Javaで電話番号フォーマット

なんだよーこいつもすげーらくじゃーん

<dependency>
    <groupId>com.googlecode.libphonenumber</groupId>
    <artifactId>libphonenumber</artifactId>
    <version>3.6</version>
</dependency>

String tel = "0451234567";
Phonenumber.PhoneNumber phoneNumber = PHONE_NUMBER_UTIL.parse(tel, "JP");
tel = PHONE_NUMBER_UTIL.format(phoneNumber, PhoneNumberUtil.PhoneNumberFormat.NATIONAL);
System.out.println(tel);

045-123-4567

になるぜ。

SpringのCustomEditor使ってこんな風にもねぇ。

public class PhoneNumberEditor extends PropertyEditorSupport {

    private static final PhoneNumberUtil PHONE_NUMBER_UTIL = PhoneNumberUtil.getInstance();

    @Override
    public void setAsText(String text) {
        if (!StringUtils.hasText(text)) {
            setValue(null);
        }
        else {
            try {
                Phonenumber.PhoneNumber phoneNumber = PHONE_NUMBER_UTIL.parse(text, "JP");
                text = PHONE_NUMBER_UTIL.format(phoneNumber, PhoneNumberUtil.PhoneNumberFormat.NATIONAL);
            }
            catch (NumberParseException e) {
                // Do Nothing
            }
            setValue(text);
        }
    }
}

@Controller
@RequestMapping(value="/hoge")
public class HogeController {

    @InitBinder(FORM_MODEL_KEY)
    public void initBinder(WebDataBinder binder, HttpServletRequest request) {
        binder.registerCustomEditor(String.class, "tel", new PostalCodeEditor());
    }
    ...
}
