我有一个java类，如下所示：

@RequiredArgsConstructor
    public class Interceptor implements RequestInterceptor {
    
        @Value("${spring.application.name}")
        private final String applicationName;
}

这个类由一个客户端使用：

@FeignClient(
    name = "interceptor",
    url = "${interceptor.url}",
    configuration = Interceptor.class
)
public interface InterceptorApiClient {
}

问题是，当我尝试运行项目时，我得到了这个错误：

Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'java.lang.String' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}

我放了@Component注解，给予了@PropertySource（{“classpath：application.yaml”}），但没有任何变化。
注意：applicationName在application.yaml文件中，如下所示：

spring:
  application:
    name: interceptor-project

知道吗？
