String[] args) throws Exception {
	        new Application().run(args);
	    }

	    @Override
	    public String getName() {
	        return "My app";
	    }
	}

configuration

	public class MyConfiguration extends SpringServiceConfiguration{
	    private String myValue;

	    public String getMyValue() {
	        return myValue;
	    }

	    public void setMyValue(final String myValue) {
	        this.myValue = myValue;
	    }
	}


yaml config

	#......
