@RequestMapping("/sendMsg.mob")
@ResponseBody
public String sendMsg(HttpServletRequest request)  {
    ServletInputStream inputStream = null;
    String param = "";
    try {
        // 获取请求输入流
        inputStream = request.getInputStream();
        //将请求信息转换为字符串
        param = IOUtils.toString(inputStream, "UTF-8");
    } catch (IOException e2) {
        e2.printStackTrace();
