使用Apache Camel和Apache CXF进行Soap Web服务

Question

I am implementing SOAP web services with Apache CXF. I am using Jboss EAP server. I have used following code to expose SOAP web services.

CxfComponent cxfComponent = new CxfComponent(context);
            CxfEndpoint serviceEndpoint = new CxfEndpoint(FPSoapServiceConstants.WSDL_CONFIG_URI, cxfComponent);
            serviceEndpoint.setDataFormat(DataFormat.PAYLOAD);
        serviceEndpoint.setServiceClass(com.fp.en.webservices.fulfillment.FulfillmentService.class);
        HashMap<String, Object> properties = new HashMap<>();
        properties.put("faultStackTraceEnabled", true);
        properties.put("exceptionMessageCauseEnabled", true);
        serviceEndpoint.configureProperties(properties);
        serviceEndpoint.setLoggingFeatureEnabled(true);
        context.addEndpoint(FPSoapServiceConstants.SOAP_ENDPOINT_FULFILLMENT_SERVICE, serviceEndpoint);

I am using apache camel to process incoming soap message

route.process(fpSOAPRequestProcessor).process(xyzProcessor).process(fpSOAPResponseProcessor)

I want to get all parameters in an object I created a class and try to get body

BuyProductRequest buyRequest = message.getBody(BuyProductRequest.class);

but this is giving me null. But when I try to get

String buyRequest = message.getBody(String.class);

It is giving me SOAP message So I have to convert xml SOAP message to Object by JAXB Marshaller. Processor code is as follows

public class FPSoapRequestProcessor implements Processor{

    @Override
    public void process(Exchange exchange) throws Exception {
        Message message = exchange.getIn();
        String operation = String.valueOf(exchange.getIn().getHeader("operationName"));
        if(FPSoapServiceConstants.BUY_PRODUCT_SOAP_OPERATION.equalsIgnoreCase(operation)) {
            populateBuyProductOperationProperties(message);
        }


    }

    private void populateBuyProductOperationProperties(Message message) {
        String buyRequest = message.getBody(String.class);
        BuyProductRequest productInfo= parseRequest(buyRequest);
        message.setHeader("MSISDN", productInfo.getMsisdn());
        message.setHeader("iname", productInfo.getIname());
        message.setHeader("input", productInfo.getInput());
        message.setHeader("username", productInfo.getUserName());
        message.setHeader("password", productInfo.getPassword());
        message.setHeader("soapConversion", true);

    }

    private BuyProductRequest parseRequest(String soapRequest){
        try(InputStream is = new ByteArrayInputStream(soapRequest.getBytes())) {
            JAXBContext jaxbContext = JAXBContext.newInstance(BuyProductRequest.class);
            Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
            return (BuyProductRequest) jaxbUnmarshaller.unmarshal(is);
        } catch (Exception e) {
            throw new RuntimeException("SOAP Request Object Resolving Error",e);
        }
    }


}

So Is there any simple way to construct request object and Similarly at that time when I am done with processing, in fpSOAPResponseProcessor I have to convert my object into soap string then I am sending it.

fpSoapResponseProcessor code is as follows

public class FDPSoapResponseProcessor implements Processor{
    @Override
    public void process(Exchange exchange) throws Exception {
        Message message = exchange.getIn();

        FulfillmentResponse response = XmlUtil.unmarshall(message.getBody(String.class), FulfillmentResponse.class);
        BuyProductResponse buyProductResponse = new BuyProductResponse();

        buyProductResponse.setProductResponse(response);
        String soapResponse = parse(buyProductResponse);

        exchange.getOut().setBody(soapResponse);

    }

    private String parse(BuyProductResponse buyProductResponse) {
        try(StringWriter writer = new StringWriter()){
            JAXBContext jContext = JAXBContext.newInstance(BuyProductResponse.class);
            Marshaller marshallObj = jContext.createMarshaller();
            marshallObj.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
            marshallObj.setProperty("com.sun.xml.bind.xmlDeclaration", Boolean.FALSE);
            marshallObj.setProperty(Marshaller.JAXB_ENCODING, "UTF-8");
            marshallObj.setProperty("com.sun.xml.bind.namespacePrefixMapper", new FulfillmentResponseMapper());
            marshallObj.marshal(buyProductResponse, writer);
            return writer.toString();
        } catch(Exception e) {
            throw new RuntimeException("SOAP Request String Parsing Error",e);
        }
    }

    private static class FulfillmentResponseMapper extends NamespacePrefixMapper {

        @Override
        public String getPreferredPrefix(String namespaceUri, String suggestion, boolean requirePrefix) {
            if(FPSoapServiceConstants.SOAP_NAMESPACE_URI.equalsIgnoreCase(namespaceUri)) {
                return FPSoapServiceConstants.SOAP_PREFIX;
            } 
            return suggestion;
        }

        @Override
        public String[] getPreDeclaredNamespaceUris() {
            return new String[] { FPSoapServiceConstants.SOAP_NAMESPACE_URI};
        }

    }



}

Please suggest a proper simple way If there is?

AFAICS，这是简单的方法。
