java - 解析的 SOAP 响应与收到的响应不同

Question

我正在尝试解析 SOAP 响应。我可以使用以下行显示完整的响应。

  System.out.println("Response: " + out.toString()); 

但是，当我解析响应并编码解析的响应时，它显示错误的响应。

package-info.java

@XmlSchema( 
    namespace = "http://v3.hotel.wsapi.ean.com/",
    elementFormDefault = XmlNsForm.QUALIFIED) 
package com.ean;

import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;

如何解决问题

在正确的级别解码

当前您正在解码与 soap:Body 元素相对应的 XML 节点，而是需要向下导航到 HotelListResponse 元素并对其进行解码。

您可以尝试以下方法:

DOMSource source = new DOMSource(sb.getFirstChild().getFirstChild());

注意您的命名空间资格

在您编码的 XML 中，所有元素均显示为通过 http://v3.hotel.wsapi.ean.com/ 进行限定，但您尝试解码的文档却没有具有此命名空间限定，因此您应该从 package-info 类中删除 @XmlSchema 注释。

使用Unmarshaller而不是JAXB.unmarshal

而不是执行以下操作:

results = (HotelListResponse) JAXB.unmarshal(source, HotelListResponse.class);

我建议这样做:

JAXBContext jc = JAXBContext.newInstance(HotelListResponse.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
results = unmarshaller.unmarshal(source, HotelListResponse.class).getValue();

现在发生了什么

当您使用采用类参数的 unmarshal 方法时，您是在告诉 JAXB XML 对应的类，而不是由根元素自动确定它。

results = (HotelListResponse) JAXB.unmarshal(source, HotelListResponse.class)

由于 XML 文档的级别错误，JAXB 无法将其与您的域模型进行匹配。因此仅填充默认值。这就是为什么结果充满 0 或 false 值的原因。

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<HotelListResponse xmlns="http://v3.hotel.wsapi.ean.com/">
    <numberOfRoomsRequested>0</numberOfRoomsRequested>
    <moreResultsAvailable>false</moreResultsAvailable>
    <HotelList size="0" activePropertyCount="0"/>
</HotelListResponse>
