簡單以Field做驗證, 看看是不是你要的? 不過是簡單寫的, 要用的話結構可能要改改會比較好 ww

public class CheckTest{

    @Test
    public void checkTest1(){
        A a = new A();
        B b = new B();
        var result = Arrays.stream(a.getClass().getDeclaredFields())
                .filter( field -> !field.getName().contains("this$") )
                .filter( fieldA ->
                        Arrays.stream(b.getClass().getDeclaredFields())
                                .anyMatch( fieldB->
                                        fieldB.getName().equals(fieldA.getName())))
                .peek( fieldA -> {
                    try {
                        System.out.println("Check for: " + fieldA.getName()+":" + fieldA.get(a));
                    } catch (IllegalAccessException e) {
                        e.printStackTrace();
                    }
                })
                .allMatch( fieldA ->
                        Arrays.stream(b.getClass().getDeclaredFields())
                                .anyMatch( fieldB->
                                {
                                    try {
                                        return fieldB.get(b).equals(fieldA.get(a));
                                    } catch (IllegalAccessException e) {
                                        e.printStackTrace();
                                    }
                                    return true;
                                }
                                ));

        System.out.println("final result:" + result);

    }

    class A{
        int a = 10;
        String b = "ABC";
        String c = "CDF";
    }

    class B{
        int a = 10;
        String b = "ABC";
        String d = "CDF";
    }

}

output:

Check for: a:10
Check for: b:ABC
final result:true

我看不懂你想做什麼
參考看看這篇 reflection有沒有幫助

用JSONUtil把ojbect serialize成json string

String jsonString = JSONUtil.serialize(your_object);

再用正則表達式，把atttribute name全部抓出來放在listMatches陣列裡

List<String> listMatches = new ArrayList<String>();
Pattern pattern = Pattern.compile("\"([^\"]+)\":");
Matcher matcher = pattern.matcher(jsonString); 
while( matcher.find() ) {            
    listMatches.add( matcher.group() );
}

..兩個object都抓
再用for去比對兩個listMatches裡，是否具有相同的attributes，有就println出來

for(String strA : listMachers1){
    for(String strB : listMachers2){
        if(strA==strB){
            System.out.println(strA);
        }
    }
}   

PS...我沒在寫java，只是用其他語言的邏輯來處理相同的事情，高手還請鞭小力一點，我怕痛
