我收到以下响应，并尝试使用JAXB解析它，但下面的代码返回IndexOutOfBoundsException。
我不确定代码有什么问题。我怀疑TotalChargeable和Reckratetotal，试图将它们作为单独的类但没有帮助。
EasytobookResponse response = restTemplate.postForObject(
url, easy, EasytobookResponse.class);

答案 0 :(得分：2)
Response.hotelInfo有@XmlElementWrapper(name="Hotelinfo")和@XmlElement(name="Hotelinfo")，这意味着XML必须是：
<EasytobookResponse>
<Response target="test" username="project121">
<Hotelinfo>
<Hotelinfo>
<Id>436924</Id>
要匹配您的XML，@XmlElement应为Hotel，而不是Hotelinfo。
目前，正在跳过<Hotel>元素，并且没有为Response.hotelInfo列表分配任何内容，因此response.getResponse().getHotelInfo().get(0)失败。
下次，请显示提供异常的行。使我们更容易帮助您。
