Dynamic Quartz Configuration in Grails 3 - grails

Question

In Grails 2, we had the following block of code in our Config.groovy file. The ConfigurationManagement class did a runtime lookup in a Configuration Management Database to determine if the quartz.autoStartup parameter should be true or false. We also used similar configuration to load additional Quartz properties.
quartz {
def autoStartupOnTheseServers = ConfigurationManagement.getValue("myApp.quartz.autoStartupOnTheseServers", "").split(",")
if ( autoStartupOnTheseServers.any { it.trim().toUpperCase() == hostName.toUpperCase() } ) {
autoStartup = true
}
else {
autoStartup = false
}
// Default for clustering (jdbcStore) has to be "false" so the app will run locally.
// Clustering (jdbcStore) will be true for DEV, TEST, QA, and PROD (set by Configuartion Management).
jdbcStore = ConfigurationManagement.getValue("myApp.quartz.jdbcStore", "false").toBoolean()
// don't set the props if not enabling quartz clustering...causes an exception.
if(jdbcStore == true) { props(quartzProps) }
}
In Grails 3, similar code used in application.groovy doesn't work and there isn't any facility for conditionals that I can find for application.yml. Is there any way in Grails 3 to do a similar dynamic configuration?

Answer 1

In Grails 3, it seems that you can't set these values directly, but you can declare a local variable and use that to set the property. So, for my example above, the following works:
def extServerList = ConfigurationManagement.getValue("myApp.quartz.autoStartupOnTheseServers", "").split(",")
def extAutoStartup = extServerList.any { it.trim().toUpperCase() == hostName.toUpperCase() }
def extJdbcStore = ConfigurationManagement.getValue("myApp.quartz.jdbcStore", "false").toBoolean()
quartz {
autoStartupOnTheseServers = extServerList
autoStartup = extAutoStartup
jdbcStore = extJdbcStore
}
