使用AXIS2创建的ADB-stub在客户端获取原始XML SOAP响应

Question

我使用AXIS2创建的ADB-stub访问SOAP服务.我想记录服务返回的任何Axis Fault的原始XML响应.我可以将这些错误视为"ServiceError".但是,我找不到一种方法来检索原始XML(参见下面的示例).

我找到了一种使用getOMElement访问原始XML请求/响应以进行常规处理的方法(参见下面的示例).但是,这不适用于故障.

如何使用ADB存根获取原始XML错误？

示例Java代码:

    public void testRequest(String URL) throws AxisFault {
        MyServiceStub myservice = new MyServiceStub(URL);
        MyRequest req = new MyRequest();
        try {
            TypeMyFunctionResponse response = myservice.myFunction(req);

            // logging full soap response
            System.out.println("SOAP Response: "
                    + response.getOMElement(null,
                            OMAbstractFactory.getOMFactory())
                            .toStringWithConsume());
        } catch (RemoteException e) {
            //...
        } catch (ServiceError e) {
            // how to get the raw xml?
        }
    }

示例故障响应,我想获取并记录:

<?xml version='1.0' encoding='UTF-8'?>
<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
    <soapenv:Body>
        <soapenv:Fault>
            <soapenv:Code>
                <soapenv:Value>soapenv:Receiver</soapenv:Value>
            </soapenv:Code>
            <soapenv:Reason>
                <soapenv:Text xml:lang="en-US">service error</soapenv:Text>
            </soapenv:Reason>
            <soapenv:Detail>
                <ns1:error xmlns:ns1="http://www.somehost.com/webservices/someservice">
                    <ns1:code>500</ns1:code>
                    <ns1:messageText>some fault message</ns1:messageText>
                </ns1:error>
            </soapenv:Detail>
        </soapenv:Fault>
    </soapenv:Body>
</soapenv:Envelope>

Answer 1

以下是您可能正在寻找的内容,yourStub是您通过wsdl2java生成的内容,并在您提出请求后使用下面的行.lastOperation当您拨打实际电话时,该消息设置为并发送:

request = yourStub._getServiceClient().getLastOperationContext().getMessageContext("Out")
              .getEnvelope().toString());

response = yourStub._getServiceClient().getLastOperationContext().getMessageContext("In")
              .getEnvelope().toString());

希望这很有帮助.

虽然这个问题已经得到了很好的回答,但我需要提前做到这一点,并且无法找到适合我的约束的合适答案,因此我为后代添加了自己的答案.

对于最近运行JDK 1.4的项目,我需要使用Axis 2版本1.4.1执行此操作,而JAX-WS存根不支持我所阅读的内容.我最后通过使用我自己的构建器类包装SoapBuilder来捕获输入时保留ADB存根,复制输入流并将副本传递给SoapBuilder:

public class SOAPBuilderWrapper implements Builder {
    private String lastResponse;

    private SOAPBuilder builder = new SOAPBuilder();

    private static final int BUFFER_SIZE = 8192;

    public OMElement processDocument(InputStream inputStream,
            String contentType, MessageContext messageContext) throws AxisFault {
        ByteArrayOutputStream copiedStream = new ByteArrayOutputStream();
        try {
            byte[] buffer = new byte[BUFFER_SIZE];
            int bytesRead = inputStream.read(buffer);
            while (bytesRead > -1) {
                copiedStream.write(buffer, 0, bytesRead);
                bytesRead = inputStream.read(buffer);
            }
            lastResponse = copiedStream.toString();

        } catch (IOException e) {
            throw new AxisFault("Can't read from input stream", e);
        }
        return builder.processDocument(
                new ByteArrayInputStream(copiedStream.toByteArray()),
                contentType, messageContext);
    }

    public String getLastResponse() {
        return lastResponse;
    }
}

由于各种原因,使用axis2.xml进行配置存在问题,因此以编程方式添加了包装器,其中包含以下内容:

SoapBuilderWrapper responseCaptor = new SoapBuilderWrapper();
AxisConfiguration axisConfig = stub._getServiceClient().getAxisConfiguration();
axisConfig.addMessageBuilder("application/soap+xml", responseCaptor);
axisConfig.addMessageBuilder("text/xml", responseCaptor);

这允许在调用服务后使用responseCaptor.getLastResponse()检索响应.

按照 joergl 的建议，我使用“SOAPHandler”将我的 ADB-stubs 更改为 JAX-WS-ones，以按照此处的描述记录请求、响应和故障：http://www.mkyong.com/webservices/jax-ws/jax -ws-soap-handler-in-client-side/

我的处理程序如下所示，用于使用 log4j 记录格式良好的 XML：

public class RequestResponseHandler  implements SOAPHandler<SOAPMessageContext> {

    private static Logger log = Logger.getLogger(RequestResponseHandler.class);
    private Transformer transformer = null;
    private DocumentBuilderFactory docBuilderFactory = null;
    private DocumentBuilder docBuilder = null;

    public RequestResponseHandler() {
        try {
            transformer = TransformerFactory.newInstance().newTransformer();
            transformer.setOutputProperty(OutputKeys.INDENT, "yes");
            transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "5");
            docBuilderFactory = DocumentBuilderFactory.newInstance();
            docBuilder = docBuilderFactory.newDocumentBuilder();
        } catch (TransformerConfigurationException
                | TransformerFactoryConfigurationError
                | ParserConfigurationException e) {
            log.error(e.getMessage(), e);
        }
    }

    @Override
    public void close(MessageContext arg0) {
    }

    @Override
    public boolean handleFault(SOAPMessageContext messageContext) {
        log(messageContext);
        return true;
    }

    @Override
    public boolean handleMessage(SOAPMessageContext messageContext) {
        log(messageContext);
        return true;
    }

    private void log(SOAPMessageContext messageContext) {
        String xml = "";
        SOAPMessage msg = messageContext.getMessage();
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        try {
            msg.writeTo(out);
            xml = out.toString("UTF-8");
        } catch (Exception e) {
            log.error(e.getMessage(),e);
        }       

        String direction = "";
        Boolean outbound = (Boolean) messageContext.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY); 
        if (outbound) { 
            direction += "Request: \n"; 
        } else { 
            direction += "Response: \n";
        } 

        log.info(direction + getXMLprettyPrinted(xml));     
    }

    @Override
    public Set<QName> getHeaders() {
        return Collections.emptySet();
    }


    public String getXMLprettyPrinted(String xml) {

        if (transformer == null || docBuilder == null)
            return xml;

        InputSource ipXML = new InputSource(new StringReader(xml));
        Document doc;

        try {
            doc = docBuilder.parse(ipXML);
            StringWriter stringWriter = new StringWriter();
            StreamResult streamResult = new StreamResult(stringWriter);
            DOMSource domSource = new DOMSource(doc);
            transformer.transform(domSource, streamResult);
            return stringWriter.toString();
        } catch (SAXException | IOException | TransformerException e) {
            log.error(e.getMessage(), e);
            return xml;
        }
    }
}

此外，我想在我的应用程序代码中重用原始 XML。因此，我必须将这些数据从 SOAPHandler 传输回我的客户端代码。如何做到这一点还不太明显。有关此问题的更多信息可以在本文中找到： 如何将附加字段与soapMessage一起发送到soap处理程序？
