如何在Spring中处理多个文件和消息以实现国际化？ [英] How to handle multiple files and messages for internationalization in Spring?

问题描述

有关Spring国际化的文章讲述了如何交换传递语言环境等的消息，但我只发现包含一些消息的用例 ..

Some articles about Spring internationalization tell how to swap messages passing the locale and etc, but I only found use cases that contains a few messages..

• 如何根据上下文组织和使用国际化文件？ （验证，查看消息，默认消息，业务消息）

• How can I organize and use internationalization files per context? (validation, view messages, default messages, business messages)

我知道Spring使用模式（定义的消息文件的名称）+
locale 。 例如：message_zh_CN 。如何知道
关于此行为的每个上下文文件？

I know that Spring uses the pattern (name of message file defined) + locale. e.g: message_zh_CN. How can I have files per context knowing about this behavior?

我认为它应该是：

resources
`-- messages
    |-- validation
    |   |-- message_locale.properties
    |   `-- message_locale2.properties
    |-- business
    |   |-- message_locale.properties
    |   `-- message_locale2.properties
    `-- view
        |-- message_locale.properties
        `-- message_locale2.properties

或者：

resources
`-- messages
    |-- validation
    |   |-- validation_locale.properties
    |   `-- validation_locale2.properties
    |-- business
    |   |-- business_locale.properties
    |   `-- business_locale2.properties
    `-- view
        |-- view_locale.properties
        `-- view_locale2.properties

推荐答案

您可以为所有这些不同的消息文件定义全局 MessageSource 。使用 setBasenames 方法这种方法很实用：

You can either define a global MessageSource for all those different message files. This approach is practical using the setBasenames method:

@Bean
public MessageSource messageSource() {
    ReloadableResourceBundleMessageSource messageSource = 
                                               new ReloadableResourceBundleMessageSource();
    messageSource.setBasenames("classpath:/messages/business/message", 
                               "classpath:/messages/validation/message",
                               "classpath:/messages/view/message");

    return messageSource;
}

如果您的消息密钥在所有文件中都是唯一的，例如 business-12 密钥仅退出与业务相关的消息来源。否则，最好根据您的上下文定义一个 MessageSource 并根据您的上下文注入它们：

This approach makes sense if your message keys are unique across all files, e.g. business-12 key only exits in business related message sources. Otherwise, it's better to define one MessageSource per context and inject them according to your context:

@Bean
public MessageSource businessMessageSource() {
    ReloadableResourceBundleMessageSource messageSource = 
                                               new ReloadableResourceBundleMessageSource();
    messageSource.setBasename("classpath:/messages/business/message");

    return messageSource;
}

@Bean
public MessageSource validationMessageSource() {
    ReloadableResourceBundleMessageSource messageSource = 
                                               new ReloadableResourceBundleMessageSource();
    messageSource.setBasename("classpath:/messages/validation/message");

    return messageSource;
}

@Bean
public MessageSource viewMessageSource() {
    ReloadableResourceBundleMessageSource messageSource = 
                                               new ReloadableResourceBundleMessageSource();
    messageSource.setBasename("classpath:/messages/view/message");

    return messageSource;
}
