Retrieve active locale in Grails application
提问by thomers
I know I can use the "lang" parameter to automatically change the current locale as described in the docs, but how do I track those changes, for example to update the language stored in the current user domain object?
我知道我可以使用“lang”参数来自动更改文档中描述的当前语言环境，但是如何跟踪这些更改，例如更新存储在当前用户域对象中的语言？
request.localedoes not work, since it does not reflect the changes done via "?lang=xx"
request.locale不起作用，因为它没有反映通过“ ?lang=xx”所做的更改

Within your controller you can obtain the locale using the RequestContextUtils.
在您的控制器中，您可以使用RequestContextUtils.
import org.springframework.web.servlet.support.RequestContextUtils as RCU
Then to resolve the locale for the request:
然后解析请求的语言环境：
RCU.getLocale(request)

Grails uses Spring internally. You can get the current locale from Spring's RequestContextUtils: http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/web/servlet/support/RequestContextUtils.html#getLocale(javax.servlet.http.HttpServletRequest)
Grails 在内部使用 Spring。您可以从 Spring 的 RequestContextUtils 获取当前语言环境：http://static.springsource.org/spring/docs/2.5.x/api/org/springframework/web/servlet/support/RequestContextUtils.html#getLocale(javax.servlet . http.HttpServletRequest)
import org.springframework.web.servlet.support.RequestContextUtils
def locale = RequestContextUtils.getLocale(request)

You can also use the LocaleContextHolderwhich doesn't need a request as a parameter
您还可以使用LocaleContextHolder不需要请求的参数作为参数
import org.springframework.context.i18n.LocaleContextHolder;
LocaleContextHolder.getLocale();

If you display propertiesof RequestContextUtils.getLocale(request), you will find the following :
如果显示properties的RequestContextUtils.getLocale(request)，你会发现以下内容：

class=class java.util.Locale
default=fr_FR
