java中驗證國際手機号碼

最近有QA的同僚回報需要在背景驗證手機号碼的有效性，由于項目的國際化，是以用簡單的正規表達式很難實作，最後發現采用谷歌的libphonenumber可以很好地的很友善的實作。

首先我們需要引入如下幾個包

compile('com.googlecode.libphonenumber:geocoder:2.104')
    compile('com.googlecode.libphonenumber:libphonenumber:8.9.15')
    compile('com.googlecode.libphonenumber:carrier:1.94')
    compile('com.googlecode.libphonenumber:prefixmapper:2.104')
           

添加依賴包以後我們就可以很友善實作以下驗證代碼：

import com.google.i18n.phonenumbers.NumberParseException;
import com.google.i18n.phonenumbers.PhoneNumberToCarrierMapper;
import com.google.i18n.phonenumbers.PhoneNumberUtil;
import com.google.i18n.phonenumbers.Phonenumber;
import com.google.i18n.phonenumbers.geocoding.PhoneNumberOfflineGeocoder;

/**

public class PhoneUtil {
    private static PhoneNumberUtil phoneNumberUtil = PhoneNumberUtil.getInstance();

    private static PhoneNumberToCarrierMapper carrierMapper = PhoneNumberToCarrierMapper.getInstance();

    private static PhoneNumberOfflineGeocoder geocoder = PhoneNumberOfflineGeocoder.getInstance();

    /**
     * check phone
     *
     * @param phoneNumber eg" 18012345678"
     * @param countryCode eg "86"
     * @return the result "true" or "false"
     */
    public static boolean checkPhoneNumber(String phoneNumber, Integer countryCode) {

        long phone = Long.parseLong(phoneNumber);

        Phonenumber.PhoneNumber pn = new Phonenumber.PhoneNumber();
        pn.setCountryCode(countryCode);
        pn.setNationalNumber(phone);

        return phoneNumberUtil.isValidNumber(pn);
    }

    /**
     * check phone that it brings country code
     *
     * @param phoneNumber eg" [phone]"
     * @return the result "true" or "false"
     * @throws NumberParseException handle phone that it can't resolve
     */
    public static boolean checkPhoneNumberBringCountryCode(String phoneNumber) throws NumberParseException {
        Phonenumber.PhoneNumber cn = phoneNumberUtil.parse(phoneNumber, "CN");
        return phoneNumberUtil.isValidNumber(cn);
    }
}
           

上述兩個方法分别可檢驗含有國際代碼的手機号和普通的傳入電話号碼、國家代碼的驗證，如需判斷營運商和手機号碼的歸屬地，可采用以下方法：

/**
     * 根據國家代碼和手機号  判斷手機營運商
     * @date 2017-4-26 上午11:30:18
     * @param phoneNumber
     * @param countryCode
     * @return
     */
    public static String getCarrier(String phoneNumber, Integer countryCode){
 
        long phone = Long.parseLong(phoneNumber);
 
        PhoneNumber pn = new PhoneNumber();
        pn.setCountryCode(countryCode);
        pn.setNationalNumber(phone);
        //傳回結果隻有英文，自己轉成成中文
        String carrierEn = carrierMapper.getNameForNumber(pn, Locale.ENGLISH);
        String carrierZh = "";
        carrierZh += geocoder.getDescriptionForNumber(pn, Locale.CHINESE);
        switch (carrierEn) {
        case "China Mobile":
            carrierZh += "移動";
            break;
        case "China Unicom":
            carrierZh += "聯通";
            break;
        case "China Telecom":
            carrierZh += "電信";
            break;
        default:
            break;
        }
        return carrierZh;
    }
 
 
    /**

    * @param phoneNumber
    * @param countryCode
    * @return    參數
     */
    public static String getGeo(String phoneNumber, Integer countryCode){
 
        long phone = Long.parseLong(phoneNumber);
 
        PhoneNumber pn = new PhoneNumber();
        pn.setCountryCode(countryCode);
        pn.setNationalNumber(phone);
 
        return geocoder.getDescriptionForNumber(pn, Locale.CHINESE);
