java - 不支持 Spring Social/connect/twitter 请求方法 'GET'

Question

我正在关注 http://spring.io/guides/gs/accessing-twitter/使用 Spring Boot 为 twitter 设置 spring social 但是当我运行应用程序并重定向到 localhost:8080/connect/twitter 我得到:

There was an unexpected error (type=Method Not Allowed, status=405). Request method 'GET' not supported

我知道这与 ConnectController 的映射有关，我该如何真正解决这个问题？

@Controller
public class HelloTwitterController {
    private final Twitter twitter;
    private final ConnectionRepository connectionRepo;

    @Inject
    public MessoTwitterController(Twitter twitter, ConnectionRepository connectionRepo) {
        this.twitter = twitter;
        this.connectionRepo = connectionRepo;
    }

    @RequestMapping(value ="/", method = RequestMethod.GET)
    public String welcomeTwitter (Model model) {
        if (connectionRepo.findPrimaryConnection(Twitter.class) == null)
            return "redirect:/connect/twitter";

        model.addAttribute(twitter.userOperations().getUserProfile());
        model.addAttribute("friends", twitter.friendOperations().getFriends());
        return "welcomeTwitter";
    }
}

@SpringBootApplication
@EnableAutoConfiguration
@ComponentScan("com.mypackage")
public class MyApplication {
       public static void main(String[] args) {
           SpringApplication.run(MyApplication.class, args);
    }
}

Answer 1

您的代码中没有 View 解析器，因此无法呈现 View (返回的字符串)。

您必须添加您的 View 解析器(例如 thymeleaf、freemarker、jsp)或将此行放入 application.properties

spring.social.auto_connection_views=true

这将使用默认模板呈现您的 View 。
