Grails - getting a message value from controller
How can I get a value from message properties outside of GSPs? For instance, th开发者_如何转开发e equivalent of
<g:message code="some.message"/>
but in a controller?
Inside a controller or a taglib, you can use the following :
g.message(code: 'some.message')
However, inside domain classes or services, you need to inject messageSource and call getMessage() method from Sping class AbstractMessageSource. This snippet shows you how to do that:
import org.springframework.context.i18n.LocaleContextHolder as LCH
...
class MyServiceOrMyDomain {
def messageSource
...
messageSource.getMessage(code, msgArgs, defaultMsg, LCH.getLocale())
...
}
You can also import the validation tag lib and use it grab the message source.
import org.codehaus.groovy.grails.plugins.web.taglib.ValidationTagLib
def g = new ValidationTagLib()
g.message(error: error)
