Java验证手机号

在实际开发中我们需要对手机号格式校验，以下是对中国手机号校验的实现。

public class PhoneUtils {
	/**
	 * 中国手机号码
	 */
	private static Pattern CHINESE_PHONE_PATTERN = Pattern.compile("((13|15|17|18)\\d{9})|(14[57]\\d{8})");
	/**
	 * 是否是有效的中国手机号码
	 * @param phone
	 * @return
	 */
	public static boolean isValidChinesePhone(String phone) {
		if (phone == null || phone.length() != 11) {
			return false;
		}
		Matcher matcher = CHINESE_PHONE_PATTERN.matcher(phone);
		return matcher.matches();
	}
	/**
	 * 检查手机是否无效
	 * @param phone
	 * @return
	 */
	public static boolean isNotValidChinesePhone(String phone) {
		return !isValidChinesePhone(phone);
	}
	/**
	 * 手机中间添加星号
	 * @param phone
	 * @param beginIndex
	 * @param endIndex
	 * @return empty string if phone length is illegal
	 */
	public static String setAsterisk(String phone, int beginIndex, int endIndex) {
		if (StringUtils.isBlank(phone)) {
			return StringUtils.EMPTY;
		}
		if (beginIndex < 0 || endIndex < 0 || beginIndex > phone.length() || endIndex > phone.length()) {
			throw new IllegalArgumentException("illegal index " + beginIndex + "," + endIndex);
		}
        StringBuilder phoneWithAsterisk = new StringBuilder(phone.substring(0, beginIndex));  
        for (int i = beginIndex; i < endIndex; i++) {
        	phoneWithAsterisk.append("*");
        }  
        phoneWithAsterisk.append(phone.substring(endIndex, phone.length()));
		return phoneWithAsterisk.toString();
	}
	/**
	 * 手机中间添加星号
	 * @param phone
	 * @return
	 */
	public static String setAsterisk(String phone) {
		return setAsterisk(phone, 3, 7);
	}
	/**
	 * 手机中间添加星号,中间六位
	 * @param phone
	 * @return
	 */
	public static String setAsterisk2(String phone) {
		return setAsterisk(phone, 3, 9);
	}
}
