我在 spring 应用程序中遇到这个错误(但应用程序运行正常):

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;
}

我真的不明白它来自哪里以及如何修复它。我是这个 Spring 的新手，你能指出如何修复它或者我应该寻找什么吗？我不是在创建/注释 bean。

最佳答案

您可能有不止一个同名 OAuth2ClientContext

要修复它，您可以在其中一种方法中添加 @Qualifier(name='OAuth1')，或者您可以将其中一种方法设置为 @Primary。

例子:

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

或

在您创建Service 的地方，您可以这样做:

@Service
@Primary
public class OAuth2ClientContext{

...
...
..
}
