code fail at grailsApplication.config.grails.binRange. any one can solve this?

Question

We are upgrading grails 2.4.4 to 3.6.6, but the code failed at grailsApplication.config.grails.binRange. Any idea why I am not able to access grails from config. anyone can solve this?

Answer 1

The default configuration file for Grails 3 applications is grails-app/conf/application.yml . In this file, YAML syntax is supported.

The GrailsApplication interface defines the getConfig method which returns a Config object. In the Spring application context is a bean named grailsApplication which is an instance of a class which implements the GrailsApplication interface. Retrieving the config object from this bean is one way to gain access to config values.

For Example: grails-app/conf/application.yml

max:
    line:
        numbers: 42

OR

max.line.numbers: 42

grails-app/init/BootStrap.groovy

import grails.core.GrailsApplication

class YourController{

    GrailsApplication grailsApplication

        // retrieve the max.line.numbers config value
        def maxLineNumbers =  grailsApplication.config.getProperty('max.line.numbers')

}
