Question

我在spring应用程序中遇到此错误（但应用程序运行并正常工作）：

Could not autowire. There is more than one bean of 'OAuth2ClientContext' type.
Beans:
oauth2ClientContext   (OAuth2RestOperationsConfiguration.class)  
oauth2ClientContext   (OAuth2RestOperationsConfiguration.class)  
oauth2ClientContext   (OAuth2RestOperationsConfiguration.class)

@SpringBootApplication
@RestController
@EnableOAuth2Client
@EnableAuthorizationServer
@Order(6)
public class SocialApplication extends WebSecurityConfigurerAdapter {

  @Autowired
  OAuth2ClientContext oauth2ClientContext;
}

我真的无法理解它的来源以及如何解决它。我对这个春天的东西很新，你能指出如何解决它或我应该寻找什么。我没有创建/注释bean。

您可能拥有多个名称为OAuth2ClientContext

的bean

要解决此问题，您可以在其中一种方法中添加@Qualifier(name='OAuth1')，也可以将其中一种设置为@Primary。

示例：

@Autowired
@Qualifier(name = 'service1')
private OAuth2ClientContext oauth;

OR

您创建Service的位置可以执行此操作：

@Service
@Primary
public class OAuth2ClientContext{

...
...
..
}

无法自动装配，有多个bean错误
