最後,我找到了答案 - 覆蓋默認的Grails爲messageSource:
class ExtendedPluginAwareResourceBundleMessageSource extends PluginAwareResourceBundleMessageSource {
Map<String, String> listMessageCodes(Locale locale) {
Properties properties = getMergedProperties(locale).properties
Properties pluginProperties = getMergedPluginProperties(locale).properties
return properties.plus(pluginProperties)
}
}
在的grails-app/conf目錄/春/ resources.groovy:
beans = {
messageSource(ExtendedPluginAwareResourceBundleMessageSource) {
basenames = "WEB-INF/grails-app/i18n/messages"
}
}
通訊控制器代碼:
class MessageController {
def messageSource
def index = {
def messageMap = messageSource.listMessageCodes(request.locale)
render (contentType: "text/xml") {
messageMap {key, message ->
..
}
}
}
}
