我必须使用 JSF2 实现基于域的 I18N。
例如，如果域是
www.bookstore.com --> it should go to english site
www.bookstore.com.cn --> it should go to chinese site
www.bookstore.co.jp --> it should go to japanese site
我们拥有所有经过适当翻译的属性文件。当我更改浏览器语言/区域设置时，我可以看到翻译后的内容。但我们实际上并不需要这种行为。我在过滤器中根据域设置语言环境，它似乎不起作用。这是我的代码，这段代码有什么问题，问题出在哪里？

当我从不同的域尝试[我已经在本地更改了我的主机文件]时，当我调试过滤器代码时，它会根据域提供正确的区域设置。但不知道为什么总是得到英文内容。但是如果我更改浏览器语言，我可以看到翻译后的内容。这段代码有什么问题？
