Ostatnio trochę zmieniłam schemat, więc moje klasy dziedziczą po super klasie, problem polega na tym, że moja metoda porównywania generuje dziennik kontroli, używając Java, teraz jest tylko zapętlanie pól klasy podrzędnej, a nie nadklasy, jest istnieje sposób, aby uzyskać wszystkie pola? czy muszę go wrzucić do super klasy .....?

Oto moja metoda poniżej:

<code>public static <T> String GenerateChangeLogForEntity(T old, T updated) {
        String text = "";
        try {
            Field[] fields = old.getClass().getDeclaredFields();
            if(fields != null) {
                BaseController.getLogger().info("Z1 num fields:"+fields.length);
                for (Field field : fields) {
                    if(field.isAnnotationPresent(Column.class)) {
                        String fieldName = field.getName();
                        BaseController.getLogger().info(field.getName());
                        if(field.isAnnotationPresent(Variation.class)) {
                            Variation v = field.getAnnotation(Variation.class);
                            fieldName = v.friendlyName();
                        }
                        field.setAccessible(true);
                        if(field.get(old) != null && field.get(updated) != null) {
                            if(!(field.get(old)).equals(field.get(updated))) {
                                text += "<p><span class=\"field-name\">"+fieldName+"</span> changed from: <strong>"+GetFriendlyFieldValueForChangeLog(field.get(old))+"</strong>  to: <strong>"+GetFriendlyFieldValueForChangeLog(field.get(updated)) + "</strong></p>";
                            }
                        }
                        if(field.get(old) == null && field.get(updated) != null) {
                            text += "<p><span class=\"field-name\">"+fieldName+"</span> changed from: <strong>empty</strong> to: <strong>"+GetFriendlyFieldValueForChangeLog(field.get(updated)) + "</strong></p>";
                        }
                        if(field.get(old) != null && field.get(updated) == null) {
                            text += "<p><span class=\"field-name\">"+fieldName+"</span> changed from: <strong>"+GetFriendlyFieldValueForChangeLog(field.get(updated))+"</strong> to <strong>empty</strong>" + "</p>";
                        }
                        field.setAccessible(false);
                    }
                }
            }
        } catch(IllegalAccessException e) {}
        return text;
    }
