無法自動裝配，有多個bean錯誤

Question

我在spring應用程序中有這個錯誤（但是應用程序運行並正常工作）：

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;
}

我真的無法理解它來自何處以及如何解決它。 我對這個春天的東西很新，你能指出如何解決它或我應該尋找什么。 我不是在創建/注釋bean。

Answer 1

您可能有多個具有相同OAuth2ClientContext名稱的OAuth2ClientContext

要修復它，您可以在其中一個方法中添加@Qualifier(name='OAuth1') ，也可以將其中一個設置為@Primary 。

例：

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

要么

在您創建Service您可以這樣做：

@Service
@Primary
public class OAuth2ClientContext{

...
...
..
}
