从正确的i18n属性文件中检索JSF中的密钥

Question

有人知道下一个方法有什么问题吗？

public static String getMessageBundleString(String key, String localeAcronym) throws MissingResourceException {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    String messageBundleName = facesContext.getApplication().getMessageBundle();
    ResourceBundle bundle = ResourceBundle.getBundle(messageBundleName, new Locale(localeAcronym));
        //THE LOCALE OF THIS BUNDLE IS ALWAYS 'es_ES' !!!
    return bundle.getString(key);
}

在Primefaces/JSF环境中，我希望从正确的i18n属性文件中检索密钥。

但是它总是从messages_es_ES.properties文件中获取。

以下调用返回相同的值 (='Inicio')：

getMessageBundleString("home", "es_ES")
getMessageBundleString("home", "uk_UK")

messages_es_ES.properties:
home=Inicio

messages_uk_UK.properties:
home=Home

谢谢

下面是我的一些faces-config.xml内容：

<application>
    <locale-config>
        <supported-locale>es_ES</supported-locale>
        <supported-locale>uk_UK</supported-locale>
    </locale-config>    
    <message-bundle>cfg.i18n.messages</message-bundle>
    <resource-bundle>
        <base-name>cfg.i18n.messages</base-name>
        <var>msgs</var>
    </resource-bundle>
</application>

这一备选案文起作用(将国家和语言分开)：

public static String getMessageBundleString(String key, String language, String country) throws MissingResourceException {
    FacesContext facesContext = FacesContext.getCurrentInstance();
    String messageBundleName = facesContext.getApplication().getMessageBundle();
    ResourceBundle bundle = ResourceBundle.getBundle(messageBundleName, new Locale(language, country));
        //Valid ones: "es","ES"; "en","GB"!!!
    return bundle.getString(key);
}

你试过这种变体了吗？

getMessageBundleString("home", "es")
getMessageBundleString("home", "en")
messages_es.properties:
home=Inicio
messages_en.properties:
home=Home
