如何解析java中相对于泛型类或接口的实现类的所有实际类型？

@Test
public void testIndirectlyExtendedGenericSuperclassWithDiffTypeName() {

    abstract class AbstractClass3<AAA, BBB, CCC> { }

    abstract class AbstractClass2<AA, BB, CC> extends AbstractClass3<CC, Map, BB> { }

    abstract class AbstractClass1<A, B> extends AbstractClass2<Long, A, Boolean> { }

    class Impl extends AbstractClass1<String, Integer> {}

    Type[] arr = ActualTypeArgumentsResolver.resolve(Impl.class, AbstractClass3.class);

    Assert.assertTrue(arr.length == 3);
    Assert.assertEquals(arr[0], Boolean.class);
    Assert.assertEquals(arr[1], Map.class);
    Assert.assertEquals(arr[2], String.class);
}
