phenomenon
SOAService is a bean that passes through two beanpostprocessors one after the other. You will find that the annotation is lost after the proxy.
cglib agent enabled
@SpringBootApplication @EnableAspectJAutoProxy(proxyTargetClass = true) public class Application { public static void main(String[] args) { SpringApplication app = new SpringApplication(Application.class); app.run(args); } }
Why open this agent mode

How to solve this problem
Add @ Inherited to the custom annotation. If it is a third-party annotation, adjust the project interface layer or take this annotation and add @ Inherited annotation through code, or as shown in the figure below.
public Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException { Service anon = bean.getClass().getAnnotation(Service.class); if (anon != null) { try { InvocationHandler h = Proxy.getInvocationHandler(anon); //Set up@Service Annotation supports inheritance, and it should deal with the problem that dynamic proxy causes@Service Missing annotation Field typeField = h.getClass().getDeclaredField("type"); typeField.setAccessible(true); Field annotationTypeField = Class.class.getDeclaredField("annotationType"); annotationTypeField.setAccessible(true); AnnotationType annotationType = (AnnotationType) annotationTypeField.get(typeField.get(h)); Field inheritedField = AnnotationType.class.getDeclaredField("inherited"); this.updateFinalModifiers(inheritedField); inheritedField.set(annotationType, true); // Obtain AnnotationInvocationHandler Of memberValues field Field memberValuesField = h.getClass().getDeclaredField("memberValues"); // Because of this field private final Decorate, so open permissions memberValuesField.setAccessible(true); // Obtain memberValues Map memberValues = (Map) memberValuesField.get(h); Service service = Stream.of(bean.getClass().getInterfaces()) .filter(iface -> iface.getAnnotation(Service.class) != null) .collect(Collectors.toList()) .get(0) .getAnnotation(Service.class); memberValues.put("version", service.version()); memberValues.put("group", service.group()); } catch (Exception e) { throw new BeanCreationException(String.format("%s %s %s %s %s" , "modify" , ClassUtils.getQualifiedName(bean.getClass()) , "Notes on" , ClassUtils.getQualifiedName(Service.class) , "Of group Value sum version Value error") , e); } } return bean; }
