 /**
     * 正则表达式匹配两个指定字符串中间的内容

    public static List<String> getSubUtil(String soap, String rgex){

        Pattern pattern = Pattern.compile(rgex);// 匹配的模式
        Matcher m = pattern.matcher(soap);

    }
        ==========================

           String regs = ""actId":"(\d+)"";
        List<String> subUtil = getSubUtil(s, regs);
        System.out.println(subUtil);
