public void scan(BiConsumer<Integer,Annotation> consumer,
                 AnnotatedElement annotatedEle,
                 Predicate<Annotation> filter)

扫描AnnotatedElement上直接声明的注解，调用前需要确保调用support(AnnotatedElement)返回为true

Specified by:

scan in interface AnnotationScanner

Parameters:

consumer - 对获取到的注解和注解对应的层级索引的处理

annotatedEle - AnnotatedElement，可以是Class、Method、Field、Constructor、ReflectPermission
