Question

we currently use configuration files to store application settings. I was wondering if it is possible to store these settings inside the database and if so how to achieve this?

Greetings

You can store whatever you want in the database and read it out using a Domain class. This is especially useful if you want to be able to make changes to things without having to redeploy new code. But realize that you will incur a database hit every time the property is accessed.

You can set up a ConfigurationService with:

ConfigurationService {
    static def configurationValues

    def getConfigurationValues() {
        if(configurationValues == null) {
            refreshConfigurationValues()
        }
        configurationValues
    }

    def refreshConfigurationValues() {
        configurationValues = //go get the values out of the database
    }
}

Then you can add a Controller/Action to force the refresh when necessary

ConfigurationController {

    def configurationService

    def refreshConfiguration = {
        configurationService.refreshConfigurationValues()
        render "Ahhh... That's refreshing :)"
    }
}

Now you can refresh your config values by invoking: “http://yoururl/appName/configuration/refreshConfiguration”
