[JAVA] Test the integrity of the aggregation using ArchUnit ③

Another version of Testing aggregate consistency using ArchUnit ①


    @ArchTest
    static ArchRule aggregate_object_only_be_accessed_from_root =
        classes()
            .that().resideInAPackage("com.example.domain")
            .should().onlyBeAccessed().byClassesThat(new DescribedPredicate<JavaClass>("is AggregateRoot") {
            @Override
            public boolean apply(JavaClass input) {
                return input.getAnnotations().stream().anyMatch(a -> a.toString().equals("AggregateRoot"));
            }
        });

If @AggregateRoot is added to the aggregate root, it can be judged simply. The place to extract annotations should be able to be written a little more beautifully ...
