SpringMVC LocaleChangeInterceptor Sınıfı

Giriş

Şu satırı dahil ederiz

import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.i18n.SessionLocaleResolver;
import org.springframework.web.servlet.i18n.LocaleChangeInterceptor;

Açıklaması şöyle

Note: For SessionLocaleResolver and CookieLocaleResolver we need to have an interceptor to get the parameter sent from the user for the preferred language and store it in session or cookie. Thanks to spring this has been done already don and you can use LocaleChangeInterceptor and just pass the name of the property to set the locale.

Örnek

Şöyle yaparız.

@Bean
public LocaleResolver localeResolver() {
  return new SessionLocaleResolver();
}

@Bean
public LocaleChangeInterceptor localeChangeInterceptor() {
  return new LocaleChangeInterceptor();
}

@Override
public void addInterceptors(InterceptorRegistry registry) {
  registry.addInterceptor(localeChangeInterceptor());
}

Açıklaması şöyle

The LocaleChangeInterceptor looks for a request parameter name locale by default. If you are not interested to use that parameter, you can override it by giving your own parameter name.

Böylece kullanıcı farklı locale görmek isterse şöyle istekler gönderir
