無法使用JAXB解析XML響應-IndexOutOfBoundsException

Question

我收到以下響應，並嘗試使用JAXB解析它，但以下代碼返回IndexOutOfBoundsException。

我不確定代碼有什么問題。 我對TotalChargeable和Reckratetotal懷疑，試圖將它們作為單獨的類，但沒有幫助。

EasytobookResponse response = restTemplate.postForObject(
                    url, easy, EasytobookResponse.class);

            System.err.println("RESPONSE >>>>"
                    + response.getResponse().getHotelInfo().get(0).getId());

Answer 1

Response.hotelInfo具有@XmlElementWrapper(name="Hotelinfo")和@XmlElement(name="Hotelinfo") ，這意味着XML需要為：

<EasytobookResponse>
    <Response target="test" username="project121">
        <Hotelinfo>
            <Hotelinfo>
                <Id>436924</Id>

為了匹配您的XML，@ @XmlElement應該是Hotel ，而不是Hotelinfo 。

當前， <Hotel>元素正在被跳過，並且沒有為Response.hotelInfo列表分配任何內容，因此response.getResponse().getHotelInfo().get(0)失敗。
