我已经构建了一个简单的应用程序来将我的应用程序与linkedIn 连接起来。我在 Facebook 的 Spring Social Example 应用程序之后对其进行了建模：http: //spring.io/guides/gs/accessing-twitter/

在该教程中，只需在类路径的 application.properties 文件中添加 appId 和 appSecret 即可连接到 Facebook。根据春天的说法，

“类路径中这些属性和 Spring Social Twitter 的存在将触发 Spring Social 的 ConnectController、TwitterConnectionFactory 和 Spring Social 连接框架的其他组件的自动配置。”

因此，我假设为 LinkedIn 做同样的事情会连接相同的连接框架。我制作了一个application.yml文件，其中包含以下属性：

spring:
  social:
    linkedin:
      consumerKey: {{someKey}}
      consumerSecret:{{someSecret}}

然后我做了一个LinkedInController：

@Controller
@RequestMapping("/")
public class LinkedInController {

    private LinkedIn linkedIn;

    private ConnectionRepository userConnectionRepository;

    @Inject
    public LinkedInController(LinkedIn linkedIn, ConnectionRepository userConnectionRepository) {
        this.linkedIn = linkedIn;
        this.userConnectionRepository = userConnectionRepository;
        }

    @RequestMapping(method=RequestMethod.GET)
    public String hello(Model model) {

    if (userConnectionRepository.findPrimaryConnection(LinkedIn.class) == null) {
        return "redirect:/auth/linkedin";
    }

    LinkedInProfile profile = linkedIn.profileOperations().getUserProfile();
    System.out.println(profile.getFirstName());
    return "hello";
    }

}

但是，这不会创建 LinkedInController bean：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'linkedInController' defined in file [/Users/hankekimm/Documents/safx/target/classes/com/safx/web/api/LinkedInController.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [org.springframework.social.linkedin.api.LinkedIn]: : No qualifying bean of type [org.springframework.social.linkedin.api.LinkedIn] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

我不确定这里有什么问题。我的属性文件有问题吗？还是我缺少其他东西？

我知道这是旧帖子。但希望它可以对其他人有所帮助。我有一个类似的问题，问题出在属性文件中。

正确的格式是：

spring:
  social:
    linkedin:
      appId: {{someKey}}
      appSecret:{{someSecret}}
