java - 使用 JAXB 但未获取值

Question

我尝试使用下面的代码，但没有获取值。

main
{
String example="<SOAP:Envelope xmlns:SOAP=\"http://schemas.xmlsoap.org/soap/envelope/\"><SOAP:Body><ns0:findCustomerResponse xmlns:ns0=\"http://service.jaxws.blog/\"><return id=\"123\"><firstName>Jane</firstName><lastName>Doe</lastName></return></ns0:findCustomerResponse></SOAP:Body></SOAP:Envelope>";
ByteArrayInputStream bas=new ByteArrayInputStream(example.getBytes());
        JAXBContext jc = JAXBContext.newInstance(Customer.class);
        Unmarshaller unmarshaller = jc.createUnmarshaller();
        SOAPMessage message = MessageFactory.newInstance().createMessage(null,
                bas);
        JAXBElement<Customer> jb = unmarshaller.unmarshal(message.getSOAPBody(), Customer.class);

        Customer customer = jb.getValue();
        System.out.println(customer.id);
        System.out.println(customer.firstName);
        System.out.println(customer.lastName);
      }

@XmlAccessorType(XmlAccessType.FIELD)
public class Customer {

    @XmlAttribute
    int id;

    String firstName;

    String lastName;

}

请说明为什么我没有获得值

正如 @Andreas 所说，客户在 SOAP 主体中嵌套了两层，因此如果您想获取它，则可以使用以下内容，但我想说它不是那么优雅:

JAXBElement<Customer> jb = unmarshaller.unmarshal(message.getSOAPBody().getFirstChild().getFirstChild(), Customer.class);
