1、时间格式化
Date date = new Date(); date.setTime(1345016039L * 1000); SimpleDateFormat dateformat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); System.out.println(dateformat.format(date))
2、正则表达式获取域名
private String getDomainFromUrl(String url) { Pattern p = Pattern.compile("(?<=//|)((\\w|-)+\\.)+\\w+", Pattern.CASE_INSENSITIVE); Matcher matcher = p.matcher(url); if (matcher.find()) { return matcher.group(0); } else { return ""; } }
