使用HTTPConnection直接Post参数进行调用

URL url = new URL(surl);
            HttpURLConnection connection = (HttpURLConnection) url
                    .openConnection();
            SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddHHmmssSSS");
            connection.setDoOutput(true);
            connection.setRequestMethod("POST");
            connection.setDoInput(true);
            connection.setRequestProperty("Content-Type",
                    "text/xml; charset=utf-8");
            connection.setRequestProperty("SOAPAction",
                    "http://tempuri.org/AddMyToReadList");
            OutputStreamWriter out = new OutputStreamWriter(
                    connection.getOutputStream(), "utf-8");
            StringBuilder sb = new StringBuilder();
sb.append("<MyToReadListInfo>");
                    sb.append("<SSIC_ID>" + info.getSsic_id() + "</SSIC_ID>");
                    sb.append("<URL><![CDATA[" + retURL + "]]></URL>");
                    sb.append("<OutID><![CDATA[" + strNow + "]]></OutID>");
                    sb.append("<Infor_Id><![CDATA[" + strNow.substring(8)
                            + "]]></Infor_Id>");
                    sb.append("<Stru_ID></Stru_ID>");
                    sb.append("<Opertor>000000003</Opertor>");
                    sb.append("<Status>0</Status>");
                    sb.append("<Title><![CDATA[" + strtitle + "]]></Title>");
                    sb.append("</MyToReadListInfo>");
StringBuilder header_sb = new StringBuilder();
                StringBuilder footer_sb = new StringBuilder();
                header_sb.append("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
                header_sb
                        .append("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">");
                header_sb.append("<soap:Body>");
                header_sb
                        .append("<AddMyToReadList xmlns=\"http://tempuri.org/\">");
                header_sb.append("<AppKeyValue>");
                header_sb.append("<AppID><![CDATA[" + getProperty("appid")
                        + "]]></AppID>");
                header_sb.append("<AppValue><![CDATA["
                        + getProperty("appvalue") + "]]></AppValue>");
                header_sb.append("</AppKeyValue>");
                header_sb.append("<MyToReadListInfoList>");
                footer_sb.append("</MyToReadListInfoList>");
                footer_sb.append("</AddMyToReadList>");
                footer_sb.append("</soap:Body>");
                footer_sb.append("</soap:Envelope>");
                out.write(header_sb.toString() + sb.toString() + footer_sb); // 直接post的进行调用！
//解析返回的XML字串
out.flush();
                out.close();
                connection.connect();
                InputStream urlStream = connection.getInputStream();
                BufferedReader bufferedReader = new BufferedReader(
                        new InputStreamReader(urlStream));
                String ss = null;
                String total = "";
                while ((ss = bufferedReader.readLine()) != null) {
                    total += ss;
                }
                logger.info("接口返回结果");
                logger.info(total);
                bufferedReader.close();
                Document document = DocumentHelper.parseText(total);
                Node node = document
                        .selectSingleNode("/soap:Envelope/soap:Body/*[name()='AddMyToReadListResponse']/*[name()='AddMyToReadListResult']/*[name()='RetCode']");
                String retCode = node.getText();
                logger.info("retCode = " + retCode);

可以使用XPath来直接读取解析返回的字串，具体路径如果无法准确获知，可通过下面的方法获取节点路径。

public static void treeWalk(Document document) {
        treeWalk(document.getRootElement());
    }
    public static void treeWalk(Element element) {
        for (int i = 0, size = element.nodeCount(); i < size; i++) {
            Node node = element.node(i);
            System.out.println("Name = " + element.getName() + " Path = "
                    + element.getPath());
            if (node instanceof Element) {
                treeWalk((Element) node);
            } else {
                // do something....
            }
        }
    }
