我如何只用反射扫描一堂课

Question

I have two classes Foo and FooBar both of which has some annotated fields. I would like to scan just Foo and not FooBar for the annotated fields. I am currently trying to use org.reflections.Reflections from https://github.com/ronmamo/reflections I have the following:

Set<Field> fields = new Reflections("my.package.Foo", new FieldAnnotationsScanner())
    .getFieldsAnnotatedWith(MyAnnatation.class);

However, this will also pick up fields in FooBar as it starts with the same prefix. How can I construct the Reflections object so as to just scan the one class?

Answer 1

Filtering the results works:

Set<Field> fields = new Reflections("my.package.Foo", new FieldAnnotationsScanner())
    .getFieldsAnnotatedWith(MyAnnatation.class)
    .stream().filter(field -> field.getDeclaringClass().equals(Foo.class))
    .collect(Collectors.toSet());
