 /**
* 从字符串中查找数字字符串
*/
private List<String> getNumbers(String content) {
    List<String> digitList = new ArrayList<String>();
    Pattern p = Pattern.compile("(\\d+)");
    Matcher m = p.matcher(content);
    while (m.find()) {
      String find = m.group(1).toString();
      digitList.add(find);
    }
    return digitList;
}
