为什么我需要Spring Boot`messages.properties`而不是`messages_en.properties`? [英] Why do I need Spring Boot `messages.properties` instead of just `messages_en.properties`?

问题描述

我正在遵循本指南，并说要命名默认消息文件作为messages.properties.为什么我不能将其命名为messages_en.properties并将默认语言环境设置为英语?

I'm following this guide and it says to name the default messages file as messages.properties. Why can't I name it messages_en.properties and set the default locale to English?

@Bean
public LocaleResolver localeResolver() {
    SessionLocaleResolver slr = new SessionLocaleResolver();
    slr.setDefaultLocale(Locale.ENGLISH);
    return slr;
}

这不起作用(每次重新命名message.properties时都必须硬停止并重新启动服务器-动态重载无法获取更改).它将打印出带有诸如<spring:message code="oops" text="default"/>之类的标签的default文本，因为找不到messages_en.properties.

This doesn't work (have to hard stop and restart the server each time message.properties is renamed - dynamic reload fails to pick up the changes). It will print out default text with a tag like <spring:message code="oops" text="default"/> because it can't find messages_en.properties.

实际上，当我将浏览器默认语言设置为法语并设置为messages_fr.properties并重新启动服务器时，它也同样找不到法语的密钥.

In fact, when I set my browser default language to French and have messages_fr.properties, and restart the server, it is also failing to find the keys for French as well.

不使用Thymeleaf.无需允许用户选择语言.

Not using Thymeleaf. No need to allow user-selectable language.

推荐答案

我通过使用

I fixed it by using AcceptHeaderLocaleResolver instead.

@Bean
public LocaleResolver localeResolver() {
    AcceptHeaderLocaleResolver ahlr = new AcceptHeaderLocaleResolver();
    ahlr.setDefaultLocale(Locale.ENGLISH);
    return ahlr;
}

我以为该指南说它将在会话，cookie或标头中搜索语言环境，但他们只是说不同的子类分别实现了这些功能.

I thought the guide said it will search for the locale in the session, cookie, or header, but they were only saying that different sub-classes implement those features separately.

LocaleResolver接口具有可根据会话，cookie，Accept-Language标头或固定值确定当前语言环境的实现.

The LocaleResolver interface has implementations that determine the current locale based on the session, cookies, the Accept-Language header, or a fixed value.

我通过设置此应用程序属性，至少用于调试:

I fixed the live reload problem by setting this application property, at least for debugging:

spring.messages.cache-seconds=1

我还设置了此属性，以免弄乱我的src/main/resources文件夹，因此我可以将所有邮件文件移到locales/子目录中.

I also set this property so as not to clutter up my src/main/resources folder, so I could move all the message files into the locales/ sub-directory.

spring.messages.basename=locales/messages
