Java sends and parses Soap Xml data

Recently, a project encountered a customer Soap system that needed to be connected. Checking their C# source code found that the format is as follows, which is not the same as the Xml data used before, so I studied how to package it.

 request data

                String sendMsg="<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" +
                    "<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/\">\n" +
                    "  <soap:Body>\n" +
                    "    <GetUserInfo xmlns=\"http://tempuri.org/\">\n" +
                    "      <code>103431</code>\n" +
                    "      <pwd>19</pwd>\n" +
                    "    </GetUserInfo>\n" +
                    "  </soap:Body>\n" +
                    "</soap:Envelope>";

request method

    /**
     * 拼接请求体
     * @param table 表面
     * @param fields 参数键值对 name:key value:value
     * @return 拼接后xml
     */
    public static String requestWeb(String table, Map<String, String> fields) {
        String fieldsMsg = "";
        for (Map.Entry<String, String> entry : fields.entrySet()) {
            fieldsMsg += "<" + entry.getKey() + ">" + entry.getValue() + "</" + entry.getKey() + ">";
        }
        String sendMsg = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" +
                "<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/\">\n" +
                "  <soap:Body>\n" +
                "    <" + table + " xmlns=\"http://tempuri.org/\">\n" +
                fieldsMsg +
                "    </" + table + ">\n" +
                "  </soap:Body>\n" +
                "</soap:Envelope>";
        return sendMsg;
    }


            //表名
            String table="GetUserInfo";
            Map<String, String> fields = new HashMap<>();
            //参数
            fields.put("code", username);
            fields.put("pwd", password);
            String sendMsg = SoapUtils.requestWeb(table, fields);
//发送请求时需要加上.mediaType(MediaType.parse("text/xml; charset=utf-8"))

 Parse data using dom4j

There are two data formats, single data (such as obtaining user information), and list data (acquiring document information)

    /**
     * 解析SOAP返回数据
     * @param response 数据源
     * @param table 表名
     * @return Map;空数据返回null
     * 单数据形式

     *     <XXResult>
     *         <ID></ID>
     *         <NAME></NAME>
     *     </XXResult>
     * </XXResponse>
