this JokeController worked for me, not the one on the repository

[mmaurier]

@RestController
public class JokeController {

private JokeService jokeService;

@Autowired
public JokeController(JokeService jokeService) {
    this.jokeService = jokeService;
}

@RequestMapping("/norris")
public String showJoke() {

// public Model showJoke(Model model) {

// model.addAttribute("joke", jokeService.getJoke());
// return model;
return jokeService.getJoke();

}

}
