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());
	}
	...
}
