如何在不键入属性名称的情况下遍历模型和打印

import java.lang.reflect.Field;

public class ModelPrinter {
    public static void printModel(Object model) {
        Class<?> clazz = model.getClass();
        Field[] fields = clazz.getDeclaredFields();
        
        for (Field field : fields) {
            field.setAccessible(true);
            String fieldName = field.getName();
            Object fieldValue;
            try {
                fieldValue = field.get(model);
            } catch (IllegalAccessException e) {
                fieldValue = null;
            }
            System.out.println(fieldName + ": " + fieldValue);
        }
    }
}
