HttpServletRequest getLocale返回OS语言环境而不是浏览器语言环境 [英] HttpServletRequest getLocale returns OS locale not browser locale

问题描述

  @Override 
 public void onRequestStart（HttpServletRequest请求，
 HttpServletResponse响应）{
 currentIP = request.getRemoteAddr（）; 
 setLocale（request.getLocale（））; 
 handle.set（this）; 
 this.request = request; 
 this.response = response; 
} 
  

但是，request.getLocale（）返回 en_US ，这是我的操作系统区域设置。但是，在Firefox插件切换语言环境（ https：/ /addons.mozilla.org/cs/firefox/addon/quick-locale-switcher/?src=userprofile ），我已经将它设置为 cs_CZ getLocale（）仍然会返回 en_US 。

获取会话语言环境：
$ b $ pre $ UI.getCurrent（）。getSession（）。getLocale（）;


这对我有用。

I am using vaadin framework and in my application I have:

@Override
public void onRequestStart(HttpServletRequest request,
        HttpServletResponse response) {
    currentIP = request.getRemoteAddr();
    setLocale(request.getLocale());
    handle.set(this);    
    this.request = request;    
    this.response = response;
}

however, request.getLocale() returns en_US, which is my OS locale. However, in Firefox addon for switching locales (https://addons.mozilla.org/cs/firefox/addon/quick-locale-switcher/?src=userprofile), I have set up it to be cs_CZ, however, getLocale() will still return en_US.

解决方案

Try getting the session locale:

UI.getCurrent().getSession().getLocale();

That worked for me.
