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
我可以发送请求并接收响应，但我无法解析响应.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();
}

根据以下答案之一，我整理了结果，结果显示错误响应.
Based on one of the following answers, I marshalled the result and it shows a wrong response.
package-info.java
@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;
代码
SOAPBody sb = response.getSOAPBody();
System.err.println(">>"+ sb.getFirstChild().getNodeName());
Iterator itr = sb.getChildElements();
while(itr.hasNext()){
Object element = itr.next();
System.err.println(element + " ");
}
Document d = sb.extractContentAsDocument();
System.err.println("result of d:"+d.getTextContent());
DOMSource source = new DOMSource(d);
results = (FindEventsResponse) JAXB.unmarshal(source, FindEventsResponse.class);
System.err.println("results>"+results.getReturnTag().getResults().getItem().get(0).getName());
错误是

推荐答案
确保你解组了正确的东西
您需要解组由 SOAP 主体 保存的内容，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 的结果将是一个等价于以下内容的 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"?>

更新
基于您收到的新异常:
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)
看起来好像 sb.extractContentAsDocument(); 没有从 SOAP 消息中带来 xmlns:xsd 声明.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);
确保正确映射命名空间资格
具有以下内容告诉 JAXB，所有映射到没有明确指定命名空间的 XML 元素的内容都应该属于 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;
在您的 XML 中，只有 findEventsResponse 元素是命名空间限定的.这意味着您的注释应改为以下内容(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 作为 input.xml 我能够解组和编组模型，正如您在问题中使用上述 @XmlSchema 修复程序定义的那样.
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);
}
}
