將java對象轉化成Map

附上代碼：

public Map<String, Object> object2Map(Object obj) {
        Map<String, Object> map = new HashMap<>();
        if (obj == null) {
            return map;
        }
        Class clazz = obj.getClass();
        Field[] fields = clazz.getDeclaredFields();
        try {
            for (Field field : fields) {
                field.setAccessible(true);
                map.put(field.getName(), field.get(obj));
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return map;
    }
