如何从请求中读取SOAP标头信息并将其添加到spring Web服务中的响应中

Question

我正在研究春季网络服务.我需要在请求和响应消息中添加一些自定义元素.它应该如下所示:

<soapenv:Envelope>
   <soapenv:Header>
      <tid:SplsTID>
         <tid:Trantype>123</tid:Trantype>
         <tid:Tranver>234</tid:Tranver>
      </tid:SplsTID>
   </soapenv:Header>
   <soapenv:Body>
      <get:GetOrderNumberRequest LoggingLevel="REGULAR" MonitorFlag="Y">
         <get:Header>
            <get:TransactionId>111</get:TransactionId>
            <get:SourceSystemId>SOMS</get:SourceSystemId>
            <get:DateTime>2011-11-11T11:11:11</get:DateTime>
         </get:Header>
         <get:Body>
            <get:StaplesOrderNumber RangeFlag="N" ReleaseFlag="N">
               <get:OrderNumber Count="1" End="11" Start="9"/>
            </get:StaplesOrderNumber>
         </get:Body>
      </get:GetOrderNumberRequest>
   </soapenv:Body>
</soapenv:Envelope>

我能够追加<tid:SplsTID>下<soapenv:Header>通过修改WSDL文件的请求.看起来像这样:

<wsdl:message name="GetOrderNumberRequest">
        <wsdl:part element="tns:GetOrderNumberRequest" name="GetOrderNumberRequest">
        </wsdl:part>
        <wsdl:part element="sch1:SplsTID" name="SplsTID">
        </wsdl:part>
    </wsdl:message>
    <wsdl:message name="GetOrderNumberResponse">
        <wsdl:part element="tns:GetOrderNumberResponse" name="GetOrderNumberResponse">
        </wsdl:part>
        <wsdl:part element="sch1:SplsTID" name="SplsTID">
        </wsdl:part>
    </wsdl:message>
    <wsdl:portType name="ONAS">
        <wsdl:operation name="GetOrderNumber">
            <wsdl:input message="tns:GetOrderNumberRequest" name="GetOrderNumberRequest">
            </wsdl:input>
            <wsdl:output message="tns:GetOrderNumberResponse" name="GetOrderNumberResponse">
            </wsdl:output>
        </wsdl:operation>
    </wsdl:portType>

问题是,我想<tid:SplsTID>从请求中读取部分并希望将其附加到响应的soap标题部分,这是没有发生的.我正在使用基于注释的终点.什么是读取soap标头的代码,并在响应中附加相同的代码.

目前我的终点课是:

@Endpoint
public class OrderNumberServiceEndPoint {
    public static final String NAMESPACE_URI = "http://schemas.staples.com/onas/getOrderNumber";

    /**
     * The local name of the expected request.
     */
    public static final String REQUEST_LOCAL_NAME = "GetOrderNumberRequest";

    /**
     * The local name of the created response.
     */
    public static final String RESPONSE_LOCAL_NAME = "GetOrderNumberResponse";

    private GetOrderNumberService getOrderNumberService;

    public void setGetOrderNumberService(
            GetOrderNumberService getOrderNumberService) {
        this.getOrderNumberService = getOrderNumberService;
    }

    @PayloadRoot(localPart = REQUEST_LOCAL_NAME, namespace = NAMESPACE_URI)
    public GetOrderNumberResponse processOrderNumberRequest(
            GetOrderNumberRequest request) throws Exception {
        GetOrderNumberResponse response = null;
        try{
        response = getOrderNumberService.executeRequest(request);
        }catch(CannotCreateTransactionException e){
            logger.error(ErrorConstants.ERROR_E17);
            throw new ServiceException(ErrorConstants.ERROR_E17);
        }
        return response;
    }

}

最后,我成功地从请求中读取了soap标题并附加到响应中.这就是我的终点方法现在的样子:

 @PayloadRoot(localPart = REQUEST_LOCAL_NAME, namespace = NAMESPACE_URI)
    @ResponsePayload
    public GetOrderNumberResponse processOrderNumberRequest(
            @RequestPayload GetOrderNumberRequest request,
            MessageContext messageContext) throws Exception {
        logger.info("Request Received");
        // read SOAP Header from request and append in response
        SaajSoapMessage soapRequest = (SaajSoapMessage) messageContext
                .getRequest();
        SoapHeader reqheader = soapRequest.getSoapHeader();
        SaajSoapMessage soapResponse = (SaajSoapMessage) messageContext
                .getResponse();
        SoapHeader respheader = soapResponse.getSoapHeader();
        TransformerFactory transformerFactory = TransformerFactory
                .newInstance();
        Transformer transformer = transformerFactory.newTransformer();
        Iterator<SoapHeaderElement> itr = reqheader.examineAllHeaderElements();
        while (itr.hasNext()) {
            SoapHeaderElement ele = itr.next();
            transformer.transform(ele.getSource(), respheader.getResult());
        }
        // process the request PayLoad
        GetOrderNumberResponse response = null;
        try {
            response = getOrderNumberService.executeRequest(request);
        } catch (CannotCreateTransactionException e) {
            logger.error(ErrorConstants.ERROR_E17);
            throw new ServiceException(ErrorConstants.ERROR_E17);
        }
        logger.info("Response Sent");
        return response;
    }

Answer 2

这可能只是您需要的答案的一半，但我认为您可以通过从消息上下文获取 (Saaj)SoapMessage 来读取肥皂头，如下所示：

@PayloadRoot(
    localPart = "GetHiredCandidatesRequest", 
    namespace = DEFAULT_NAMESPACE
)
@ResponsePayload
public GetHiredCandidatesResponse getKandidaat (
    @RequestPayload GetHiredCandidatesRequest getCandidate,
    MessageContext messageContext) {

    SaajSoapMessage request = (SaajSoapMessage) messageContext.getRequest();
    SoapHeader header = request.getSoapHeader();

    GetHiredCandidatesResponse response = objectFactory.createGetHiredCandidatesResponse();
    response.getCandidate().addAll(
        candidateService.getHiredCandidates(
            getCandidate.getFrom(), 
            getCandidate.getTo()
        )
    );

    return response;
}

从版本 2 开始，您可以自动将一些对象“添加”到方法的签名中，就像我在MessageContext此处添加的那样。例如，我用它来从肥皂消息中获取附件。您也可以使用 的其他子类AbstractSoapMessage，因为该getSoapHeder方法位于该类中。

[编辑]顺便说一句：也许您也可以使用拦截器，因为那里提供了请求/响应。查看 org.springframework.ws.soap.server.endpoint.interceptor 包中的一些默认示例。[/编辑]
