Externalize application properties in a Grails app
Externalizing properties of an application has really come a long way, especially if you are using Grails.
Just want to share as a quick tip how easy it is to externalize the properties in a Grails application.
This is what all we have to do in-order to get something from a properties file.
In config.groovy include the properties that you want to be outside your groovy code.
For Example :
smtpUserName = "<firstname.lastname@example.org>"
hostname = "yourHostName"
In order to read these properties in your Grails controller:
def smtpUserName = grailsApplication.config.smtpUserName
In order to read the properties from Grails Service class:
def smtpUserName = ConfigurationHolder.config.smtpUserName
Easy, isn’t it?
Oww! great 🙂
When I initially commented I clicked the “Notify me when new comments are added” checkbox
andd now eqch time a comment iis added I get several emails
with the same comment. Is there any way you can remove
me from that service? Thank you!
