java - 无法解码 SOAP 响应

转载作者：塔克拉玛干更新时间：2023-11-01 21:55:45

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:

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，它显示了错误的响应。

package-info.java

    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

最佳答案

确保解码正确

您需要解码 SOAP 主体 保留的内容，而不是整个 SOAP 消息。下面是代码的样子:

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 的结果将是一个等同于以下内容的 DOM:

基于您得到的新异常:

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)

似乎 sb.extractContentAsDocument(); 没有从 SOAP 消息中引入 xmlns:xsd 声明。相反，您可以更改代码以执行以下操作:

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限定

以下内容告诉 JAXB，映射到 XML 元素但未明确指定 namespace 的所有内容都应属于 http://ticketmaster.productserve.com/v2/soap.php namespace 。

@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该改为以下内容(注意从 QUALIFIED 更改为 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

使用上面的 XML 作为 input.xml 我能够解码和编码模型，正如您在问题中使用上述 @XmlSchema 修复定义的那样。

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);
    }

}
