REST API - 无法使用 JAXB 转换 XML

Question

我在处理 API 响应时遇到问题。首先，我正在建立连接以获取我的回复：

HttpResponse<String> response = Unirest.get(buildUrl(newOrdersUrl)).basicAuth(login, pass).asString();
        if(response.getStatus() == 200){
            return OrdersConverter.convertOrders(response.getBody());
        } else {
            return null;
        }

与：

public class OrdersConverter {
    public static OrdersType convertOrders(String response) {
        try {
            JAXBContext jc = JAXBContext.newInstance(OrdersType.class);
            Unmarshaller u = jc.createUnmarshaller();
            StringBuffer xmlStr = new StringBuffer(response);

            JAXBElement<OrdersType> o = u.unmarshal(new StreamSource(new StringReader(xmlStr.toString())), OrdersType.class);

            return o.getValue();
        } catch (JAXBException e) {
            return null;
        }
    }
}

以此https://sell.fruugo.com/fruugo-docs/fruugo-product-feed.xsd作为架构

我的回复字符串看起来像这样（带有经过编辑的信息）

当我将此响应转换为 OrdersType.class 时，我可以获得我的 merchantID，但我没有从 OrdersType.class 获得订单列表。我错过了什么？我是否需要将此响应转换为另一个 class 以获取订单列表？

我很确定问题出在 xml（响应）的结构与生成的类不匹配。

您提供的 xsd 与您在问题中提供的类不对应，也不与您尝试解组的 xml 对应。我认为您有一些绑定覆盖了 link 中显示的架构的名称等，并且没有提供所有类供我自己尝试。

一种帮助您解决问题的方法是输入 xml 并尝试使用以下代码对其进行解组，您将逐字段获得不匹配的反馈。

        try {
            File file = new File("/path/to/your/file.xml");
            JAXBContext jaxbContext = JAXBContext.newInstance(YouRootClassForOrder.class);

            Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
            jaxbUnmarshaller.setEventHandler(
                    new ValidationEventHandler() {
                        public boolean handleEvent(ValidationEvent event ) {
                            throw new RuntimeException(event.getMessage(),
                                    event.getLinkedException());
                        }
                    });
            YouRootClassForOrder pojo = (YouRootClassForOrder) jaxbUnmarshaller.unmarshal(file);
        } catch (JAXBException e) {
            e.printStackTrace();
        }
