...
TgetAnnotation(Class cls, Class annotation)
get Annotation 
return cls.getAnnotation(annotation);
TgetAnnotation(Class componentClass, Class annotationClass)

TgetAnnotation(Class configInterface, Method method, Class annotationType, boolean searchMethodType)
Search for an annotation on a configuration interface method.
