Java提取文本中的超链接添加a标签

项目有个需求，前端直接复制一段文字到富文本编辑器，其中可能包含若干个url，在后台需要找到文字中的url加上a标签，方便展示的时候可以直接让用户点击。找了很久，直接上代码。

     //处理超链接//message为需要处理的字符串String msg = message;Matcher matcher = Patterns.WEB_URL.matcher(message);List<String> urls = new ArrayList<>();while (matcher.find()) {String url = matcher.group();urls.add(url);message = message.replace(url, "");matcher = Patterns.WEB_URL.matcher(message);}for (String url : urls) {msg = msg.replace(url, "<a target='_blank' href='http://" + url + "'>" + url + "</a>");}message = msg;
