校验汉字：

        Pattern pattern=Pattern.compile("^[Α-￥]+$");
        String name="陈";
        Matcher matcher = pattern.matcher(name);
        boolean matches = matcher.matches();
        System.out.println(matches);

校验url：

        Pattern pattern=Pattern.compile("^((http|https)://)([\\w-]+\\.)+[\\w-]+((:)(\\d)+)?(/[\\w-?=&/%.#]*)?$");

//        String url="https://192.168.216.98:45000/#/";
        String url="https://192.168.216.98:98:45000/#/";//false
        Matcher matcher = pattern.matcher(url);
        boolean matches = matcher.matches();
        System.out.println(matches);

校验电话号码：

        Pattern pattern = Pattern.compile("^1[3|4|5|8]\\d{9}");//或者 ^1[3|8][0-9]{9}
        String phone="13111111112";
        Matcher matcher = pattern.matcher(phone);
        boolean matches = matcher.matches();
        System.out.println(matches);

校验邮件：

        Pattern pattern = Pattern.compile("[a-zA-Z0-9]+@[a-zA-Z0-9]+(\\.[a-zA-Z0-9]+){1,2}");
        String email="aaa@qq.com.cn";
        Matcher matcher = pattern.matcher(email);
        boolean matches = matcher.matches();
        System.out.println(matches);
