        String regex = "(http:|https:)//[^[A-Za-z0-9\\._\\?%&+\\-=/#]]*";
        Pattern pattern = Pattern.compile(regex);
        Matcher matcher = pattern.matcher(str);
        StringBuffer result = new StringBuffer();
        while (matcher.find()) {
            StringBuffer replace = new StringBuffer();
            replace.append("<a href=\"").append(matcher.group());
            replace.append("\" target=\"_blank\">点击打开链接</a>");
            matcher.appendReplacement(result, replace.toString());
        }
        matcher.appendTail(result);
        System.out.println(str);
        System.out.println(result);
