올바른 것을 비 정렬 화하고 있는지 확인

전체 SOAP 메시지가 아니라 SOAP 본문이 보유한 내용을 비 정렬 화해야 합니다 . 다음은 코드의 모습입니다.

SOAPMessage sm = response;
SOAPBody sb = response.getSOAPBody();
Document d = sb.extractContentAsDocument();
DOMSource source = new DOMSource(d);
results = (FindEventsResponse) JAXB.unmarshal(source, FindEventsResponse.class);

의 결과 sb.extractContentAsDocument는 다음과 같은 DOM이됩니다.

네임 스페이스 한정이 올바르게 매핑되었는지 확인

다음은 명시 적으로 지정된 네임 스페이스없이 XML 요소에 매핑 된 모든 것이 네임 스페이스에 속해야 함을 JAXB에 알려줍니다 http://ticketmaster.productserve.com/v2/soap.php.

@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;

XML에서 findEventsResponse요소는 정규화 된 네임 스페이스입니다. 즉, 주석은 대신 다음과 같아야합니다 (에서 QUALIFIED로 변경됨 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;

데모 코드

위의 XML을 사용하여 위에서 언급 한 수정으로 input.xml질문에서 정의한대로 모델을 마샬링 및 마샬링 할 수있었습니다 @XmlSchema.

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);
    }
