16.16. 如何传播 camel-cxf 端点的请求和响应上下文

CXF 客户端 API 提供了一种通过请求和响应上下文调用操作的方法。如果您使用 camel-cxf 端点制作者调用外部 web 服务，您可以使用以下代码设置请求上下文并获取响应上下文：

        CxfExchange exchange = (CxfExchange)template.send(getJaxwsEndpointUri(), new Processor() {
             public void process(final Exchange exchange) {
                 final List<String> params = new ArrayList<String>();
                 params.add(TEST_MESSAGE);
                 // Set the request context to the inMessage
                 Map<String, Object> requestContext = new HashMap<String, Object>();
                 requestContext.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, JAXWS_SERVER_ADDRESS);
                 exchange.getIn().setBody(params);
                 exchange.getIn().setHeader(Client.REQUEST_CONTEXT , requestContext);
                 exchange.getIn().setHeader(CxfConstants.OPERATION_NAME, GREET_ME_OPERATION);
             }
         });
         org.apache.camel.Message out = exchange.getOut();
         // The output is an object array, the first element of the array is the return value
         Object\[\] output = out.getBody(Object\[\].class);
         LOG.info("Received output text: " + output\[0\]);
         // Get the response context form outMessage
         Map<String, Object> responseContext = CastUtils.cast((Map)out.getHeader(Client.RESPONSE_CONTEXT));
         assertNotNull(responseContext);
         assertEquals("Get the wrong wsdl operation name", "{http://apache.org/hello_world_soap_http}greetMe",
                      responseContext.get("javax.xml.ws.wsdl.operation").toString());
