           Person person2 = new Person();
           person2.setName("Christoph");
           person2.setAge(22);
   
           DiffNode diff = ObjectDifferBuilder.startBuilding()
                   .inclusion().exclude()
   //                .propertyName("name")
                   .and().build().compare(person1, person2);
           diff.visit((node, visit) -> {
               final Object baseValue = node.canonicalGet(person1);
               final Object workingValue = node.canonicalGet(person2);
               final String message = node.getPath() + " changed from " + baseValue + " to " + workingValue + " change state " + node.getState();
               System.out.println(message);
           });
           System.out.println(diff.hasChanges());
