docker - docker-compose 构建语言切换后不起作用

Question

在 docker 容器中添加我的应用程序后，语言切换无法正常工作......我发现切换部分有效。从数据库中提取的对象以所需的语言显示。取自 messages.properties 的文本仅以英文显示。虽然我添加了两种语言（俄语和英语）。为什么会发生这种情况以及如何解决这个问题？

我猜这个案子可能在messageSource.setBasename ("classpath: messages")。

@Configuration
class WebConfig: WebMvcConfigurer {

    @Bean
    fun  localeResolver(): LocaleResolver {
        val slr = SessionLocaleResolver()
        slr.setDefaultLocale(UtilsLocale.getDefault())
        return slr;
    }

    @Bean
    fun localeChangeInterceptor(): LocaleChangeInterceptor {
        val lci = LocaleChangeInterceptor()
        lci.paramName = "language"
        return lci
    }

    @Bean
    fun messageSource(): MessageSource {
        val messageSource = ReloadableResourceBundleMessageSource()
        messageSource.setBasename("classpath:messages")
        messageSource.setDefaultEncoding("UTF-8")
        return messageSource
    }

    @Bean
    fun validator(): LocalValidatorFactoryBean {
        val bean = LocalValidatorFactoryBean()
        bean.setValidationMessageSource(messageSource())
        return bean
    }

    override fun addInterceptors(registry: InterceptorRegistry) {
        registry.addInterceptor(localeChangeInterceptor())
    }

}

@Component
object UtilsLocale {
    val LOCALE_RU = Locale("ru", "RU")
    val LOCALE_EN = Locale.ENGLISH

    fun getDefault(): Locale = LOCALE_RU

    fun getAll(): Array<Locale> = arrayOf(LOCALE_RU, LOCALE_EN)
}

这是 Dockerfile：

编辑：添加messages_ru_RU.properties文件后，标准语言变成了俄语，但是当我选择切换到英语时，语言并没有切换回来......

已编辑：切换后在 html 语言中设置正常
