spring - 无法使用带有身份验证的假客户端生成的摇摇欲坠，属性无效

我在正确使用swagger生成的伪装客户端时遇到麻烦。我的服务使用密码流为客户端生成令牌，大张旗鼓生成的伪客户端及其配置如下：

伪装客户端配置：

@Configuration
@EnableConfigurationProperties
public class ClientConfiguration {
public ClientConfiguration() {
}

@Bean
@ConditionalOnProperty({"app.security.oAuth2.client-id"})
public OAuth2FeignRequestInterceptor oAuth2RequestInterceptor() {
    return new OAuth2FeignRequestInterceptor(new DefaultOAuth2ClientContext(), this.oAuth2ResourceDetails());
}

@Bean
@ConditionalOnProperty({"app.security.oAuth2.client-id"})
@ConfigurationProperties("app.security.oAuth2")
public ResourceOwnerPasswordResourceDetails oAuth2ResourceDetails() {
    ResourceOwnerPasswordResourceDetails details = new ResourceOwnerPasswordResourceDetails();
    details.setAccessTokenUri("https://localhost:8000/as/token.oauth2");
    return details;
}
}

伪装客户定义：

@FeignClient(name = "${app.name:app}", url = "${app.url:https://localhost}", configuration = {ClientConfiguration.class}
)
public interface FlowApiClient extends FlowApi {
}

我的application.yml

app:
  name: appName
  url: http://localhost:8080
  security:
    oAuth2:
      client-id: 123
      client-secret: 456
      username: test
      password: test

然后我收到以下错误消息：

引起原因：org.springframework.boot.context.properties.source.InvalidConfigurationPropertyNameException：配置属性名称“ app.security.oAuth2”无效
