无法解组SOAP响应
我可以发送请求并收到响应，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) 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(); }

基于以下答案之一，我整理了结果并显示错误的响应。

确保你解开正确的事情
您需要解组SOAP主体保留的内容，而不是整个SOAP消息 。 以下是代码的外观：
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的结果将是一个等效于以下内容的DOM：

UPDATE
基于您获得的新例外：
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)
好像是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UNQUALIFIED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我能够解组和编组模型，因为您已经使用上面提到的@XmlSchema修复程序在您的问题中定义了它。
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 response = unmarshaller.unmarshal(xml, FindEventsResponse.class); Marshaller marshaller = jc.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); marshaller.marshal(response, System.out); } }
