我搜索了互聯(lián)網(wǎng)的大部分，但沒有找到明確的答案......我想做一件簡單的事情：就像在 Grails 中一樣，有一個單例MessageSource類型可以在控制器中使用它來顯示 i18n 消息。我想messageSource從這個文件初始化我的：src/main/resources/my/package/i18n/Messages*.propertiestest=FooBar初始化嘗試：class AppConfig { @Singleton MessageSource messageSource() { new ResourceBundleMessageSource( 'my.package.i18n.Messages' ) }}要注入的控制器：class CRUDController<T> { @Inject MessageSource messageSource @Transactional( readOnly=true ) @Get( '/' ) Map<String,Object> list() { log.info "$messageSource -> ${messageSource.getMessage( 'test', MessageSource.MessageContext.DEFAULT )}" [:] }}日志信息打印如下：io.micronaut.runtime.context.CompositeMessageSource@79a1d030 -> Optional.empty因此， messageSource 以某種方式（和某處）被錯誤初始化。做這個簡單的事情最簡單直接的方法是什么？

test=FooBar
這一切似乎都有效：
$ curl localhost:8080/people
FooBar
