  /**
     * 替换模板标签变量
     *
     * @param params        变量键值
     * @param templetConent 模板内容
     * @return
     */
    public String replaceTempletTags(SmsParams params, String templetConent) {
        String smsContent;
        try {
            //生成匹配模式的正则表达式
            String patternString = "\\$\\{(" + StringUtils.join(params.getSmsParam().keySet(), "|") + ")\\}";

            Pattern pattern = Pattern.compile(patternString);
            Matcher matcher = pattern.matcher(templetConent);

            //两个方法：appendReplacement, appendTail
            StringBuffer sb = new StringBuffer();
            while (matcher.find()) {
                matcher.appendReplacement(sb, params.getSmsParam().get(matcher.group(1)).toString());
            }
            matcher.appendTail(sb);
            smsContent = sb.toString();
        } catch (Exception e) {
            throw new RuntimeException("解析模板并替换标签值时失败！" + e);
        }
        return smsContent;
