Spring MVC Internationalization (i18n) ve Localization (L10n) \u00d6rne\u011fi<\/h2>\n
Spring Framework, modern web uygulamalar\u0131n\u0131n geli\u015ftirilmesinde en \u00e7ok tercih edilen ekosistemlerden biridir. G\u00fcn\u00fcm\u00fcz k\u00fcresel d\u00fcnyas\u0131nda, bir uygulaman\u0131n farkl\u0131 dilleri ve k\u00fclt\u00fcrel tercihleri desteklemesi, kullan\u0131c\u0131 deneyimi a\u00e7\u0131s\u0131ndan kritik bir \u00f6neme sahiptir. Bu makale, Spring MVC tabanl\u0131 uygulamalarda uluslararas\u0131la\u015ft\u0131rma (Internationalization – i18n) ve yerelle\u015ftirme (Localization – L10n) kavramlar\u0131n\u0131, bunlar\u0131n nas\u0131l uyguland\u0131\u011f\u0131n\u0131 ve ad\u0131m ad\u0131m bir \u00f6rnekle nas\u0131l hayata ge\u00e7irilece\u011fini detayl\u0131 bir \u015fekilde ele alacakt\u0131r.<\/p>\n

Giri\u015f: K\u00fcreselle\u015fen D\u00fcnyada Uygulama Geli\u015ftirme<\/h3>\n
Uygulamalar\u0131m\u0131z\u0131 geli\u015ftirirken, genellikle hedef kitlemizin tek bir dil veya b\u00f6lge ile s\u0131n\u0131rl\u0131 olmad\u0131\u011f\u0131n\u0131 fark ederiz. Bir uygulaman\u0131n d\u00fcnya \u00e7ap\u0131nda ba\u015far\u0131l\u0131 olabilmesi i\u00e7in farkl\u0131 dilleri, para birimlerini, tarih formatlar\u0131n\u0131 ve k\u00fclt\u00fcrel normlar\u0131 desteklemesi gerekir. \u0130\u015fte tam bu noktada i18n ve L10n devreye girer.<\/p>\n
Uluslararas\u0131la\u015ft\u0131rma (i18n), bir uygulaman\u0131n farkl\u0131 diller ve b\u00f6lgeler i\u00e7in uyarlanabilir hale getirilmesi s\u00fcrecidir. Bu, uygulaman\u0131n kod taban\u0131nda dil veya b\u00f6lgeye \u00f6zel metinlerin, formatlar\u0131n veya di\u011fer k\u00fclt\u00fcrel unsurlar\u0131n sabit kodlanmamas\u0131 anlam\u0131na gelir. “i18n” terimi, “internationalization” kelimesindeki ‘i’ ve ‘n’ harfleri aras\u0131nda 18 harf bulunmas\u0131ndan gelir.<\/p>\n
Yerelle\u015ftirme (L10n) ise, uluslararas\u0131la\u015ft\u0131r\u0131lm\u0131\u015f bir uygulaman\u0131n belirli bir dil ve b\u00f6lgeye \u00f6zel hale getirilmesi s\u00fcrecidir. Bu s\u00fcre\u00e7, metinlerin \u00e7evrilmesini, tarih ve saat formatlar\u0131n\u0131n ayarlanmas\u0131n\u0131, para birimi sembollerinin ve bi\u00e7imlerinin d\u00fczenlenmesini, renklerin, g\u00f6rsellerin ve di\u011fer k\u00fclt\u00fcrel unsurlar\u0131n hedeflenen b\u00f6lgeye uygun hale getirilmesini i\u00e7erir. “L10n” terimi de “localization” kelimesindeki ‘L’ ve ‘n’ harfleri aras\u0131nda 10 harf bulunmas\u0131ndan t\u00fcretilmi\u015ftir.<\/p>\n
Spring Framework, bu karma\u015f\u0131k s\u00fcre\u00e7leri basitle\u015ftirmek ve geli\u015ftiricilere g\u00fc\u00e7l\u00fc ara\u00e7lar sunmak i\u00e7in tasarlanm\u0131\u015ft\u0131r. Spring MVC’nin i18n ve L10n deste\u011fi sayesinde, uygulamalar\u0131n\u0131z\u0131 kolayca \u00e7ok dilli ve \u00e7ok b\u00f6lgeli hale getirebilirsiniz.<\/p>\n

Temel Kavramlar ve Spring Mekanizmalar\u0131<\/h3>\n
Spring MVC’de i18n ve L10n’yi anlamak i\u00e7in baz\u0131 temel kavramlar\u0131 ve Spring’in bu konudaki ana bile\u015fenlerini bilmek \u00f6nemlidir.<\/p>\n

Locale (Yerel Ayarlar)<\/h4>\n
java.util.Locale<\/code> s\u0131n\u0131f\u0131, belirli bir co\u011frafi, politik veya k\u00fclt\u00fcrel b\u00f6lgeyi temsil eder. Bir Locale<\/code>, genellikle bir dil kodu (\u00f6rn. en<\/code> for English, tr<\/code> for Turkish) ve iste\u011fe ba\u011fl\u0131 olarak bir \u00fclke kodu (\u00f6rn. US<\/code> for United States, TR<\/code> for Turkey) kombinasyonundan olu\u015fur. \u00d6rne\u011fin, en_US<\/code> Amerika Birle\u015fik Devletleri \u0130ngilizcesi’ni, tr_TR<\/code> T\u00fcrkiye T\u00fcrk\u00e7esi’ni temsil eder. Spring, kullan\u0131c\u0131n\u0131n tercih etti\u011fi Locale<\/code>‘i belirleyerek ve bu Locale<\/code>‘e g\u00f6re i\u00e7erik sunarak i18n’yi y\u00f6netir.<\/p>\n

Resource Bundles (Kaynak Paketleri \/ Mesaj Paketleri)<\/h4>\nResource Bundles, farkl\u0131 dillerdeki metin mesajlar\u0131n\u0131, etiketleri ve di\u011fer yerelle\u015ftirilmi\u015f i\u00e7eri\u011fi depolamak i\u00e7in kullan\u0131lan dosyalard\u0131r. Spring’de bu genellikle .properties<\/code> uzant\u0131l\u0131 dosyalard\u0131r. Her dil ve b\u00f6lge kombinasyonu i\u00e7in ayr\u0131 bir .properties<\/code> dosyas\u0131 olu\u015fturulur.<\/p>\n

Spring’in en yayg\u0131n MessageSource<\/code> implementasyonlar\u0131 \u015funlard\u0131r:
\n*   ResourceBundleMessageSource<\/code>: Sabit bir dizindeki .properties<\/code> dosyalar\u0131ndan mesajlar\u0131 y\u00fckler. Uygulama ba\u015flat\u0131ld\u0131\u011f\u0131nda t\u00fcm mesajlar\u0131 y\u00fckler ve \u00f6nbelle\u011fe al\u0131r.

Spring, \u00e7e\u015fitli LocaleResolver<\/code> implementasyonlar\u0131 sunar:<\/p>\n

\n*   SessionLocaleResolver<\/code>: Kullan\u0131c\u0131n\u0131n Locale<\/code>‘ini HTTP oturumunda (session) saklar. Kullan\u0131c\u0131 bir kez dil se\u00e7ti\u011finde, bu tercih oturum boyunca korunur.
\n*   CookieLocaleResolver<\/code>: Kullan\u0131c\u0131n\u0131n Locale<\/code>‘ini bir HTTP \u00e7erezinde (cookie) saklar. Bu, kullan\u0131c\u0131n\u0131n tercihini oturumlar aras\u0131nda bile hat\u0131rlamak i\u00e7in idealdir.
\n*   FixedLocaleResolver<\/code>: Her zaman sabit bir Locale<\/code> d\u00f6nd\u00fcr\u00fcr. Genellikle test ama\u00e7l\u0131 veya tek dilli uygulamalar i\u00e7in kullan\u0131l\u0131r.<\/p>\n
LocaleChangeInterceptor (Yerel Ayar De\u011fi\u015fim Yakalay\u0131c\u0131s\u0131)<\/h4>\norg.springframework.web.servlet.i18n.LocaleChangeInterceptor<\/code>, kullan\u0131c\u0131n\u0131n URL parametresi (\u00f6rn. ?lang=tr<\/code>) veya ba\u015fka bir yolla Locale<\/code>‘ini de\u011fi\u015ftirmesine olanak tan\u0131r.
