18.11. 如何以 PAYLOAD 数据格式处理 camel-cxf 端点的消息

PAYLOAD 意味着您将 SOAP envelope 中的有效负载作为原生 CxfPayload 处理。message .getBody （） 将返回 org.apache.camel.component.cxf.CxfPayload 对象，其中包含 SOAP 消息标头和 SOAP 正文的 getters。

请参阅 CxfConsumerPayloadTest ：

protected RouteBuilder createRouteBuilder() {
    return new RouteBuilder() {
        public void configure() {
            from(simpleEndpointURI + "&dataFormat=PAYLOAD").to("log:info").process(new Processor() {
                @SuppressWarnings("unchecked")
                public void process(final Exchange exchange) throws Exception {
                    CxfPayload<SoapHeader> requestPayload = exchange.getIn().getBody(CxfPayload.class);
                    List<Source> inElements = requestPayload.getBodySources();
                    List<Source> outElements = new ArrayList<>();
                    // You can use a customer toStringConverter to turn a CxfPayLoad message into String as you want
                    String request = exchange.getIn().getBody(String.class);
                    XmlConverter converter = new XmlConverter();
                    String documentString = ECHO_RESPONSE;

                    Element in = new XmlConverter().toDOMElement(inElements.get(0));
                    // Just check the element namespace
                    if (!in.getNamespaceURI().equals(ELEMENT_NAMESPACE)) {
                        throw new IllegalArgumentException("Wrong element namespace");
                    }
                    if (in.getLocalName().equals("echoBoolean")) {
                        documentString = ECHO_BOOLEAN_RESPONSE;
                        checkRequest("ECHO_BOOLEAN_REQUEST", request);
                    } else {
                        documentString = ECHO_RESPONSE;
                        checkRequest("ECHO_REQUEST", request);
                    }
                    Document outDocument = converter.toDOMDocument(documentString, exchange);
                    outElements.add(new DOMSource(outDocument.getDocumentElement()));
                    // set the payload header with null
                    CxfPayload<SoapHeader> responsePayload = new CxfPayload<>(null, outElements, null);
                    exchange.getMessage().setBody(responsePayload);
                }
            });
        }
    };
}
