I can use org.reflection to get package classes using wildcard?

问题

I was using

Reflections reflections = new Reflections("com.mypackage.root", new MethodAnnotationsScanner()); 

But with this aproach i get back a lot of annotations in packages level that i don't need... What i really want for, is something like this, using an wildcard to get back the deep package level only.

Reflections reflections = new Reflections("com.mypackage.root.*.deep", new MethodAnnotationsScanner())

Because the methods that i really need is in ".deep" package level... I try a lot of combinations with FilterBuilder, then i don't know if i am doing something wrong or this is not possible with this API

回答1:

Try

Reflections reflections = new Reflections("com.mypackage.root", new MethodAnnotationsScanner());

Set<Method> methods = reflections
        .getMethodsAnnotatedWith(MyAnnotation.class).stream()
        .filter(method -> method.getDeclaringClass().getPackage().getName().matches("com.mypackage.root.*.deep"))
        .collect(Collectors.toSet());
