由于项目对标国际，简单的正则表达式很难覆盖全面国际手机号，谷歌的libphonenumber可以很好地的很方便的很全面的实现国际收集归属地验证。

使用libphonenumber

libphonenumber是一个工具包，不增加其他第三方依赖，直接引入依赖使用即可。

• 引入libphonenumber四个jar依赖

    <dependency>
      <groupId>com.googlecode.libphonenumber</groupId>
      <artifactId>libphonenumber</artifactId>
      <version>8.12.16</version>
    </dependency>

    <dependency>
      <groupId>com.googlecode.libphonenumber</groupId>
      <artifactId>geocoder</artifactId>
      <version>2.152</version>
    </dependency>

    <dependency>
      <groupId>com.googlecode.libphonenumber</groupId>
      <artifactId>carrier</artifactId>
      <version>1.142</version>
    </dependency>

    <dependency>
      <groupId>com.googlecode.libphonenumber</groupId>
      <artifactId>prefixmapper</artifactId>
      <version>2.152</version>
    </dependency>

• 使用libphonenumber工具包进行手机号处理

    resultObject.put("countryCode", countryCode);
    // 去掉+号 和 国号/区号 后的实际号码
    resultObject.put("nationalNumber", nationalNumber);
    // 所在地区描述信息
    resultObject.put("description", description);
    // 去掉+号后的号码 (用于阿里云发送短信)
    resultObject.put("number", String.valueOf(countryCode) + nationalNumber);

  }

    } catch (Exception e) {

使用效果

{"number":"12843418176","regionCode":"VG","nationalNumber":2843418176,"countryCode":1,"description":"英属维京群岛","fullNumber":"+1-2843418176)"}

• ps 经验证的手机号格式应该满足 “+国际区号手机号”格式，才能正确获取到手机号信息
