Java 通過反射擷取父類欄位的方法__Java基礎

    public static <T> T convertJsonRequestToVo(HttpServletRequest request, Class<T> voClass) throws Exception {        request.setCharacterEncoding("utf-8");        String requestBody = HttpServletRequestUtil.readHttpServletRequestBody(request);        Map<String, Object> requestMap = (Map<String, Object>) JSON.parse(requestBody);        return convertMapToVo(requestMap, voClass);    }    public static <T> T convertMapToVo(Map<String, Object> map, Class<T> voClass) throws Exception {        T obj = voClass.newInstance();        if (map.isEmpty())            return obj;        BeanWrapper beanWrapper = new BeanWrapperImpl(obj);        List<String> fieldList = Stream.of(voClass.getDeclaredFields())                .map(Field::getName)                .collect(Collectors.toList());        fieldList.addAll(Stream.of(voClass.getSuperclass().getDeclaredFields())                .map(Field::getName)                .collect(Collectors.toList()));        for (Map.Entry<String, Object> entry : map.entrySet())            if (!StringUtils.isEmpty(String.valueOf(entry.getValue())))                if (fieldList.contains(entry.getKey()))                    beanWrapper.setPropertyValue(entry.getKey(), entry.getValue());        return obj;    }
