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..
How can I organize and use internationalization files per context? (validation, view messages, default messages, business messages)
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?
What I think it should be:
resources
`-- messages
|-- validation
| |-- message_locale.properties
| `-- message_locale2.properties
|-- business
| |-- message_locale.properties
| `-- message_locale2.properties
`-- view
|-- message_locale.properties
`-- message_locale2.properties
OR:
resources
`-- messages
|-- validation
| |-- validation_locale.properties
| `-- validation_locale2.properties
|-- business
| |-- business_locale.properties
| `-- business_locale2.properties
`-- view
|-- view_locale.properties
`-- view_locale2.properties
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;
}
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;
}
