无法获取requestMapping注解

[wellphoon]

provider service 为代理类是无法获取RequestMapping注解
public void createProvider(Object serviceImpl) {

    Method[] methodList = serviceImpl.getClass().getMethods();
           for (Method method : methodList) {
                     // serviceImpl是JDK动态代理或cglib代理是注解为空
        RequestMapping mapping = method.getAnnotation(RequestMapping.class);
        .....

}
