Override methods from ProviderSigninController/ComectController

What I am trying to achieve is first when trying to connect to a service provider if no session is available - create one and second because my client is not a browser but HttpClient I want the connectionStatus method to return json instead of html?

I tried directly extending from ConnectController but I suspect a lot is happening behind the scenes so not quite clear what exactly the error is telling me:


@Controller
@RequestMapping("/connect")
public class MyConnectController extends ConnectController {

@Inject
public MyConnectController(
ConnectionFactoryLocator connectionFactoryLocator,
ConnectionRepository connectionRepository) {
super(connectionFactoryLocator, connectionRepository);
// TODO Auto-generated constructor stub
}

@RequestMapping(value = "/{providerId}", method = RequestMethod.GET)
public String get(@PathVariable String providerId, NativeWebRequest request) {
return "I'll return a json string here, OK?";
}

@Override
@RequestMapping(value = "/{providerId}", method = RequestMethod.POST)
public RedirectView connect(@PathVariable String providerId,
NativeWebRequest request) {
System.out.println("I'll create a new session here, OK?");
return super.connect(providerId, request);
}
}


and I am getting the following error:
