Spring Integration Webservices

Question

我在spring集成时非常新，我正在尝试将以下代码转换为spring集成代码，但我无法正确发送请求。 我真的不知道自己做错了什么，做什么，实际上任务是拆分发送到webservices的XML，然后从中获取响应，然后聚合使其成为一个XML。 普通代码：

connection = (HttpURLConnection) validateServer.openConnection();
                connection.setRequestMethod("POST");
                connection.setDoInput(true);
                connection.setDoOutput(true);
                String parameters = "";
                if (isMultipleVal) {
                    parameters = ADD_FUNCTION2
                            + URLEncoder.encode(getxmldatalist, "UTF-8");
                } else {
                    parameters = ADD_FUNCTION
                            + URLEncoder.encode(getxmldatalist, "UTF-8");
                }
                LOG.info("parameters:" + parameters);
                System.out.println("In client parameters "+parameters);
                byte[] parameterAsBytes = parameters.getBytes();

                System.out.println("Parameters as bytes "+parameterAsBytes);
                connection.setRequestProperty(CONTENT_LENGTH,String.valueOf(parameterAsBytes.length));

                OutputStream oStream = connection.getOutputStream();
                oStream.write(parameterAsBytes, 0, parameterAsBytes.length);
                oStream.flush();
                oStream.close();
