How Do Java Method Annotations Work in Conjunction with Method Overriding

How do Java method annotations work in conjunction with method overriding?

Copied verbatim from http://www.eclipse.org/aspectj/doc/released/adk15notebook/annotations.html#annotation-inheritance:

Annotation Inheritance

It is important to understand the rules relating to inheritance of annotations, as these have a bearing on join point matching based on the presence or absence of annotations.

By default annotations are not inherited. Given the following program

        @MyAnnotation
        class Super {
          @Oneway public void foo() {}
        }

        class Sub extends Super {
          public void foo() {}
        }

Then Sub does not have the MyAnnotation annotation, and Sub.foo() is not an @Oneway method, despite the fact that it overrides Super.foo() which is.

If an annotation type has the meta-annotation @Inherited then an annotation of that type on a class will cause the annotation to be inherited by sub-classes. So, in the example above, if the MyAnnotation type had the @Inherited attribute, then Sub would have the MyAnnotation annotation.

@Inherited annotations are not inherited when used to annotate anything other than a type. A type that implements one or more interfaces never inherits any annotations from the interfaces it implements.

Annotation Reflection for Method overrided

Try using AnnotationUtils class from Spring's core.

I think you'll get the annotation from parent's class as you need.

default annotation for method of an interface

Annotation on methods aren't inherited as properly explained in this
answer though if you want to check if the method have the annotation you can explicity write a custom function that will do it for you, also well explained here

Override transactional method

What you are actually asking : is the @Transactional annotation on the method inherited.

Short answer : no. Annotations on methods are never inherited.

Long answer : see this post.
