无法解组SOAP响应 [英] Can not unmarshall the SOAP response
本文介绍了无法解组SOAP响应的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我可以发送请求并收到回复，但我无法解析回复。它返回以下错误：
I could send a request and receive the response but I can not parse the response. It returns the following error:
Local Name:Body
error is here
java.lang.NullPointerException
at com.ticketmaster.ticketmaster.TicketMaster.Search(TicketMaster.java:119)
at com.ticketmaster.ticketmaster.App.main(App.java:12)
代码
SOAPMessage response
= connection.call(message, endpoint);
connection.close();
SOAPMessage sm = response;
SOAPBody sb = response.getSOAPBody();
System.err.println("Node Name:" + sb.getNodeName()); //return nothing
System.err.println("Local Name:" + sb.getLocalName()); //return Local Name:Body
DOMSource source = new DOMSource(sb);
results = (FindEventsResponse) JAXB.unmarshal(source, FindEventsResponse.class);
System.err.println("Results size: " + this.results.returnTag.results.item.get(0).getName());
} catch (Exception ex) {
System.err.println("error is here");
ex.printStackTrace();
}

基于其中一个以下答案，我整理了结果并显示错误的回复。
Based on one of the following answers, I marshalled the result and it shows a wrong response.

推荐答案
确保你正在解组正确的东西
你需要解组由 SOAP body 保留的内容，而不是整个 SOAP消息。下面是代码的样子：
Ensure You Are Unmarshalling the Correct Thing
You need to unmarshal the content held onto by SOAP body, not the entire SOAP message. Below is what the code might look like:
SOAPMessage sm = response;
SOAPBody sb = response.getSOAPBody();
Document d = sb.extractContentAsDocument();
DOMSource source = new DOMSource(d);
results = (FindEventsResponse) JAXB.unmarshal(source, FindEventsResponse.class);
sb.extractContentAsDocument 的结果即将发生是一个相当于以下的DOM：
The result of sb.extractContentAsDocument is going to be a DOM that is equivalent to the following:
<?xml version="1.0" encoding="UTF-8"?>

UPDATE
基于新例外你得到：
UPDATE
Based on the new exception you are getting:
java.lang.IllegalArgumentException: prefix xsd is not bound to a namespace
at com.sun.xml.internal.bind.DatatypeConverterImpl._parseQName(DatatypeConverterImpl.java:346)
at com.sun.xml.internal.bind.v2.runtime.unmarshaller.LeafPropertyXsiLoader.selectLoader(LeafPropertyXsiLoader.java:75)
at com.sun.xml.internal.bind.v2.runtime.unmarshaller.LeafPropertyXsiLoader.startElement(LeafPropertyXsiLoader.java:58)
at com.sun.xml.internal.bind.v2.runtime.unmarshaller.UnmarshallingContext._startElement(UnmarshallingContext.java:486)
at com.sun.xml.internal.bind.v2.runtime.unmarshaller.UnmarshallingContext.startElement(UnmarshallingContext.java:465)
好像 sb.extractContentAsDocument（）; 没有携带 xmlns：xsd 来自SOAP混乱的声明年龄。相反，您可以更改代码以执行以下操作：
It appears as though sb.extractContentAsDocument(); is not bringing along the xmlns:xsd declaration from the SOAP message. Instead you can change the code to do the following:
SOAPMessage sm = response;
SOAPBody sb = response.getSOAPBody();
DOMSource source = new DOMSource(sb.getFirstChild());
results = (FindEventsResponse) JAXB.unmarshal(source, FindEventsResponse.class);
确保命名空间限定正确映射
具有以下内容告诉JAXB，映射到没有明确指定的命名空间的XML元素的所有内容都应属于 http://ticketmaster.productserve.com/v2/soap.php 命名空间。
@XmlSchema(
namespace = "http://ticketmaster.productserve.com/v2/soap.php",
elementFormDefault = XmlNsForm.QUALIFIED)
package com.ticketmaster.ticketmaster;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
在XML中只有 findEventsResponse 元素是命名空间合格这意味着您的注释应该是以下内容（注意从 QUALIFIED 更改为 UNQUALIFIED ）：
In your XML only the findEventsResponse element is namespace qualified. This means your annotation should be the following instead (note change from QUALIFIED to UNQUALIFIED):
@XmlSchema(
namespace = "http://ticketmaster.productserve.com/v2/soap.php",
elementFormDefault = XmlNsForm.UNQUALIFIED)
package com.ticketmaster.ticketmaster;
import javax.xml.bind.annotation.XmlNsForm;
import javax.xml.bind.annotation.XmlSchema;
演示代码
使用上述XML as input.xml 我能够解组和编组模型，因为你已经在 @XmlSchema 上面提到的修复。
Demo Code
Using the above XML as input.xml I was able to unmarshal and marshal the model as you have defined it in your question with the @XmlSchema fix mentioned above.
import javax.xml.bind.*;
import javax.xml.transform.stream.StreamSource;
public class Demo {
public static void main(String[] args) throws Exception {
JAXBContext jc = JAXBContext.newInstance(FindEventsResponse.class);
Unmarshaller unmarshaller = jc.createUnmarshaller();
StreamSource xml = new StreamSource("src/forum23806625/input.xml");
JAXBElement<FindEventsResponse> response = unmarshaller.unmarshal(xml, FindEventsResponse.class);
Marshaller marshaller = jc.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
marshaller.marshal(response, System.out);
}
}
