没有类型为“org.springframework.security.oauth2.client.registration.ClientRegistrationRepository”的合格bean可用

Question

当我尝试构建我的项目时，我收到此错误消息：

: Unsatisfied dependency expressed through method 'webClient' parameter 0; 
nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: 
No qualifying bean of type 
'org.springframework.security.oauth2.client.registration.ReactiveClientRegistrationRepository' 
available: expected at least 1 bean which qualifies as autowire candidate.

这是我的应用程序。属性：

spring.security.oauth2.client.registration.eipo.authorization-grant-type=client_credentials
spring.security.oauth2.client.registration.eipo.token-uri=https://devapi.somedomain.co.xx/v1/auth/token
spring.security.oauth2.client.registration.eipo.client-id=randomClientId
spring.security.oauth2.client.registration.eipo.client-secret=T#%*sty%xp4^sdxb(e*
spring.main.web-application-type= reactive

这是我的配置类：

@Configuration
public class WebClientConfig {
  @Bean
  WebClient webClient(ReactiveClientRegistrationRepository clientRegistrations) {
      ServerOAuth2AuthorizedClientExchangeFilterFunction oauth =
        new ServerOAuth2AuthorizedClientExchangeFilterFunction(
          clientRegistrations,
          new UnAuthenticatedServerOAuth2AuthorizedClientRepository());
      oauth.setDefaultClientRegistrationId("eipo"); 
      return WebClient.builder()
        .filter(oauth)
        .build();
  }
}

这是服务等级：

@Slf4j
@Service
public class SettlementService
  @Autowired
  private WebClient webClient;

  public void getAuthThenGetResource(){
    ... //trying to get token
    log.info("got token");
    ... //get something from external resource
    log.info("got response");
  }
}

这是pom.xml

我已经包含了它的父级和依赖项部分。这个 pom.xml 可能是原因，但我不确定。 webclient bean 有什么问题？我已经尝试了从 stackoverflow 找到的许多解决方案，但没有一个有效。谢谢你的帮助。

Answer 1

您有两项需要修复。

最重要的是，缺少豆子就是缺少“开胃菜”。在 pom.xml 中替换

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-oauth2-client</artifactId>
    <version>5.3.13.RELEASE</version>
    <type>jar</type>
</dependency>

与

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-oauth2-client</artifactId>
</dependency>

修复后，它会抱怨缺少提供商 ID。将以下内容添加到 application.properties 修复了该问题。您需要将 github 替换为与 eipo 相关的任何提供程序：

spring.security.oauth2.client.registration.eipo.provider=github

Answer 2

有时仅与身份验证相关的应用程序属性和 Maven 配置是不够的。

让我们尝试显式启用 spring 的自动配置属性并创建默认值

ClientRegistrationRepository

build.gradle

dependencies {
    implementation "org.springframework.boot:spring-boot-starter-oauth2-client"
}

Java

@Configuration
@EnableWebSecurity
@EnableAutoConfiguration
@EnableConfigurationProperties(OAuth2ClientProperties.class)
public class OAuth2Config {

    @Bean
    @ConditionalOnMissingBean
    public ClientRegistrationRepository clientRegistrationRepository(
            OAuth2ClientProperties oAuth2ClientProperties) {
        var clientRegistrations =
                List.copyOf(
                        new OAuth2ClientPropertiesMapper(oAuth2ClientProperties)
                                .asClientRegistrations()
                                .values());
        return new InMemoryClientRegistrationRepository(clientRegistrations);
    }
}
