21.8.5 地区更改拦截器LocaleChangeInterceptor
You can enable changing of locales by adding the LocaleChangeInterceptor
to
one of the handler mappings (see [Section 21.4, “Handler mappings”]($publish-21-8-mvc.html
mvc-handlermapping “21.4 Handler mappings” )). It will detect a parameter in
the request and change the locale. It calls setLocale()
on the
LocaleResolver
that also exists in the context. The following example shows
that calls to all *.view
resources containing a parameter named
siteLanguage
will now change the locale. So, for example, a request for the
following URL, <http://www.sf.net/home.view?siteLanguage=nl>
will change the
site language to Dutch.
你可以在处理器映射(详见21.4 处理器映射(Handler mappings)小节)前添加一个LocaleChangeInterceptor
拦截器来更改地区信息。它能检测请求中的参数,并根据其值相应地更新地区信息。它通过调用LocaleResolver
的setLocale()
方法来更改地区。下面的代码配置展示了如何为所有请求*.view
路径并且携带了siteLanguage
参数的资源请求更改地区。举个例子,一个URL为<http://www.sf.net/home.view?siteLanguage=nl>
的请求将会将站点语言更改为荷兰语。
