Question

我在Spring MVC中遇到i18n问题。当我调用此方法来获取当前语言环境时：

public static final Locale DEFAULT_LOCALE = new Locale("en", "GB");

public Locale getLocale() {
    if (RequestContextHolder.getRequestAttributes() != null) {
        final HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder
                .getRequestAttributes()).getRequest();
        final LocaleResolver localeResolver = RequestContextUtils
                .getLocaleResolver(request);
        if (localeResolver != null) {
            Locale locale = localeResolver.resolveLocale(request);
            if (locale != null) {
                return locale;
            }
        }
    }
    return DEFAULT_LOCALE;
}

它返回正确的语言环境但没有设置国家/地区属性。

public String getCurrency() {
    Locale locale = getLocale();
    System.err.println("Locale: " + getLocale());
    String country = locale.getCountry();
    System.err.println("Country: " + country);
    String displayCountry = locale.getDisplayCountry();
    System.err.println("displayCountry: " + displayCountry);
    String displayName = locale.getDisplayName();
    System.err.println("displayName: " + displayName);
    Currency currency = Currency.getInstance(locale);
    System.err.println("Currency.getSymbol() = " + currency.getSymbol());
    return currency.getSymbol();
}

此方法打印：

Locale: ro
Country: 
displayCountry: 
displayName: Romanian

我实际上需要获取区域设置货币，但这会调用Currency.getInstance（locale）;抛出java.lang.IllegalArgumentException，因为country属性为空。

这是我用于国际化的配置文件：

<bean id="messageSource" class="org.springframework.context.support.ReloadableResourceBundleMessageSource">
    <property name="basename" value="classpath:messages" />
    <property name="defaultEncoding" value="UTF-8" />
</bean>

<bean id="localeResolver" class="org.springframework.web.servlet.i18n.CookieLocaleResolver">
   <property name="defaultLocale" value="en" />
</bean>

<mvc:interceptors>
    <bean id="localeChangeInterceptor" class="org.springframework.web.servlet.i18n.LocaleChangeInterceptor">
        <property name="paramName" value="lang" />
    </bean>
</mvc:interceptors>

我认为问题在于，当我选择一个新国家时，它只会改变语言。

以下是我更改语言的地方：

<a class="country_flag" href="?lang=uk">United Kingdom</a>
<a class="country_flag" href="?lang=ro">Romania</a>

我使用SessionLocaleResolver，它对我有用：

<bean id="localeResolver"
    class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
    <property name="defaultLocale" value="ru_RU" />
</bean>

注意 - 值应为xx_XX，尽管jsp中的lang = xx：

    <li><a href="?lang=en"><img src="<c:url value="/resources/languages/en.png"/>" border="0"/></li>
    <li><a href="?lang=ru"><img src="<c:url value="/resources/languages/ru.png"/>" border="0"/></li>

Spring MVC国际化，Locale country属性为空
