Grails: Change contents of message.properties (i18n) in production

Question

Is is possible to modify text in message.properties when in production without a redeploy/restart.

Answer 1

It's quite possible, but you need to replace the default messageSource bean with a ReloadableResourceBundleMessageSource. You can do this by configuring a new messageSource bean definition in your grails-app/conf/spring/resources.groovy as follows:

beans = {
      messageSource(org.springframework.context.support.ReloadableResourceBundleMessageSource) {
        basenames = ["classpath:grails-app/i18n/myApp", "file:grails-app/i18n/messages", "WEB-INF/grails-app/i18n/messages"]
    }
}

The above will work in both development and production. You may also want to research other options available to you using the ReloadableResourceBundleMessageSource.
