public void sendSMS(ModelMap map,HttpServletRequest request,HttpServletResponse response, @RequestParam String phone) throws NumberFormatException,Exception{ 
        组装参数：
        String url = "http://sdk2.entinfo.cn:8061/mdsmssend.ashx?"; //发送地址
        String sn = "SDK-HFY-010-00024";      //sn
        String pwd = "28728CB1AD539A991E7CB6BA91B349C7";    //sn密码

        String falg = "0";//失败
        String info = "";
        String msgCode = CreateRandom.createRandom(true, 6);    //生成验证码工具类
        String smsContent = "您好，尊敬的会员：您本次操作的验证码为："+msgCode+",请及时验证！【金融猫大学生分期商城】";

       
        try {
      调用发送方法：
            SendMessageUtil.sendSMS(url, sn, pwd, phone, smsContent, request, response);
            falg = "1";
            info = "短信发送成功";
        } catch (Exception e)  {
            e.printStackTrace();
            info = "短信发送失败,请重新发送";
        }
       
        request.getSession().setAttribute("msgCode", msgCode);//session绑定验证码用于提交时的对比验证
       组装响应数据：
        Map<String, Object> codeMsgMap = new HashMap<String, Object>();
        codeMsgMap.put("status", falg);
        codeMsgMap.put("info", info);
        codeMsgMap.put("data", "");
        this.out(response, codeMsgMap);//调用输出方法
}

 

发送方法：

  response.setContentType("text/html;charset=UTF-8");
  content = URLEncoder.encode(content,"utf-8");
  String smsUrl = url+"sn="+sn+"&pwd="+pwd+"&mobile="+mobile+"&content="+content;//组装发送短信的完整数据
  URL getUrl;
  try { //准备
   getUrl = new URL(smsUrl);
   HttpURLConnection connection = (HttpURLConnection) getUrl.openConnection();
          
     // 建立与服务器的连接，并未发送数据
            connection.connect();

            // 发送数据到服务器并使用Reader读取返回的数据
            BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            String lines;
            while ((lines = reader.readLine()) != null) {
                 System.out.println(lines);

        GsonBuilder gbuild = new GsonBuilder();
        try {
            response.setContentType("text/javascript;charset=UTF-8");
            PrintWriter out = response.getWriter();
