Spring MVC 了解地區(qū)更改攔截器

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 namedsiteLanguage 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.

你可以在處理器映射（詳見Spring MVC 處理器映射小節(jié)）前添加一個LocaleChangeInterceptor攔截器來更改地區(qū)信息。它能檢測請求中的參數(shù)，并根據(jù)其值相應(yīng)地更新地區(qū)信息。它通過調(diào)用LocaleResolver的setLocale()方法來更改地區(qū)。下面的代碼配置展示了如何為所有請求*.view路徑并且攜帶了siteLanguage參數(shù)的資源請求更改地區(qū)。舉個例子，一個URL為<http://www.sf.net/home.view?siteLanguage=nl>的請求將會將站點語言更改為荷蘭語。
