Question

我试图从现有的SOAP Web服务生成一些列表。但是问题是，在尝试生成空值时，总是会得到空值。也许有人可以评论为什么这个问题发生在我身上？谢谢！

我正在做的步骤：

我从WSDL_link生成了wsdl

带有插件的生成的wsdl文件：

<plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>jaxws-maven-plugin</artifactId>
            <version>2.5</version>
            <executions>
                <execution>
                    <goals>
                        <goal>wsimport</goal>
                    </goals>
                    <!-- Following configuration will pass ${project.basedir}/src/remote-xjc/bindings.xjc 
                        and ${project.basedir}/src/jaxws/bindings-default.xjc to wsimport. -->
                    <configuration>
                        <wsdlUrls>
                            <wsdlUrl>${project.basedir}/src/main/resources/wsdl/FxRates_12.wsdl</wsdlUrl>
                        </wsdlUrls>
                    </configuration>
                </execution>
            </executions>
        </plugin>

我使用了这个插件，因为其他插件总是给我错误。并尝试通过以下方式调用它：

@RestController
public class GetRatesController {
private static final String soapEndpointUrl = "http://old.lb.lt/webservices/FxRates/FxRates.asmx";
private static final String soapAction = "http://www.lb.lt/WebServices/FxRates/getCurrencyList";
@RequestMapping(value = "/get", method = RequestMethod.GET, produces = "application/xml")
public ResponseEntity<GetCurrencyListResponse> getIndexView() {
    GetCurrencyListResponse response = new GetCurrencyListResponse();
    try {
        // Create SOAP Connection
        SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
        SOAPConnection soapConnection = soapConnectionFactory.createConnection();
        // Send SOAP Message to SOAP Server
        GetCurrencyList getCurrencyList = new GetCurrencyList();
        SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(soapAction, getCurrencyList), soapEndpointUrl);
        JAXBContext jaxbContext = JAXBContext.newInstance(GetCurrencyListResponse.class);
        Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();
        response = (GetCurrencyListResponse) unmarshaller.unmarshal(soapResponse.getSOAPBody().extractContentAsDocument()); 
    } catch (Exception e) {
        System.err.println("\nError occurred while sending SOAP Request to Server!\nMake sure you have the correct endpoint URL and SOAPAction!\n");
        e.printStackTrace();
    }
    System.out.println(response.getGetCurrencyListResult().getContent());
    return new ResponseEntity<>(response, HttpStatus.OK);
}
private static <T> SOAPMessage createSOAPRequest(String soapAction, T requestClass) throws Exception {
    MessageFactory messageFactory = MessageFactory.newInstance();
    SOAPMessage soapMessage = messageFactory.createMessage();
    createSoapEnvelope(soapMessage, requestClass);
    MimeHeaders headers = soapMessage.getMimeHeaders();
    headers.addHeader("SOAPAction", soapAction);
    soapMessage.saveChanges();
    return soapMessage;
}
private static <T> void createSoapEnvelope(SOAPMessage soapMessage, T requestClass) throws SOAPException, JAXBException {
    SOAPPart soapPart = soapMessage.getSOAPPart();
    SOAPEnvelope envelope = soapPart.getEnvelope();
    JAXBContext jaxbContext = JAXBContext.newInstance(requestClass.getClass());
    Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
    jaxbMarshaller.setProperty(Marshaller.JAXB_FRAGMENT, Boolean.TRUE);
    StringWriter sw = new StringWriter();
    // SOAP Body
    SOAPBody soapBody = envelope.getBody();
    jaxbMarshaller.marshal(requestClass, sw);
    System.out.println(sw.toString());
    soapBody.addTextNode(sw.toString());
}
}

但是我得到的结果为空。哪一部分错了？如何获取货币清单，应返回哪个服务？货币清单服务的XML：XML

从现有的SOAP服务调用服务列表
