Question

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：

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();
}

Answer 1

确保你正在解组纠正的事情

您需要解组 SOAP正文所保留的内容，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：

好像sb.extractContentAsDocument();没有带来SOAP消息中的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

具有以下内容告诉JAXB，映射到没有显式指定的命名空间的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元素是名称空间限定的。这意味着您的注释应该是以下内容（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

将上述XML用作input.xml我能够解组和编组模型，因为您已使用上述@XmlSchema修复在问题中对其进行了定义。

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);
    }

}

无法解组SOAP响应

确保你正在解组纠正的事情
