Playframework 2.0.1DateFormatter接收系统区域设置 [英] Playframework 2.0.1DateFormatter receives system locale

问题描述

我在Play 2.0/Java中编写了一个自定义的DateFormatter，因为默认值似乎是i18n不知道的(实现细节与此处无关)

I wrote a custom DateFormatter in Play 2.0 / Java because the default one seems to be i18n-unaware (the implementation details are irrelevant here)

public class DateFormatter extends Formatters.SimpleFormatter<Date>

我的应用程序配置包含

application.langs="pt-br, en"

浏览器选项中定义的语言包含这两种(接受语言)

The languages defined in browser options contain those two (accept-language)

从逻辑上讲，Lang.preferred(List)返回pt-br作为首选语言，如

Logically, Lang.preferred(List) returns pt-br as preferred language like in

@Override
public Action onRequest(Request request, Method method) {

    Lang preferred = Lang.preferred(request.acceptLanguages());
    Logger.debug("Preferred language is " + preferred.toLocale());

    return super.onRequest(request, method);
}

但是(可悲的是)

我的自定义DateFormatter在

the locale received by my custom DateFormatter in

@Override
public Date parse(String date, Locale locale)  {
    ...
}

是系统(JVM)的语言环境(在美国)，并且不请求首选的语言环境.

is system's (JVM) locale, en-US, and not request preferred one.

这正常吗?我在这里想念什么?

Is this normal ? What am I missing here ?

推荐答案

我认为您可以使用以下解决方法:

I think you can use this workaround:

对于每个请求，使用全局拦截器，您可以设置LocaleContextHolder设置您的请求的语言环境:

For each request, using the Global interceptor, you can set the LocaleContextHolder to set the Locale of your request:

public class Global extends GlobalSettings {

    @Override
    public Action onRequest(final Request request, Method actionMethod) {
        LocaleContextHolder.setLocaleContext(new LocaleContext() {
            public Locale getLocale() {
                            Lang preferred = Lang.preferred(request.acceptLanguages());
                return preferred.toLocale();
            }
        });
        return super.onRequest(request, actionMethod);
    }

}

我没有测试它，但是值得一试:-)

I did not test it, but it's worth the shot :-)
