创建一个会话范围的托管 bean，如下所示:
Create a session scoped managed bean like follows:
@ManagedBean
@SessionScoped
public class LocaleManager {
private Locale locale;
@PostConstruct
public void init() {
locale = FacesContext.getCurrentInstance().getExternalContext().getRequestLocale();
}
public Locale getLocale() {
return locale;
}
public String getLanguage() {
return locale.getLanguage();
}
public void setLanguage(String language) {
locale = new Locale(language);
FacesContext.getCurrentInstance().getViewRoot().setLocale(locale);
}
}
要设置视图的当前语言环境，请将其绑定到主模板的 <f:view>.
To set the current locale of the views, bind it to the <f:view> of your master template.
<f:view locale="#{localeManager.locale}">
要更改它，请将其绑定到具有语言选项的 <h:selectOneMenu>.
To change it, bind it to a <h:selectOneMenu> with language options.
<h:form>
<h:selectOneMenu value="#{localeManager.language}" onchange="submit()">
<f:selectItem itemValue="en" itemLabel="English" />
<f:selectItem itemValue="nl" itemLabel="Nederlands" />
<f:selectItem itemValue="es" itemLabel="Español" />
</h:selectOneMenu>
</h:form>
要提高国际化页面的 SEO(否则会被标记为重复内容)，请将语言绑定到 <html>.
To improve SEO of your internationalized pages (otherwise it would be marked as duplicate content), bind language to <html> as well.
<html lang="#{localeManager.language}">
