Question

如果有帮助，我们确实配置了LocaleChangeInterceptor。

（最初发布到http://forum.springsource.org/showthread.php?123391-Transition-to-set-locale）

Answer 1

这不是我想要的，但这是我发现的唯一的事情。也就是说，我创建了一个从转换中调用的动作方法：

    <transition on="switchLanguage" validate="false">
        <evaluate expression="myAction.switchLanguage"/>
    </transition>

和

public Event switchLanguage(RequestContext context)
{
    // get the "other" locale string itself from the current locale's resource bundle
    Locale locale = context.getExternalContext().getLocale();
    MessageSource ms = context.getActiveFlow().getApplicationContext();
    String newLocaleString = ms.getMessage("lang.other", null, locale);

    HttpServletRequest req = (HttpServletRequest) context.getExternalContext().getNativeRequest();
    HttpServletResponse res = (HttpServletResponse) context.getExternalContext().getNativeResponse();

    LocaleResolver localeResolver = RequestContextUtils.getLocaleResolver(req);
    localeResolver.setLocale(req, res, StringUtils.parseLocaleString(newLocaleString));
    return success();
}

最好是使用现有组件。这是Spring WebFlow的片段，配置为使用“LocaleChangeInterceptor”：

@Bean
public FlowHandlerMapping flowHandlerMapping(FlowDefinitionRegistry flowDefinitionRegistry) {
    FlowHandlerMapping handlerMapping = new FlowHandlerMapping();
    handlerMapping.setInterceptors(new Object[] { localeChangeInterceptor() });
    // ... other configuration
    return handlerMapping;
}

/**
 * @category locale_switcher
 */
@Bean
public SessionLocaleResolver localeResolver() {
    SessionLocaleResolver localeResolver = new SessionLocaleResolver();
    localeResolver.setDefaultLocale(Locale.ENGLISH);
    return localeResolver;
}

/**
 * @category locale_switcher
 */
@Bean
public LocaleChangeInterceptor localeChangeInterceptor() {
    LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();
    localeChangeInterceptor.setParamName("lang");
    return localeChangeInterceptor;
}

定义转换切换区域设置并返回当前视图状态的最简单方法是什么？
