通过反射机制直接操作属性

import java.lang.reflect.Field;

        nameField.setAccessible(true);
        nameField.set(obj, "Vonkenmo");
        ageField.setAccessible(true);
        ageField.set(obj, 20);
        System.out.println("name:" + nameField.get(obj));
        System.out.println("age :" + ageField.get(obj));
