将对象转换成 map对象 and hutool 将对象转换成json字符串

     Person person =new Person();
        person.setAdult(true);
        person.setName("1");
        // 将对象转换成json字符串
        String r = JSONUtil.parseObj(person, false).toString();
        System.out.println(r);

将对象转换成 map对象

Map stringObjectMap = objectToMap(person);
System.out.println(stringObjectMap);

public static Map objectToMap(Object obj) throws IllegalAccessException {
        Map map = new HashMap<>();
        Class clazz = obj.getClass();
        for (Field field : clazz.getDeclaredFields()) {
            field.setAccessible(true);
            String fieldName = field.getName();
            Object value = field.get(obj) == null ? "":field.get(obj);
            map.put(fieldName, value);
        }
        return map;
    }
