说“我想知道在春季实现Twitter登录链接”

Question

我想用Spring实现Twitter登录。现在，我将使用“ spring-social-twitter”。 但是，我从未与Twitter进行合作，因此陷入困境。

我按如下所示实现了它，但是发生了错误。

@RestController
@RequestMapping(value = "/api/v1.0.0/auth")
public class AuthController {

    @Autowired
    private UserService userService;

    private Twitter twitter;
    private ConnectionRepository connectionRepository;

    @Inject
    public AuthController(Twitter twitter, ConnectionRepository connectionRepository) {
        this.twitter = twitter;
        this.connectionRepository = connectionRepository;
    }

    @GetMapping(value="/twitter")
    public String twitterSignin(Model model) {
        if (connectionRepository.findPrimaryConnection(Twitter.class) == null) {
            return "redirect:/connect/twitter";
        }
        model.addAttribute(twitter.userOperations().getUserProfile());
        return "home";
    }
}

当前，发生以下错误。
